- What is a curing agent for vulcanization?
- curing agent of the sulphurless or low sulphur vulcanization. natural and sythetic rubbers. In combination with mercapto and sulphenamide accelerator. thiuram accelerators. The vulcanisates are then characterized by exceptionally good resistance to ageing. the rubber. In this way, optimal activity of the effective substance is assured.
- What is the function of mercapto sulphenamide in rubber vulcanization?
- It also functions as sulfur donor for vulcanization with low or no free sulfur. It causes very rapid and scorch-safe vulcanization of rubber along with good processing safety. It acts as activating secondary accelerator, when combine with other mercapto- or sulphenamide-type-accelerators.
- What is accelerator DPTT?
- Accelerator DPTT is a non-discoloring and non-staining accelerator. It is a very active sulfur-bearing accelerator and contains approximately 25% available sulfur. DPTT imparts unusually good heat resistance to sulfurless compounds and may be used as a primary accelerator for Hypalon and Butyl as well as an excellent secondary accelerator for EPDM.
- What is DPTT used for?
- DPTT imparts unusually good heat resistance to sulfurless compounds and may be used as a primary accelerator for Hypalon and Butyl as well as an excellent secondary accelerator for EPDM. It can also be used as a vulcanizing agent for heat resistant latex.
- What is Westco TM DPTT used for?
- Westco TM DPTT is used as the primary or secondary accelerator in natural and synthetic elastomers and as a sulfur donor in low sulfur or sulfur-less cures. It is suitable for use in light colored vulcanizates and provides better processing safety and heat stability than other thiurams. WESTCO ™ DPTT is packaged in 25 kg bags.
- What is vulcanization with vulcuren®?
- The heat stability of passenger tire tread compounds with Vulcuren® can be improved in comparison to compounds with a standard curing system. Vulcanization with Vulcuren® shows fast curing and a stable plateau. Physical as well as viscoelastic properties of the vulcanizates can be easily achieved.
