Development of Automotive Rubber Parts with New Recycling Technology 2000-01-0015

Rubber is a thermosetting material and as such is generally considered difficult to recycle; therefore there is a demand for the development of rubber recycling technology to protect the environment and conserve resources. Some technologies exist to recycle vulcanized rubber, but none of these has high enough productivity to produce reclaimed rubber, and re-vulcanized rubber does not have the same properties as virgin rubber materials.

Now a new recycling technology, called Shear Flow Stage Reactor, has been developed for rubber reclamation. This new technology has high productivity and can achieve the same properties as virgin materials. Automotive parts have been developed and are being produced with recycled Ethylene-Propylene-diene Rubber (EPDM) based on this new technology. The performance of the developed parts is the same as the parts made from virgin materials. This new technology can be applied to other rubber materials, such as Natural Rubber (NR), NR/Styrene-butadiene rubber (SBR), and Butyl rubber (IIR) with appropriate reclaim conditions and will be an important new technology for rubber recycling.
