2-ethylhexyl thioglycolate

2-Ethylhexyl thioglycolate (CAS 7659-86-1 ), commonly abbreviated as EHTG and also known commercially as 2-ethylhexyl mercaptoacetate, is a sulfur-functional ester used as a reactive intermediate. It serves as a processing aid across polymer and rubber manufacturing. Its thiol group enables controlled reactivity in curing, chain transfer, and stabilization processes for various industrial applications. In PVC and vinyl polymer processing, EHTG functions as a co-stabilizer component and plasticizing modifier. This helps formulators balance flexibility and thermal stability in finished compounds. Rubber compounders use it as a crosslinking agent and vulcanization modifier. It is particularly useful where precise control over cure rate and network density is required for the material. In polymer synthesis, EHTG acts as a chain transfer agent. This allows manufacturers to regulate molecular weight distribution during free-radical polymerization to meet specific performance criteria. Metalworking and lubricant formulators incorporate it as a reactive sulfur additive. It is commonly found in extreme-pressure and anti-wear packages for high-performance industrial lubricants. 2-Ethylhexyl thioglycolate is supplied as a clear liquid in standard industrial drum and IBC quantities. Technical grade is the primary commercial specification available to industrial buyers. Purity levels typically range from 95% to 99% for this chemical. Documentation including COA and purity assay results are standard for procurement and quality assurance purposes. Contact us for supply of 2-ethylhexyl thioglycolate Request Quote
