Properties:A white rhombus crystal, insoluble in water, dissolving in alcohol, ether, benzene, cumene and other organic solvents. Sublimable in high vacuum. Mainly decomposing into acetophenone and dimethyl carbinol. Active oxygen content: 5.8%. Decomposing temp.:120 . Half-life period: 1 min. when temp. is 180 ; 1 hr. when temp. is 135 ; 10 hrs. when temp. is 116 .
Usage:As an excellent organic peroxide, DCP may serve as initiator for polymerization, a vulcanizing agent, a cross-linking agent, or a solidifying agent, all of which have been found extensively applied to the manufacturing of macro-molecular materials such as rubberwares, polyolefin and foamed plastics. And all these materials are extremely useful in PE cable insulating/EPS and shoe-making industries etc. It is also a suitable additive for flame-retarding coatings.
