How Recycled Rubber Mats are Made: Devulcanization!

In order to make new products, rubber tires must have their rubber, metal, fabric, and other parts removed and separated. Recycled tire rubber is now prepped to be refined into crumb rubber or readied to be devulcanized. It can then be devulcanized, making them malleable enough to form into new rubber products, like recycled tire mats.
