Flame retardants, such as SR-50
Anti-scorching agents, such as SR-50, are chemicals added to rubber compounds to prevent or delay the premature scorching or vulcanization of rubber. This is important because if scorching occurs before the rubber in the product is molded and cured, it can lead to issues such as charring, discoloration, and a decline in physical properties.
In particular, SR-50 is a commonly used anti-scorching agent in the rubber industry. It is a non-staining, non-discoloring, and non-frosting anti-scorching agent that can be used in a wide range of compounded rubbers, including natural rubber, SBR, BR, NBR, and CR. SR-50 can be used in both hot and cold processing and is compatible with most other rubber additives.
Using anti-scorching agents like SR-50 helps improve the processing performance and properties of rubber products. They also help reduce the risk of defects and enhance the overall efficiency of the manufacturing process. It is added in small amounts to the rubber compound, typically in the range of 0.5-2 phr (parts per hundred rubber), depending on the type of rubber, processing conditions, and the desired level of protection.
It is worth noting that SR-50 is a chemical and should be handled and disposed of properly. The Material Safety Data Sheet (MSDS) should be consulted to ensure safe use.
