applications
pfr-sn3020 can be used alone, or in combination with other flame retardants.
*epoxy resin sealant, 3l-fccl, ffc, rcc, pcb etc... which have a high requirement of
halogen-free, lead-free, anti-hydrolysis, non-volatile, non-migratory.
*special cable, melt adhesive, and some thin-walled narrow-section electronic materials,
which have a high requirement of good surface, good dispersity, natural color, halogen-free, anti-hydrolysis, non-volatile, non-migratory.
*tpe-e, sebs, eva, pet, pbt, etc... which have a requirement of good surface, good
dispersity, good touch, high temperature-resistant, anti-hydrolysis.
compatibility
pfr-sn3020 are compatible with melapur 200, px-200/230, fp-100/110, spb-100, sgb-100, ath, mdh etc..., which can improve the properties of electrical, mechanicalness,
heat-resistant.
