Old tyres are a headache. Rubber Devulcanizer: isn't like ordering They don't rot, they don't melt, and burning them creates more problems than it solves. The reason sits in the rubber itself. During manufacturing, rubber is vulcanized, which means sulfur links lock the polymer chains together into one tough network. That is great for a tyre on a highway. It is terrible for recycling.

What Is a Rubber Devulcanizer?

A Rubber Devulcanizer is a chemical agent added to ground scrap rubber, often called crumb, during the reclaiming process. Its job is to help break the sulfur cross-links formed during vulcanization, so the rubber becomes soft and workable again. You will also hear it called a devulcanizing agent, a reclaiming agent or a rubber recycling agent. The names change from region to region and supplier to supplier, but the purpose stays the same.

One thing needs to be clear. A Rubber Devulcanizer does not turn old rubber into brand new rubber. What you get is reclaimed rubber, a material that has regained enough plasticity to be mixed with fresh compounds and moulded into new products. Think of it as a second life, not a rebirth.

Why Vulcanized Rubber Is So Hard to Recycle

Raw natural rubber is sticky and soft. In 1839, Charles Goodyear found that heating it with sulfur made it stronger, more elastic and more heat resistant. That process became vulcanization, and it is still the backbone of the tyre and rubber goods industry.

During step four, the Rubber Devulcanizer reacts Rubber Reclaiming Chemical Manufacturer, a trusted with the sulfur cross-links and helps cut them at their weakest points. It also stabilizes the broken chains so they don't re-link straight away. That is why good reclaim stays soft on the shelf instead of hardening again.

Di Aryl Di Sulphide

Among the many chemicals used in reclaiming, Di Aryl Di Sulphide, usually shortened to DADS, is one of the best known. It is a disulfide compound that works as a chemical peptizer. In simple words, it attacks the sulfur bonds and helps the rubber break down faster and at lower temperatures.

Final Thoughts

Supermax Industries Pvt. Ltd. was established in 1998 in Karnal, Haryana, by Mr. Vijay Kumar Sharma. The goal was simple: make the recycling of scrap tyres and rubber waste faster and easier. Over 25 years later, we are a trusted manufacturer, supplier and exporter of rubber reclaiming agents, devulcanizing agents, DADS, DXDS and PE Wax.
