?Effect of flame retardant rubber o-rings

??Xin HuaXu rubber products company add flame retardant in rubber o-rings are the most commonly used method to improve the flame retardancy. Many different kinds of flame retardants, in accordance with the quantities of the flame retardant elements, can be divided into the halogen flame retardants, phosphate flame retardants, nitrogen flame retardants, phosphate - halogen flame retardant, phosphorus - nitrogen flame retardants, such as a few classes.

??Halogenous rubber o-rings, rubber with good flame retardancy, fluorine rubber oxygen index as high as 65% above, chloroprene rubber, chlorosulfonated polyethylene, chlorinated polyethylene is 25% - 32%, oxygen index was < 20% of flammable.

??Nonpolar hydrocarbon rubber lowest oxygen index, such as epdm oxygen index is only 20%, belong to flammable rubber.

??Inorganic flame retardant thermal stability is good. Flame retardant effect is increased with the increase of flame retardant, each kind of resistance agent when used alone, there is a minimum amount.

??Flame retardant rubber of rubber o-rings analysing choice should follow the following three principles:

??1. The rubber itself has a flame retardant;

??2. The burning heat is small;

??3. It has excellent high temperature and heat resistance.

??The body of the rubber o-rings of flame retardant rubber material selection more flame retardant, flame retardant resin, rubber, or both.

??For rubber o-rings vulcanization system, increase the crosslinking density can improve the oil resistance of vulcanized rubber. In the oxidation of fuel oil, used effective nitrile rubber vulcanization system of sulphur oxide or half, good oil resistance than sulphur vulcanization.

??Can choose rubber o-rings to xin HuaXu rubber products company, xin HuaXu o-rings professional manufacturers.?
