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
