EPDM tent to get the blooming problem comparing to other rubbers.
Generally vulcanization accelerator and other additives in EPDM are liable to bloom out to the surface, which cause various problems.
In order to solve this problem, STOPPER-EX is developed as a bloom preventer particularly for EPDM. STOPPER-EX has an excellent compatibility with the additives such as vulcanization accelerator to make them dispersed evenly. Then STOPPER-EX is cross-linked well and keeps the additives inside to prevent.
Appearance: White powder
Melting point: About 45-60
1.The bloom onto the surface of EPDM can be prevented
2.STOPPER-EX helps vulcanizing agent, vulcanization accelerator and other additives to disperse evenly.
3.Anti-Static electric effect can be obtained by adding STOPPER-EX
STOPPER-EX is mixed together with vulcanizing agent, vulcanization accelerator and other additives at 1-3% against the rubber.
