Polyurethanes – A thermal efficient all-arounder!


The simple processing of a liquid reaction mixture means polyurethanes can be expanded to fill a large range of products at virtually any given shape. This “made-to-measure insulant” boasts extremely low thermal conductivity levels matched by no other conventional insulant. Good mechanical properties and excellent adhesion mean the material has a wide range of applications.


BASF plc is the leading UK supply for rigid insulation materials and offers PU product solutions to customers in a wide range of industries:
 
PU insulated components for coldchains:
  • Plug-in cooling systems

  • Doors, cooling cabinets, cold rooms

  • For industrial end users within the cooling chain such as food manufacturers, restaurants and other industries (e.g. medical facilities)

  • Singular cooling elements, partition walls

  • Clean rooms and clean room warehouses

 

PU insulated construction components:

  • Clinker facade elements

  • Portable cabins / buildings

  • Partition walls

  • Ceiling panels for cooling

  • Clean room panels

  • Sectional gates, rolling and folding gates

  • Profiles (e.g. window profiles)

  • Rolling shutter boxes

  • Shower trayers

  • Bathroom components

Elastopor®  H - The right choice for Structural Insulation Panels (SIPS)

SIPS are produced with polyurethane insulation foam sandwiched between Oriented Strand Board (OSB).

BASF offers ZERO ODP and low GWP polyurethane systems achieving U-values of 0.17-0.18 W/m2K using a 150mm thick panel. Lower U values are also possible by increasing the  panel thickness.

Key advantages of SIPS:

  • Wide range of structural usages

  • Benchmark thermal efficiency

  • Off-site manufacture reduces construction time on-site

  • Fast build times

  • High design flexibility

  • Less waste on-site

SIPS panels are normally produced in a horizontal heated press. The OSB facing material is pre-set into a restraining foaming jig which is then clamped by a press. Foam is then injected into the cavity between the two OSB faces. Injection time depends on a number of variables but is typically between 5 and 30 seconds. Immediately after the injection cycle the foam starts to react and expand flowing through the cavity to reach a complete fill in around 2 minutes. An initial curing period of around 30 minutes (depending on panel thickness) is required before the SIPS panels has sufficient strength to be released from the press. At this stage the panel can be stacked and stored as appropriate in preparation for shipment to site.
