Application:

FARIDA DHBP is used as curing agent for silicone rubbers, polyurethane rubbers, ethylene-propylene rubbers and other kinds of rubbers, as well as crosslinking agent for polyethylene and curing agent for unsaturated polyether.

Compared with Di-tert-butyl peroxide and DCP, DHBP is less volatile and more stable. It is a very effective high temperature curing agent for vinylsiloxane rubbers with higher tensile strength and lower tensile stretch.

 

Package and Storage:     

Packed in PE drums, N.W.: 25kg.

Stored below 38℃.

Keep away from direct sunlight, strong acids, reductive agents and violent shaking during transportation or storage.
