End-of-life tire rubber devulcanization by Maris

Since it was founded in 1962, Maris, a manufacturer of co-rotating twin-screw extruders, has claimed one of the leading positions in the research of new state-of-the-art applications for its products. With the aim of providing its customers with the widest range of choices, every mechanical component of Maris’ extruders are entirely in-house manufactured. Maris says it’s one of the few companies in the world able to customize its co-rotating twin-screw extruders according to its customers’ specific needs and this is true also when it comes to rubber devulcanization. Rubber devulcanization is a selective breaking process of an elastomer S-S and C-S bonds, which produces only a limited degradation of the polymeric structure (C-C bond).
