Cross-linking is divided into radiation cross-linking and chemical cross-linking.
Chemical crosslinking. Triazole dimercaptoamine salt (FSH) is used for cross-linking. The cross-linking mechanism is that amines and sulfhydryl groups are combined to attack the carbon and chlorine polar bonds to perform substitution reactions. After cross-linking, the performance of the product, such as UV resistance, solvent resistance, temperature resistance, impact toughness, etc., will be comprehensively improved.
