Technical indicators:

usage:Also called PDM or HVA - 2, multi-functional rubber additives, can be used in the process of rubber processing as vulcanizing agent, also can make peroxide system helps the vulcanizing agent, also can make antiscorching agent and tackifier, applies to general-purpose rubber, also applies to special rubber and rubber and system.

Cooperate with sulfur in natural rubber, can prevent sulfide to return the original and improved heat resistance, reduce the heat generated, ageing resistance.

Improve rubber and cord adhesion force and sulfide film.

Used in truck tire shoulder gum, rubber cushion layer.

Can solve the problem of oblique load tire shoulder empty.

Can also be used for large size thick products of natural rubber.

In chloroprene rubber, chlorosulfonated polyethylene rubber, styrene-butadiene rubber, nitrile rubber, isoprene rubber, butyl rubber brominated butyl rubber, acrylate rubber, silicone rubber and rubber and rubber and other special rubber, as auxiliary vulcanizing agent, crosslinking performance can be improved significantly, improve the heat resistance, is suitable for the high temperature fluidization system.

Reduce the compression permanent deformation is very obvious.
