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. specification
