mixed peroxide-sulfur rubber curing system at guatemala
Mixed peroxide-sulfur rubber curing system. - Free Online
A mixed curing system can improve some rubber properties: adhesion to metal and nylon fibers (refs. 19 and 20); cut growth resistance and reduced heat build-up of a tread compound (refs. 7, 8, 21-24). The mechanism of peroxide-sulfur cure has been discussed in several publications (refs. 1, 6, 25-32).

Effect of vulcanization systems on properties
The sulfur cured system showed superior mechanical properties in terms of tensile strength, elongation at break and tension set compared to the peroxide system due to the PP degradation during dynamic vulcanization. A mixed curing system of peroxide and sulfur gave superior mechanical properties to peroxide or sulfur alone . However, TPVs containing sulfur curing agent always give an unpleasant strong smell during the fabrication process.

Cure Systems For Epdm Rubber Engineering Essay
Rubber vulcanised by sulphur cure system can accommodate more stress and exhibit higher elongation at break, while the advantage of peroxide cure over sulphur cure is the formation of thermo-stable carbon-carbon bonds instead of thermo-labile sulphur-sulphur bonds, as the dissociation temperature and energy of sulphur-sulphur bonds is lower than that of carbon-carbon bonds [17, 26].
