tert-Dodecyl mercaptan (TDM)

Tertiary Dodecyl Mercaptan

CAS# 25103-58-6

A highly efficient chain transfer agent widely used in free-radical polymerization processes. Its molecular structure allows precise control over polymer molecular weight and distribution, resulting in optimized polymer properties. It is valued for its effectiveness, stability, and ability to enhance process efficiency, making it a critical component in the manufacture of synthetic rubbers and latex products.

Uses of Tertiary Dodecyl Mercaptan

Essential in producing styrene-butadiene (SB) latex, SB rubber, and ABS resins. It adjusts molecular weight during polymerization, improving flexibility, processability, and mechanical properties of the final products. These materials are used in adhesives, tires, plastic alloys, and consumer goods, where high performance and durability are required.
