China (Mainland)
Major applacation
*PA6 and PA66, with or without glass fiber, with or without flexibilizer, recommanded adding 6%-9%
*PBT, with or without glass fiber, recommanded adding 8%-9%
*PP and PE, recommanded adding 8%-10%, plus 10% magnesium hydroxide
Possible applacation
PET, HIPS, TPU, PPO, PC, Silastic
Product features
l High efficiency
Because of the high content of red phosphorus (≥80 %), small quantity adding will achieve high flame reatardancy. For example, adding 6%-9% FRP-950 to PA, the flame retardancy will be V-0 at 0.8mm according to UL-94, as well as achieving 600V CTI value.
l Exellent mechnical property
Due to the low dosage needed to achieve UL-94 V0 class (approx. 4.8-7.2% by weight as pure red phosphorus), they show low impact on mechanical properties.
l New type carrier
We use a new type compatilizer as the carrier for microencapsulated red phosphorus, this is our exclusive technology in China.
l Extra fine powder
The average red phosphorus grain size is approxamaly 10 um.
l Eclogical friendly
Non-hologennated, reach SGS and RoSH requirments.
l Better flowability
l Low moisture absorption
l Easy handling
l Very low migration and glooming
l Can be used for printed circuit board.
