Building & Construction

Plastics are now being used for an increasingly wide range of building and construction applications.

 

  • In window profiles, plastics have better insulating properties than aluminum ones and require less maintenance than wooden ones.
  • Plastic decking and fencing require less maintenance then wooden alternative and are more durable.
  • In films, plastics enhance the glass properties of windows, making them safer or more energy efficient.
  • Plastic flooring provides wide scope for design and is more practical than other materials for demanding applications such as sports arenas.
  • In pipes, plastics are easier to install and maintain than those made of traditional materials.
  • Plastic membranes offer greater technical and esthetic flexibility than traditional materials in applications requiring waterproofing, such as roofing, basements, and swimming pools.
  • In glazing, plastics are lighter in weight than glass, allowing less massive building structures.

Thermal stabilizers protect plastics from oxidation caused by exposure to heat and help to prevent loss of mechanical properties and esthetic impairment. BASF‘s Irganox®, Irgafos® and Chimassorb® thermal stabilizers improve long-term thermal stability in building and construction applications.

 

Light stabilizers help to maintain the appearance and mechanical properties of plastic parts. BASF’s Tinuvin®, Chimassorb® and Uvinul® light stabilizers provide protection against degradation caused by exposure to heat, light, water, and other environmental factors.

Architectural Glazing

The requirements of the building industry for acrylic sheets call for high performance products.

BASF offers innovative solutions and effects to help meet these stringent requirements for stabilization and coloration of acrylic sheets.

Plastics used for architectural glazing applications are prone to the detrimental influence of heat and light, and must contain stabilizers to extend the lifetime of the product.

It is important to protect the very attractive properties such as color or transparency throughout the lifetime of the application, keeping performance and appearance of the acrylic sheets on a very high level as long as possible.

A continued trend in architectural glazing is the replacement of traditional glass applications by plastics such as :

  • polycarbonate (PC),
  • acrylics (PMMA),
  • polyesters (PET / PET-G)
  • and even polyvinyl chloride (PVC) for applications like canopies, signs and displays.

This trend is driven by a variety of factors including :

  • Flexibility in structural design,
  • Weight reduction,
  • and Safety (impact resistance, splintering).

Flooring Application

Due to the long lifetime expectancy of building and construction materials, light stabilizers are the most important effect additives for flooring applications.

For Polyolefin based flooring sheets, excellent weathering performance is achieved by combining Hindered Amine Light Stabilizers (HALS) and UV absorbers.

Geosynthetics

Ultraviolet (UV) light, heat and environmental exposure all play a role in the degradation of Polyolefin geomembranes.

Flexible Polyproplyene is susceptible to thermal degradation. Chemical additives are required to stabilize the polymers at ambient temperatures and inhibit molecular fracture.

Polyolefin geomembranes show enhanced light stability when stabilized with a combination of the UV absorber and a Hindered Amine Light Stabilizer (HALS).

Degradation of PVC membranes typically occurs as a result of plasticizer migration and high thermal exposure. Thermal exposure will break down the polymeric coating and release hydrogen chloride (HCL) that will assist in the degradation.

Pipes and Conduits

The processing and thermal stability of PEX pipes for hot water applications requires different solutions, depending upon the PEX production technology whether the cross-linking agent is a peroxide, a silane, or radiation induced.

BASF offers a variety of solutions for processing and thermal stability tailored to the stringent demands of the specific cross-linking technology.

Pigments can have an influence on the long-term heat stability of the polymer system as well as the processing stability of the pipe. It is essential to properly disperse the pigment to avoid a loss of the mechanical properties, for example, to avoid initiating crack and subsequent rapid crack propagation.

Depending on the application, other properties have to be taken into consideration, such as lightfastness, weather resistance and specific regulations such as food contact approval or National Sanitary Foundation (NSF) clearance in the U.S. for water pipes for instance. Market trends increasingly ask for heavy metal-free coloration systems and for higher performing, more weatherable and non-interacting colorants.

BASF has extensive experience in developing integrated solutions including color and additives for pipes.

Polymer, pipe and conduit manufacturers often operate under conditions of high shear and temperature, to improve the productivity of their process.

