vulcanization and crosslinking in elastomers

Vulcanization and crosslinking in elastomers

Vulcanization agents include elemental sulfur (insoluble sulfur, colloidal sulfur) or an organic sulfur donor such as tetramethylthiuram disulfide (TMTD) or 4,4'-dithiobismorpholine (DTDM). The most important classes of accelerators are those based on sulfenamides, benzothiazoles, guanadines, and dithiocarbamic acid.

The MGO/ND complex (1.8 g, 2.0 g) and ZnC 4 H 6 O 4 ¡¤2H 2 O (1.35 g, 2.70 g, 4.05 g, 5.39 g) were dispersed in 40 ml of ethylene glycol under ultrasonic treatment. Based on the reaction yield (the yield can reach 80% in the case of excessive sodium hydroxide), 38 in our experiment, sodium hydroxide was excessive.

When applied to FKM, FKM antioxidant is generally not used, but a variety of anti-aging agents are used together. According to chemical structure classification, antioxidants can be divided into amines, phenols, sulfur, phosphorus and wax. Types and typical representatives of antioxidants are shown in Table 1.

Thermoplastic Elastomers (TPEs) and Thermoplastic Vulcanizates (TPVs)

Definition Thermoplastic vulcanizates (TPVs) are a very special class of thermoplastic elastomers prepared by dynamic vulcanization or cross-linking process, which involves the cross-linking of a rubber phase while it is being melt-mixed with a thermoplastic material at elevated temperature.
