FR-1420 is specially designed for polyolefins such as PP, PE and TPV. It is a halogen-free intumescent flame retardant with phosphorus and nitrogen as the main flame retardant elements (the system does not contain APP); it is mainly based on carbon formation and intumescent flame retardant mechanism Play a flame retardant effect. It is not restricted by RoHS and REACH; it has the characteristics of high flame retardant efficiency, good thermal stability, no precipitation, good water resistance, light aging resistance, low smoke and non-toxicity. FR-1420 flame-retardant PP, flame-retardant reaches UL94 V-0 (0.8mm), and has passed the 70℃*168 hours immersion test (UL746C), and also passed the GWIT900℃ and GWFI960℃ glow-wire test; FR-1420 can also Used in glass fiber reinforced PP, it can reach UL94 V-0 (0.8mm).
