FRP-950X series is a flame retardant masterbatch with ultra-high red phosphorus content, mainly
consisting of microencapsulated red phosphorus. Because of the high red phosphorus content, the
additive volume in the plastic product is extremely small. Only 5%-9% flame retardant is added in
the polyamide composite material, the flame retardance can be up to UL94-V0 (T2.0mm).
1. High efficiency
Because of the high content of red phosphorus, low dosage adding will achieve high flame
retardancy. For example, adding 5%-7% FRP-950 to PE, the flame retardancy will be V-0 at 2.0mm
according to UL-94.
2. Excellent mechanical property
Due to the low dosage needed to achieve UL-94 V0 grade (approx. 4.8-7.2% by weight as pure red
phosphorus), they show low impact on mechanical properties.
3. New carrier
We use a new type compatilizer as the carrier for microencapsulated red phosphorus, this is our
exclusive technology in China.
4. Extra small powder.
The average red phosphorus grain size is about 2000 meshes.
5. Ecological friendly: Non-halogen, reach RoHS and REACH requirement.
6. Low moisture absorption.
7. Easy handling.
8. Very low migration and glooming.
9. Can be used for printed circuit board.
