Specification :

FR is a series of halogen-free flame retardant master batch containing red phosphorus and polymer resin, for applications in engineering thermoplastic, such as PA, PBT, and PPO etc.
FR is based on stabilized and micro-encapsulated fresh red phosphorus power grade and polymer as a carrier resin. It is offered as a non-dusting pellets form which make it easier to handle, accurate to dose and safe to process. It is easy to be homogenously dispersed in the polymer compound.
