Uses

1.This product is a polymerization regulator for synthetic rubber, synthetic resins, and synthetic fibers, particularly commonly used in the production of styrene-butadiene rubber and ABS resin. It reduces the branching degree of polymer chains and ensures uniform molecular weight distribution. It is often used as a nonionic surfactant and an intermediate in organic synthesis. It is employed in the manufacture of bactericides, insecticides, rust inhibitors, lubricant additives, pharmaceuticals, etc. It can also be used as "gold water" in the ceramic industry and as an acidizing agent in oil wells. Additionally, it serves as a stabilizer and antioxidant in the production of polyvinyl chloride, polyethylene, and polypropylene.
