A structural insulated panel (SIP) includes a core of insulation sandwiched between two structural skins--usually made of wood or OSB. An insulated metal panel (IMP) includes a core of insulation sandwiched between two diffusion-resistant metal skins. SIPs tend to be best suited for roof and wall elements in residential or light commercial construction, while IMPs are usually found in larger commercial and industrial construction and specialty applications such as cold storage facilities. IMPs are also sometimes used for residential construction in extremely cold climates.
There are three major differences. First, BASF uses the versatility of chemistry to offer a closed-cell content of greater than 90 percent for all of its roofing and air barrier formulations, and open-cell foams commonly used as insulation systems have approximately 60 percent open-cell content. Second, closed-cell foam offers an R-value of over 6.0 per inch and open cell offers between 3.0 and 3.9 per inch. Third, closed-cell foam is virtually impermeable to air, while most open-cell foams do not offer the air leakage performance required to qualify as an air barrier. However, open-cell foam is less expensive, and offers better sound absorption.

Yes. There are many factors that contribute to the sustainability of SPF roofing systems. First, no tear-off of the existing roof is required in 98% of re-roofing applications, which diverts thousands of tons of waste from landfill. Second, they are extremely durable, offering industry-leading resistance to severe weather including wind uplift and impact from airborne debris. Third, they offer an extremely long life expectancy of 20 years or more, and are renewable indefinitely with simple recoats. And fourth, they make a significant contribution to building energy efficiency. One Texas A&M study showed the university was able to pay for the cost of their new SPF roofs in 4.5 years though energy savings! And when they are combined with reflective coatings, SPF roofing systems also help combat urban heat island effect and reduce smog.

In the case of conventional hydro bearings, the rubber end stop, which is subject to high dynamic loads, can wear away through friction. This results in the bearing ceasing to work properly before its time. So the usable life of the hydro bearing needs to be extended without the component geometry being changed. This can be done using an end stop (clip) made of Cellasto®, which is extremely resistant to friction.

This microcellular polyurethane elastomer is used to create auxiliary springs, support bearings and chassis components. Its excellent characteristics ensure a reduction in NVH and a clear increase in comfort and road dynamics. BASF is the world leader in microcellular polyurethane components.
How do polyurethane-based composite parts compare with vinyl esters or polyesters?
BASF urethane composites add strength while reducing weight in all kinds of RV and ATV components. This includes better impact resistance, similar HDT (Heat Deflection Temperature) and 25% less weight than parts made of vinyl esters or polyesters. BASF composites also offer molding efficiencies, reduce emissions during molding and eliminate VOCs.
The density of these moldings range from 350 kg/m³ to 650 kg/m³ depending on the mass of material used. Their cell volume amounts to 63% to 50% of the molding volume. The cell diameter amounts to tenths of a millimeter and the cells can be open or closed depending on the density. Compression loads first compress the cell volume and later the material itself. It therefore becomes harder as compression increases.

The outstanding features of Cellasto® are:
- Low compression set
- High volume compressibility with minimum lateral expression
- Excellent mechanical properties & durability
- Highly versatile - noise isolation at small amplitude & high frequency; vibration isolation at large amplitude & low frequency
- Abrasion resistant
- Resistant to ozone, oils, greases and other aliphatic hydrocarbons
Compact elastomers such as rubber, for instance, respond to compression with high lateral expansion. Cellular polyurethane elastomers, however, only create very low lateral expansion.

The pneumatic spring is reduced in size in accordance with the load taken on by the spring aid. Because of Cellasto®'s negligible lateral expansion, the flow holes are not closed - even if the spring aids deflect to the maximum. Cellasto® spring aids have sufficient emergency operation properties and can take over all of the suspension work should the pneumatic spring fail.

A structural insulated panel (SIP) includes a core of insulation sandwiched between two structural skins--usually made of wood or OSB. An insulated metal panel includes a core of insulation sandwiched between two diffusion-resistant metal skins. SIPs tend to be best suited for roof and wall elements in residential or light commercial construction, while IMPs are usually found in larger commercial and industrial construction and specialty applications such as cold storage facilities. IMPs are also sometimes used for residential construction in extremely cold climates.
There are three major differences. First, BASF uses the versatility of chemistry to offer a closed-cell content of greater than 90 percent for all of its roofing and air barrier formulations, and open-cell foams commonly used as insulation systems have approximately 60 percent open-cell content. Second, closed-cell foam offers an R-value of over 6.0 per inch and open cell offers between 3.0 and 3.9 per inch. Third, closed-cell foam is virtually impermeable to air, while most open-cell foams do not offer the air leakage performance required to qualify as an air barrier. However, open-cell foam is less expensive, and offers better sound absorption.

High-density polyurethane foams used for these applications offer a low H2O absorption rate and moisture-resistance (water absorption rate under 1% by volume) that does not attract mold, fungus, rot or insects. And because it is designed for low maintenance, BASF high density foam can take varying temperatures and climates and maintain appearance.
Yes. There are many factors that contribute to the sustainability of SPF roofing systems. First, no tear-off of the existing roof is required in 98% of re-roofing applications, which diverts thousands of tons of waste from landfill. Second, they are extremely durable, offering industry-leading resistance to severe weather including wind uplift and impact from airborne debris. Third, they offer an extremely long life expectancy of 20 years or more, and are renewable indefinitely with simple recoats. And fourth, they make a significant contribution to building energy efficiency. One Texas A&M study showed the university was able to pay for the cost of their new SPF roofs in 4.5 years though energy savings! And when they are combined with reflective coatings, SPF roofing systems also help combat urban heat island effect and reduce smog.

