CORAFOAM® U 280

CORAFOAM® U 280 is used as Polyurethane rigid foam PUR. can be cut with almost any type of tool. Its closed cellular structure and absence of fibers or granular structure result in crisp, excellently defined edges after fabrication. It is also impermeable by any type of liquid, including water and solvents, making it much better suited for severe weather conditions or harsh marine environments than many other materials.

Storage & Handling

Handling Notice

Terms "parallel" and "perpendicular" are referred to slab/specimen/block thickness direction. In some applications polyurethane may present fire risks, e.g. if exposed to fire or to excessive heat in presence of oxygen or air, including when welding or cutting with torches. It is the Customer's responsibility to determine if product described herein is appropriate for Customer's purposes and end-use and to ensure that working place, storage and disposal practices are in compliance with any applicable law
