Microencapsulated red phosphorus flame retardant master batch

Product Description

Product features
 High efficiency
Because of the high content of red phosphorus (≥*0 %), small quantity adding will achieve high flame reatardancy. For example, adding 6%*9% FRP***0 to PA, the flame retardancy will be V*0 at 0.8mm according to UL**4, as well as achieving **0V CTI value.
 Exellent mechnical property
Due to the low dosage needed to achieve UL**4 V0 class (approx. 4.**7.2% by weight as pure red phosphorus), they show low impact on mechanical properties.
 New type carrier
We use a new type compatilizer as the carrier for microencapsulated red phosphorus, this is our exclusive technology in China.
 Extra fine powder
The average red phosphorus grain size is approxamaly *0 um.
 Eclogical friendly
Non-hologennated, reach SGS and RoSH requirments.
 Better flowability
 Low moisture absorption
 Easy handling
 Very low migration and glooming
 Can be used for printed circuit board.
