WESTCO™ DETU is an ultra accelerator for CR, EPDM and chlorobutyl rubber; it is also used in latex as a primary WESTCO™ DCBS Accelerator WESTCO™ DCBS is a slow curing, delayed action accelerator especially useful in curing thick rubber parts.
- Which rubber accelerators are suitable for vulcanization?
- Western Reserve Chemical offers a full range of rubber accelerators to increase the speed of the vulcanization of rubber. We supply both primary and secondary accelerators that are suitable for both for natural rubber and synthetic rubber compounds including NR, CR, SBR, NBR, BR, EPDM and chlorobutyl rubber.
- Which accelerator is best for EPDM rubber?
- We used the accelerators; thiazole, sulfonamides, dithiocarbamate, thiuram, and guanidine groups. The results show that the fastest cure time and the best tensile strength are achieved with dithiocarbamates for EPDM rubber. The effect of accelerators in EPDM mixtures on the value of ML.
- How do manufacturers protect EPDM products from Blooming?
- To prevent blooming manufacturers will need to take steps to protect EPDM products. This will be either selecting an EPDM formulation that is especially resistant to blooming or using an accelerator blend in the process of manufacture.
- What are N-nitrosamines in EPDM vulcanization?
- N-nitrosamines. of EPDM, synthetic diene rubbers and natural rubber. During vulcanization, it does not form any secondary amines which can be converted to N-nitrosamines. conventional types of rubber, especially EPDM. Accelerator systems for EPDM rapid vulcanization. Due to very good processing safety, the green compounds have a good shelf life.
- What are the advantages of EPDM vulcanization?
- During vulcanization, it does not form any secondary amines which can be converted to N-nitrosamines. conventional types of rubber, especially EPDM. Accelerator systems for EPDM rapid vulcanization. Due to very good processing safety, the green compounds have a good shelf life. excellent reversion and heat ageing resistance.
- Can deovulc EG pre blended accelerators be used in EPDM compounds?
- The use of Deovulc EG pre blended accelerators in EPDM compounds has been proved to offer practical and technological advantages compared to working with several individual accelerators.
