Cryogenic & nitrogen solutions for rubber and tire manufacturing

Air separation units (ASUs) play a vital role in rubber processing and tire manufacturing by supplying high-purity nitrogen and ultra-low temperature liquid nitrogen. Liquid nitrogen rapidly cools rubber to below its embrittlement temperature (down to -196 °C), enabling efficient cryogenic grinding and clean deflashing for scrap tire recycling. Additionally, high-pressure nitrogen provides a reliable, non-reactive environment for tire vulcanization and oxidation prevention. We deliver custom modular ASU solutions tailored for rubber recycling plants and tire manufacturing facilities worldwide.

Applications

Typical applications

Cryogenic rubber recycling & fine powder grinding: Using liquid nitrogen for ultra-low temperature freezing and ambient-to-fine rubber powder crushing.

Nitrogen vulcanization for tire production: Providing high-purity, high-pressure nitrogen gas as a stable inert medium for advanced tire curing/vulcanization.

Cryogenic deflashing & oxidation protection: Supplying liquid nitrogen for precise rubber molded part deflashing and nitrogen purging for raw rubber storage.
