Rubber and EVE used crosslinking agent Dicumyl Peroxide DCP 99% Usually in end of July to end of August we do not export for hot weather. After crossing linking of DCP, the physical properties of polymer can be improved, for example, cross-linked PE improves its resistance to heat, chemical, pressure and cracking, and increase mechanical strength as well.
99% of purity and dicumyl peroxide (DCP) from Aldrich with minimum 98% of purity were used as received. 2.2. Grafting of MA to PHBV The grafting reaction of MA to PHBV chains was made by reactive processing in a torque rheometer (Haake 600). In this procedure, a mixture of PHBV and MA at the ratio of 90:10 (w/w) and 6% (w/w PHBV

In a first stage, at a temperature of 55 to 80° C., most of the CHP (97 to 99%) is decomposed and dicumyl peroxide (DCP) is produced from DMBA and CHP. In a second stage, acetone is added at a temperature from 80 to 146° C. to the obtained reaction mixture containing phenol, acetone, dimethylbenzyl alcohol (DMBA) and dicumyl peroxide (DCP).

The major factor affecting the rate of peroxide decomposition and, therefore, cure rate, is temperature. However, the polymer or medium in which the peroxide decomposes does have some effect on rate of peroxide decomposition. Di-Cup® dicumyl peroxide is much less sensitive to its environment than many other peroxides but
Retilox, through its continuous investment in R&D and pioneering the development of modified organic peroxides, offers special dicumyl peroxides grades, which substitutes the BIS peroxide with productivity above 30% in relation to the Conventional Bis, mainly eliminating the characteristic odor of the conventional dicumyl peroxide at 40% or 99%.
DCP was 99% pure peroxide, while PMTO was supported by a carrier in silica filler that is why it was 50% pure peroxide and 50% silica filler as a carrier. All of them were procured from Akzo Nobel, The …
groups at the polymer/solution interface.1 This system allowed us to relate the magnitude of "regime II" behavior with both the molecular weight between cross-links and the degree of surface modification.
