Bergamid™ FR Non-Halogen Flame Retardant Formulations Versollan™ Thermoplastic Elastomers Hammerhead™ FR Flame Retardant Composite Panels

MAXXAM™ FR FLAME RETARDANT POLYOLEFIN FORMULATIONS are engineered to meet stringent flammability performance requirements.

These customizable formulations can replace traditional materials such as FR PC/ABS, FR PC/PET and FR COPE, offer improved chemical resistance to common disinfectants, achieve a UL 94 V-0 at 1.5 & V-1 at 0.75 flame rating when necessary, and can often be molded in existing PC/ABS tooling. Chemically resistant replacement for FR PC/ABS, FR PC/PET & FR COPE providing UL 94 Yellow Card V-0 flame rating at 1.5 mm, V-1 at 0.75 mm thicknesses for a broad color spectrum Outperforms FR PC/ABS, FR PC/PET and FR COPE in resistance to common disinfectants
