PусскийAntiscorch agents, such as SR-50, are chemicals that are added to rubber compounds to prevent or delay the premature curing or vulcanization of the rubber. This is important because if vulcanization occurs before the rubber is shaped and cured in the final product, it can lead to problems such as scorching, discoloration, and reduced physical properties.
SR-50, in particular, is a type of antiscorch agent that is commonly used in the rubber industry. It is a non-staining, non-discoloring, and non-blooming antiscorch agent that can be used in a wide range of rubber compounds, including natural rubber, SBR, BR, NBR, and CR. SR-50 can be used in both hot and cold processing, and it is also compatible with most other rubber chemicals.
The use of antiscorch agents like SR-50 can help to improve the processing and final properties of rubber products. They can also help to reduce the risk of defects and improve the overall efficiency of the manufacturing process. It is added in small amounts to the rubber compounds, usually 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's worth noting that SR-50 is a chemical and proper handling and disposal should be considered, and a Material Safety Data Sheet (MSDS) should be consulted to ensure safe use.
