Vulkanox TDQ (also known as TMQ) is a polymerized quinoline antioxidant used in rubber processing to provide protection against thermo-oxidative ageing during manufacturing and service life. It is chemically identified as 2,2,4-trimethyl-1,2-dihydroquinoline, polymerized. The product is supplied in yellow to brownish lentil-shaped granules, enabling ease of handling and uniform dispersion in rubber compounds.
Vulkanox TDQ is commonly incorporated in natural rubber (NR) and various synthetic rubber formulations where resistance to heat and oxygen exposure during processing is required. It is widely used in general rubber goods, tyres, automotive components, and industrial rubber parts. The material supports compound stability during mixing, storage, and vulcanization processes.
This product is supplied as per official manufacturer specifications. Technical and safety information should be reviewed before use in commercial formulations.
