Technical Datasheet | Supplied by ICL Industrial
FR-20-500 by ICL Industrial is a high purity magnesium hydroxide based on mineral raw material from the Dead Sea and special production technology. It is a non-halogen flame retardant with low smoke emission. During the decomposition process no toxic or corrosive gases are generated. In addition, it is an excellent smoke suppressant and acid scavenger. Its high thermal stability (up to 340°C) enables its use in high performance polymeric formulations. FR-20-500 is used in polyolefins, Polyamides, PVC and other thermoplastic polymers. Common end applications are wires and cables, injected molded articles for electronics and home appliances. FR-20-500 proprietary surface treatment insures excellent dispersion and superior mechanical and flame retardancy properties. It is also available in non-coated and other specialty grades which are suited for specific applications as well as in different particle size distribution and surface area (BET).