The efficient melt extrusion of highly viscous polyethylene for pipes and conduits requires high processing stability. The selection of the correct stabilizer system is crucial to ensure good processing stability during extrusion and sufficient thermal stability with respect to the expected lifetime of the pipe and conduit.

BASF’s tailored solutions for light stabilization help to prevent light-induced polymer degradation and also contribute to the thermal stability during outdoor storage as well as during any surface service life.

Most PVC based pipes and conduits are stabilized against the detrimental effects of light with TiO2 or carbon black.
For specific colored applications or in cases where the pipes or conduits cannot contain high levels of TiO2 or carbon black, superior light stability can be obtained using new systems based on the proprietary TINUVIN® X technology and formulations of this which include UV absorbers.

Public Seating

Whether in stadiums, arenas, schools, terraces and patios, restaurants or churches, public buildings, molded plastic furniture provides exceptional value because it is high quality, durable, ergonomic, light weight, portable, comfortable, easy to stack and store, and can be easily designed to match the latest trends.

Plastic furniture for indoor use is injection molded or blow molded in polypropylene or polyethylene as well as sometimes polyamide.

While it is true that virtually any desired color can be achieved using combinations of specific colorants, coloration of polymers typically requires consideration of many other characteristics at the same time.

By combining BASF colorants and expertise with our new light stabilizer solutions along with our expertise in these areas, we can help improve the durability and safety of outdoor plastic furniture.

With our products, you can manufacture high performance, long lasting, flame retardant stadium seats and other outdoor furniture.

Roofing

Plastic roofing membranes are widely used for waterproofing systems in domestic and industrial flat roof markets as well as pitched roofs.

Products that are currently used to protect PVC are titanium dioxide and UV absorbers.

The most common UV absorbers are from the hydroxybenzophenone or hydroxybenzotriazole class.

Plastic roofing membranes are widely used for waterproofing systems in domestic and industrial flat roof markets as well as pitched roofs.

TPO roofing membranes should contain a process stabilizer to protect the membrane during extrusion or calendering, and UV stabilizer and a thermal stabilizer to protect the membrane from heat and light degradation.

UV stabilizers that provide the most protection are combinations of low molecular weight and high molecular weight HALS.

Windows profile, siding and fencing

Solutions exist today to overcome historic PP drawbacks such as loss of gloss and chalking under weathering.

The use of PP in profiles enables more visually appealing plastic parts.

The use of PP as a material to produce profiles is rapidly growing, and offers significant improvement in impact strength even at low temperature and easier to recycle – Less sensitive to moisture.

Most PVC profiles are stabilized against the detrimental effects of light exposure thanks to high loadings of Ti02.

For specific colored applications or in cases where the profiles cannot contain high levels of Ti02, light stability improvements can be obtained with new systems based on the proprietary Tinuvin® XT technology combined with efficient UV absorbers.

In the traditional, mass coloration of PVC, BASF has always had a leading and innovative contribution.

BASF develops answers and solutions, and via extensive experience can offer a wide scope for solutions.

Today, capstocks (film or co-extruded) are gaining in importance due their superior scratch resistance, chemical resistance, weather resistance, and ability to offer a more vibrant and versatile color palette.

Understanding the two main production processes enables BASF to tailor the offering to your needs. Keeping track of the ever evolving needs and trends of our customers and the market, cooperating with the industry and focusing on bringing value added solutions has enabled BASF to propose outstanding solutions for the windows, siding and fences market.

Wood Replacements

Wood plastic composites contain typically anywhere from 30% to 60% wood fibers and 70% to 40% plastic.
They are usually very rigid and often are pigmented to look like natural wood. Sometimes they are also foamed, i.e. air is added during processing to reduce the weight of the final article.
All of these end uses require that the wood plastic composite be properly stabilized against the harmful effects of UV exposure.
Continued exposure of wood plastic composites to sunlight may result in loss of initial color and loss of initial properties (such as tensile and impact properties).
Coloration of the wood plastic composites is determined by the plastic substrate that is used such as Polyethylene (HDPE), Polypropylene (PP) or PVC.
Techniques are emerging that allow more homogeneous coloration of both the wood flour and plastic substrate.
However, the large variation of the nature and self-coloration of wood flour calls for customized coloring solutions.
