- Which accelerator is most commonly used in rubber industry?
- most commonly used by the Rubber Industry.There is a wide variety o accelerators available to the compounder. For ease in understanding, it is useful to c assify accelerators by chemical structure. One such classifi ation, made by the ASTM s as follows: 1 Thiazoles (Me capto), 2. Sulfenami es, 3. Guani ines, 4. Dithiocarbamat
- What are accelerated elastomers?
- from a large number of organic compounds. These contain nitrogen or sulfur, or both. They have been developed over a period of many years and the type and amount depends on the elastomer used, the predetermined processing requ ments, and the anticipated curing rates. Accelerators are ty
- What elastomers are used in natural rubber?
- fferent elastomers on cure rate and state. Where a 50-part carbon black stock of natural rubber might use 2.25 parts of sulfur and 0.5 part of a sulfenamide accelerator, a similar SBR 1500 stock might use 1.75 parts of su
