-Features: comparing to traditional red phosphorus fire retardant, LYFR300P has the advantages of high anti-flaming performance, light tone, excellent thermal stability etc.; comparing to halogen fire retardant, it comes in low density, high physical & mechanical performance, high CTI, no frost, no migration, and no corrosion to mould.
-Scope of application: applicable to polymers such as PA6, PA66, PBT, PC, PP, PE, EVA. When used for polyolefin plastic (PP, PE, EVA), it is recommended to be used in combination with aluminium hydroxide or magnesium hydroxide.
-Suggested adding proportion: 12-15%
