What is rigid polyurethane foam

Rigid polyurethane foam (pur/pir) is one of the most efficient, high performance insulation material, enabling very effective energy savings with minimal occupation of space.About 50% of all polyurethane foam production is consumed by market demand for rigid polyurethane foam.Rigid polyurethane foam (rpuf) is a widely used engineering material.Its raw materials are generally presented in resin state.Polyurethane rigid foam is a new type of synthetic material with waterproof function.

While meps is not as resistant to water damage, xeps, polyurethane and polyiso rigid foam make effective barriers against moisture, although sometimes a facing.Highly resilient flexible foam seating.Polyurethane foam can be rigid or flexible and generally the foam structure is open, allowing for ventilation.The greatest advantage of pur foam is its excellent thermal insulation properties.This rigid polyurethane allows refrigerators and freezers to maintain the low temperatures necessary to preserve food.

How rigid foam insulation is used.This chapter is a partial compendium of blowing agents that have.Anpe is the sector of polyurethane rigid foam used for thermal insulation.
