Step-by-step solution
Nylon 6 or polycaprolactam is a polymer, in particular semicrystalline polyamide. Vulcanization is a chemical process in which the rubber is heated with sulphur, accelerator and activator at 140 – 160 ° C . The process involves the formation of cross-links between long rubber molecules to achieve improved elasticity, resilience, tensile strength, viscosity, hardness and weather resistance. Polychloroprene is the polymer name for the synthetic rubber known as neoprene. Natural rubber is the only addition
