How Is 4-Methoxyphenol (MEHQ) Used as a Stabilizer in Polymer Systems?

Kaushal24 Feb, 2026Business

Learn how 4-Methoxyphenol (MEHQ) functions as an effective stabilizer in polymer systems by preventing unwanted free-radical polymerization in reactive monomers during manufacturing, storage, and transport. Acting as a phenolic inhibitor, MEHQ scavenges free radicals that trigger premature reactions, helping maintain product integrity and consistent quality across industrial polymer chains. This stabilizing action reduces risks such as heat build-up, fouling of equipment, and off-spec materials, improving safety and reliability in polymer production and handling. Professionals in coatings, adhesives, and speciality chemicals turn to MEHQ for controlled inhibition and better process outcomes.
