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.
