Chandra and Pillai [28] used a low-molecular-weight recycled rubber as a processing aid in a number of tyre tread formulations and compared its performance with other commercial process aids. This process aid (Ecoreen T) is shown to function as well as or even better than depolymerised NR or similar process aids. The same workers also reported on the use of new products with low viscosity that are produced by blending low-molecular-weight virgin polymers with recycled butyl rubber [29]. When these products... 

A number of new automotive rubber components are now on the market that contain a portion of recycled rubber. These include tyres, where around 5% can be found in the tread compound, and products in static applications that are used to insulate and seal. 

The BTRC recycled powder is used by companies to replace 40 phr of virgin NR in the tread of trailer tyres [8] and in all layers of solid tyres.
