2,5-Bis(t-butylperoxy)-2,5-dimethylhexane

Trade name: FARIDA DHBP
Common name: DHBP
Chemical name: 2,5-Bis(t-butylperoxy)-2,5-dimethylhexane

Formula: C₁₆H₃₄O₄
Chemical Structure:

Molecular Weight: 290

CAS NO: 78-63-7

Properties:

Activation energy : 36.0kcal/mol 　　

1min. Half life temp.: 192℃

Flash point: 36℃

SADT.: 80℃

Alarm temp.: 75℃

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.
