KIRYAT Gat, Israel (Feb. 3, 2009)—Israeli company Levgum Ltd. said it has developed a process using a proprietary modifier to devulcanize rubber goods.
The company says its technology is the brainchild of three scientists with wide experience in the rubber recycling and chemical fields.
The process involves adding Levgum's modifier to vulcanized rubber brought into a stressed condition at a two-roll mill for about 20 passes. This mechanical-chemical process, according to Levgum, is done at room temperature, doesn't use harmful chemicals nor produce or emit any hazardous waste or gases.
The firm said the process is completely environmentally safe.
Levgum said it wants to license the technology to rubber companies.
