　　Anti-ozone agent for chloroprene rubber, chlorosulfonated polyethylene rubber, chloroether rubber, styrene butadiene rubber, and nitrile rubber. In chloroprene rubber, it can improve the heat resistance of the rubber compound, reduce the discoloration of the rubber compound in the sun, and have a slight slowing effect on vulcanization. It is also a heat stabilizer in chlorosulfonated polyethylene compounds vulcanized with metal oxides. This product has a good protective effect on ozone and weathering cracking and flexing cracking in styrene butadiene rubber, but it has no anti-oxidation effect. It needs to be used together with an excellent antioxidant. This product is easy to disperse in the rubber, which can make the rubber green, but does not pollute. The general dosage is 1-2 parts in chloroprene rubber and 0.5-3 parts in styrene butadiene rubber.

Packing: paper drum lined with PVC film bag 25kg.
