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 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.
