11. The vulcanization of rubber is a thermosetting process. 12. Polymers of butadiene and isoprene had good elasticity after vulcanization , but were crumbly. 13. It is used in the vulcanization of rubber. 14. After vulcanization , before it is usable, the mold must undergo gating and venting. 15. In terms of vulcanization , the standard method for the old type is amine vulcanization. 16. In terms of vulcanization, the standard method for the old type is amine vulcanization . 17. ?1839 invention of rubber vulcanization . 18. Sulfenyl chlorides are used in the production of agents used in the vulcanization of rubber. 19. Ethylene thiourea is an excellent and proven accelerant of vulcanization of neoprene and polychloroprene rubbers. 20. If vulcanization goes on, Mooney viscosity becomes in many cases practically constant in time.
