MRP - PolyDyne
PolyDyne® ground rubber compound produced from end-of-life tires provides compound cost savings, lower cost compound options, reduced landfill costs and supports circular and sustainable materials use.
A Standard Raw Material
Lehigh’s PolyDyne® MRPs (micronized rubber powders) have been designed specifically for the tire, custom mixing and rubber industries. It has become a standard raw material for customers in these markets and an essential component of modern rubber compounding. To date, it has been used in the manufacture of more than 500+ million tires worldwide
PolyDyne® is currently used for the following applications:
