In the thermoplastic FR rating test according to UL94 V1 and V0, the cotton indicator should not be ignited by the flaming particles and drops. In the industry PTFE fine powder is typically used in the FR formulations to improve the anti-dripping property. However the virgin PTFE fine powder is hard to handle in the process and agglomerated PTEF wil have dispersing problem in the compounding process. Bad dispersed PTEF causes inconsistent flame retardance performance and rough surface of molded parts.
Shinepoly® Anti-dripping Agent is encapsulated PTFE made with optimized fluoropolymer resin and through patented in situ polymerization. Optimized shell material of shinepoly anti-dripping agent offers excellent dispersion in various thermopoastic to make high quality molded parts, such as PC, PA, PPO, PBT, ABS, HIPS, PP and alloys.
