PE is a thermoplastic resin produced by the polymerization of ethylene. It is non-toxic and odorless. It has excellent low temperature resistance, good chemical stability, and is not afraid of most acids and bases. We add PE plastic to the flame retardant masterbatch designed and produced by PE drawing process. It has the advantages of less material cost, excellent thermal stability and high flame retardant efficiency. It is especially suitable for PE film, wire drawing, Christmas tree, etc. . Next, Dowell will share with you the flame retardant mechanism of PE wire drawing flame retardant.

The flame retardant mechanism of PE wire drawing flame retardant is generally composed of three parts, namely: 1. acid source: providing the acid required for the esterification reaction; 2. carbon source: providing the hydroxyl group or other groups required for the esterification reaction Mass of material; 3. Gas source: Provide the gas needed for system expansion and foaming. They are a carbon layer formed by melting during the esterification reaction, and finally a porous foam carbon layer is formed to prevent the combustion from continuing. Different PEs with the same fraction of flame retardant will also have differences in flame retardant effect, because of the different PE olefin content and activity, generally choose PE between 335-450 degrees and flame retardant with decomposition temperature of 260 degrees Agent is best. Under this premise, the flame retardant effect of the produced PE wire drawing flame retardant is the best, and it is recommended to be used in the fields of building safety nets, tents, woven fabrics and civil fabrics.