BASF polyurethane adhesives provide exceptional bonding to a wide variety of substrates, over a significant range of temperatures. They help cut time, labor, construction and assembly costs. They work well with other BASF polyurethane chemistries and are available with the same industry-leading technical service support.
Wide-ranging one- and two-component formulas are available, based on physical property or processing needs. Adhesives can be made to a range of hardness, elasticity, water or chemical resistance, or wide temperature range performance. Formulations can react to create the strongest possible adhesion to wood, or to bond other substrates such as EPS, OSB or specific metals.
BASF offers adhesives that are 100% solids, containing no solvents or volatile organic compounds (VOCs).
A recent BASF fast binder study compared the two formulas using aspen at a face/core/face ratio of 25/50/25, platen temperature of 210 C and 1% wax emulsion for all panels. Test panels included 7/16" (2.5% PMDI dosage), 23/32" and 1" (both 4.5% PMDI dosage). The results showed that Lupranate® M20FB reacts faster and gives stronger bonding. However, moisture content was found to be very important. FB with 4% MC was faster than SB, and FB with 6% MC improved performance.
Elastocast™ polyurethane elastomers have exceptional tensile, tear and elongation properties, which makes them an ideal solution for reinforcing building panels or metal construction of any kind. They're stable over wide ranging temperatures and can be made highly resilient to impact, abrasion, cutting or tearing. They also can be filled for additional physical properties and to lower system cost. Spray-applied elastomers are often used in composites to add strength, protection or aesthetics to other materials. Good elongation and anticorrosion properties make cast elastomers well-suited for pipe coatings. And formulations that require resilience and tear strength properties are ideal for molds and concrete stamps. You'll also find them being used on expansion joints in bridge construction, in rail applications for highway crossings and for rail spike adhesives.

BASF elastomers can be molded to almost any size, shape and texture. This makes them well suited to producing everything from wristwatch straps to molds for simulated stone and outdoor decking to retail store mannequins.
Polyurethane is any polymer—a large molecule of repeating structural units—composed of a chain of organic units, joined by urethane links. It includes natural and synthetic materials with a variety of properties. Polyurethanes are the most versatile of all the polymers and can be made liquid, rigid, pliable and stretchable, and can be spread, sprayed or molded.

In the case of conventional hydro bearings, the rubber end stop, which is subject to high dynamic loads, can wear away through friction. This results in the bearing ceasing to work properly before its time. So the usable life of the hydro bearing needs to be extended without the component geometry being changed. This can be done using an end stop (clip) made of Cellasto®, which is extremely resistant to friction.

Polyurethane helps reduce vehicle weight without sacrificing strength and durability. BASF's innovative polyurethane composite systems are being used to reduce the weight of load floors in a variety of vehicle types and platforms. From incredibly thin honeycomb cores encapsulated in LFI (long-glass fiber injection) polyurethane, to rigid polyurethane foam cores sandwiched between hardboard skins, BASF offers an affordable solution for every load floor application.
Far stiffer than traditional polypropylene floors and far lighter than hardboard floors, load floors made with polyurethane composites take mass out of your vehicles while improving strength.
In addition, the design flexibility offered by polyurethane helps enhance aerodynamics and reduce the weight of mudguards, bumpers, door sills, spoilers, hoods, wing mirror housings and roof modules.
This microcellular polyurethane elastomer is used to create auxiliary springs, support bearings and chassis components. Its excellent characteristics ensure a reduction in NVH and a clear increase in comfort and road dynamics. BASF is the world leader in microcellular polyurethane components.
How do polyurethane-based composite parts compare with vinyl esters or polyesters?
BASF urethane composites add strength while reducing weight in all kinds of RV and ATV components. This includes better impact resistance, similar HDT (Heat Deflection Temperature) and 25% less weight than parts made of vinyl esters or polyesters. BASF composites also offer molding efficiencies, reduce emissions during molding and eliminate VOCs.
The density of these moldings range from 350 kg/m³ to 650 kg/m³ depending on the mass of material used. Their cell volume amounts to 63% to 50% of the molding volume. The cell diameter amounts to tenths of a millimeter and the cells can be open or closed depending on the density. Compression loads first compress the cell volume and later the material itself. It therefore becomes harder as compression increases.

Cellasto®: Polyurethanes for the automotive industry
Cockpit ambience: How polyurethanes contribute to automotive design
Wide-ranging one- and two-component formulas are available, based on physical property or processing needs. Adhesives can be made to a range of hardness, elasticity, water or chemical resistance, or wide temperature-range performance. They help cut time, labor, manufacturing and assembly costs. Our adhesives also work well with other BASF polyurethane chemistries and are available with the same industry-leading technical service support.
There are many factors to improving ergonomics in heavy trucks, and polyurethanes contribute in many areas. Acoustic foams minimize road and engine noise, creating a comfortable working environment for the driver, while sound deadening carpet underlay keeps road noises from penetrating the cockpit. For a firm and secure grip that is comfortable for miles on end, big rig steering wheels are made with Elastofoam® integral skin.
Long distance professional drivers need seats and bedding that are comfortable and durable, as well as supportive to reduce ergonomic strain. Elastoflex® provides exceptional support and resiliency, so it’s as comfortable on the first mile as it is on the last. The sleeping cabin is the driver’s home on the road and has to be comfortable, attractive and secure.
BASF polyurethane composites incorporated into the walls ensures sleeper cabins are well insulated from weather and noise. Incorporating Elastoskin® plus Elastoflex® provides truck designers with the flexibility to create warm, comfortable and durable cabin walls in almost any color, grain or texture using a single, in-mold process.
