Classification of Accelerators – Rubber Field Info
The chemical structures of these accelerators are shown in figure: Guanidines exhibit a slow vulcanization rate but are considered relatively safe accelerators for processing. They are not commonly used as primary accelerators due to their slow curing properties, although this characteristic can be advantageous when curing large-sectioned articles.

What temperature is soluble in rubber?
Data below refers toambient temperatures, as solubility of most rubber chemicals increases withtemperature, example S is soluble in NR or SBR up to ~ 1.2 PHR at 25oCbut at 93oC solubility of S increases to ~ 8 PHR. Based on commonformulations.
How does temperature affect a rubber compound?
to chemical attack are:1. Temperature f the Material Transmitted:Higher temperatures increase the effect of ch micals on rubber compounds. The increase varies with t e polymer and the chemical. A compound quite suitable at room temperature might fail very qui kl at higher temperatu es.2. Service Conditions:A rubber compound usually swells
