Lehigh’s micronized rubber powder (MRP) is an ideal additive for plastic applications that require the inherent benefits of rubber, such as flexibility and durability. For example, polypropylene and polyethylene are two of the most widely used resins in applications ranging from industrial piping to consumer storage solutions to automotive components. Whether the application uses prime resins or blends with recycled polymers, including MRP in the compound provides a compelling value proposition, in terms of both economics and performance.
MRP is already used in a variety of plastics processes, including injection molding, compression molding, sheet extrusion, nylon systems and more.
Lehigh’s Zenoflex™ product range offers compounded masterbatch solutions for easy incorporation into existing manufacturing processes. By providing the MRP and plastic compound in pellet form, Lehigh eliminates the need for customers to handle micron-scale powders during operations.
For all applications, Lehigh collaborates closely with customers to design the right compound composition, performance targets and processing conditions to meet performance and cost requirements.
- Increased flexibility
- Increased durability
- Lower product cost
- Improved processing and product performance
- Increased sustainability of end product
- Attractive aesthetics and smooth surface finish
Lehigh chemists have worked with leading universities to understand the science of polymer-MRP interaction. This has helped us to design formulations that maximize the customer benefits of using MRP in plastics. We frequently publish our results in leading technical journals and present MRP technical presentations at major conferences around the world. In 2013, we published a peer-reviewed technical paper, "Effects of Micronized Rubber Powder on Structure and Properties of Polypropylene Composites." The paper, published in Waste and Biomass Valorization, examined the science of MRP-polymer interaction.
