Action of heat stabilizers and PVC flame retardant rubber compound of the conveyor belt

 Heat stabilizer is an important class of plastics processing aids , the birth and development of the PVC resin, heat stabilizer synchronization processing is mainly used for PVC resin , heat stabilizer and  WSD Chrolinated polyethylene so PVC resin , the ratio of hard and soft PVC products are a close relationship.
Also known as flame retardant agents, flame retardants or flame retardants : flammable polymer flame resistance conferred functional additives ; By Application divided into additive flame retardant and reactive flame retardant . According to the composition , including adding an WSD chromium oxide  inorganic flame retardant , halogen -based flame retardant ( organic bromides and organic chlorides ) , phosphorus-based flame retardants ( red phosphorus, phosphate esters , and halogenated phosphates , etc.) and nitrogen flame retardants .

Thermal stabilizers in PVC conveyor gum base resin is mainly used to improve the thermal stability of PVC resin in the processing and use , to extend the service life of the article . Such additives include tribasic lead sulfate , barium cadmium zinc liquid stabilizer . The flame retardant effect of the polymer material in the ignition of the flame spread rapidly Buzhi Yu , suppressing flames and heat from the WSD stearic acid  air. Such as antimony trioxide , zinc borate , aluminum hydroxide and the like. Both formulations have a different action can be selected according to the rubber compound formulation conveyor specific purposes.
