Plastics…it may not be the first thing that comes to mind when you think of Lehigh’s micronized rubber powder (MRP), but adding Lehigh Technologies’ MicroDyne™ into plastics saves money, improves processing and product performance, and increases the sustainability factor of the end product. Lehigh’s MRPs are a great additive for plastic applications that need the additional inherent benefits of rubber, such as flexibility and durability. And, because MRPs are of micron scale they provide a smooth surface appearance on finished products.
Lehigh’s MRPs have been found to work effectively in polyurethanes (foam, cast, spray, and thermoplastic), polyethylene, polypropylene, Nylon-6 and Nylon-6,6, and thermoplastic elastomers – just to name a few. What’s more, our MRPs work with recycled plastics, helping to “upcycle” plastics to prime levels, helping improve the overall quality of the sustainble product.
When used with plastic compounds, Lehigh’s MRPs act as a sound dampener, vibration deadener, and thermal insulator. In flooring, they help with anti-slip and anti-fatigue. MRPs do all of this at a lower cost than the materials they are replacing.
Lehigh offers a range of micronized particle sizes to fit any plastic application – from 400 microns (40 mesh) to 50 microns (300 mesh). Click here to view the MicroDyne™ product specification sheet, which includes the ASTM specification classification.
Lehigh Technologies is working with leading universities to understand how to maximize the use of MRPs in plastics to help companies save money, increase product performance and make their products more sustainable. Recently, Lehigh Technologies collaborated with Georgia Tech on the paper titled "Effects of Micronized Rubber Powder on Structure and Properties of Polypropylene Composites."
