Recycling of EPDM Rubber Waste Powder by Activation with liquid Polymers

摘要

The recycling of ethylene-propylene-diene-rubber (EPDM) waste was realized by activation of EPDM rubber waste particles surface with liquid EPDM polymers (LP) of low molecular weight. The optimal ratio of the waste EPDM rubber to LP was investigated whit regards to the original EPDM properties. The degree of unsaturated ethylidene norbornene diene ter-monomer in LPs plays an important role in the activation process and the cross-linking density of the reactivated materials and therefore the mechanical properties.
