产品说明：
KYNAR FLEX® 2850-00 is a pelletized, semi-crystalline VF2 based copolymer. The powder form of this resin is designated KYNAR FLEX® 2851-00. KYNAR FLEX® 2850-00 has been specifically designed for use in wire and cable constructions which require an Underwriters Laboratories temperature of 150°C. It is close in physical performance to KYNAR® PVDF homopolymer grades, but has a higher flexibility. KYNAR FLEX® 2850-00 is also used in chemical applications as extruded sheet and pipe liners.
ADDITIONAL CHARACTERISTICS:
Excellent thermal stability
Excellent abrasion resistance
Excellent purity and chemical resistance
Impervious to UV degradation
Self extinguishing material
Extremely low smoke emission characteristics
Pigmentable
