TB-0056 — Chemical Resistance of Polyurethane Foams Technical Bulletin

Specific Chemical Resistance for Cut, Soil, and Flex LV PURe

The environments listed were selected because they represent different classes of chemicals which may be found in industrial waste water. The concentrations are more than likely severe compared with those that actually exist in the waste stream, but for comparison purposes, they represent an accelerated testing condition which allows for time reduction.

Time of exposure: 26 weeks
