Polyisocyanurate boards (also known as PIR or polyiso) and rigid polyurethane foam are highly durable and best-in-class options for thermal insulation in the construction industry and in appliances. Because of increasingly stringent energy standards and trends towards a sustainable approach to energy use, these products have experienced considerable growth in recent years. With excellent R-values and ease of installation, polyiso boards and rigid polyurethane foam are in fact key drivers of energy efficiency in many applications.
Rigid foam insulation based on polyurethane chemistry can be found in the following areas:
- Commercial roof systems (polyiso boardstock)
- Commercial buildings (structural insulated panels, metal-faced panels, spray foam)
- Residential walls insulation (spray foam, sheathing)
- Appliances such water heaters, domestic refrigeration products and commercial refrigeration (rigid polyurethane foam).
As a leading producer of polymeric MDI (PMDI) in North America, BASF has been supporting manufacturers of polyiso boards and rigid foam insulation since these technologies first emerged. Today, with the growing need for energy efficient solutions, BASF recognizes the importance of a stable supply of polyurethane raw materials and ongoing technical support to further support the growth of our customers. As a result, we are is investing in PMDI capacity at our Verbund facility in Geismar, LA, and are continuously developing the expertise of our technical teams regionally and globally.
