Ceramicized Refractory Low Smoke and Halogen Free Flame Retardant Polyolefin

Ceramicized refractory polyolefin has low smoke, no halogen flame retardant properties, in 350-1600 ℃ with flame, without flame, can be sintered into a hard ceramic armor does not melt, do not drip, do not fall off, will not cause secondary fire, ceramic body in the sintering process to play a very good fire insulation, to prevent the further spread of flame.

Material advantages
1、Excellent heat insulation and temperature isolation performance: after ablation, the cross section will generate uniform microporous ceramics, which can play a very good heat insulation, temperature isolation and fire blocking effect.
2, excellent flame retardancy and fire resistance: in the fire burning crust fast, hard, dense, while having a certain degree of flame retardancy, oxygen = index greater than 38
3、Excellent insulation performance
4、High and low temperature resistance: It can be used for a long time under the temperature of -60~150℃.
5, environmental performance: with low smoke halogen-free, non-toxic, in line with reach and rosh requirements;
