Antioxidant TMQ/RD (Polymerized 2,2,4-Trimethyl-1,2-Dihydroquinoline)

CAS Number: 26780-96-1

Polymerized 2,2,4-Trimethyl-1,2-dihydroquinoline (TMQ, also known as RD) is a classic non-staining antioxidant that provides excellent protection against heat aging and oxygen in rubber compounds. It is particularly effective as a thermal antioxidant in NR, SBR, and NBR compounds and is widely used in tire inner liners, inner tubes, and industrial rubber goods where non-blooming performance is needed.
