- Properties: White powder. Relative density: 1.10. Soluble in acetone, ethanol, insoluble in water, hardly soluble in gasoline. Have hygroscopicity.
- Application: These enhancers to promote the effectiveness of anti-burning properties of low and poor, so for the second vinyl rubber has been rarely used, but in exceptional circumstances, such as thiuram sulfides with sulfur donor vulcanizing, etc., the goods with the activity the role of agent, thiourea type accelerator of vulcanization of the neoprene is a unique performance, can be obtained tensile strength, hardness, compression permanent deformation, such as good performance neoprene vulcanizate. This product with the NA-22 compared to scorch and curing are faster, but better flat vulcanization. Easily dispersed, do not emit cream. When the amount is large, it can be vulcanized at high temperature and high speed, especially for continuous vulcanization of pressed products. This product is also a accelerator for butyl rubber and a vulcanizing active agent for EPDM. It has antioxidant effect on NR, CR,NBR and SBR. Generally used for manufacturing industrial products, special wire, sponge products, etc.
Major Applications
Oil Seals and Gaskets:
TBBS is employed in the production of rubber seals and gaskets for applications where oil resistance and sealing properties are critical, such as in automotive engines.
Vibration Isolators:
In the field of machinery and equipment, TBBS can be used in the production of rubber components for vibration isolators, contributing to shock absorption and damping properties.
