Delivering Performance at Lower Cost

Lehigh’s MRPs are an ideal additive for plastic applications that require the inherent benefits of rubber, such as flexibility and durability. Importantly, these benefits do not come at the cost of aesthetics – our micron-scale powders provide a smooth surface appearance on finished products. Adding Lehigh’s MicroDyne™ MRP into plastics saves money, can improve processing and product performance, and increases the sustainability of the end product.

Polypropylene and Polyethylene

Polypropylene and polyethylene are two of the most widely used resins found in applications ranging from industrial piping to consumer storage solutions to automotive components. Whether the application uses prime resins or blends with recycled polymers, MRP can help lower the part cost, increase throughput and may reduce energy consumption. Lehigh’s MRPs are used today in injection molding and compression molding applications.

Lehigh offers compounded masterbatch solutions for easy introduction to the manufacturing process. Formulated to meet the specific application and equipment requirements, these customized solutions avoid the need to handle micron-scale powders in a high-throughput molding operation.

Engineering Resins

Lehigh’s MRPs have also proven effective in nylon systems, as well as other engineering resins. For all applications, we collaborate closely with our customers to design the right compound composition and processing conditions to meet the performance and cost requirements.

MRP can also offer advantages for thermosetting polymers. For example, in polyurethanes, we have demonstrated lower cost and improved energy absorption characteristics.

Ongoing Research

We’ve worked with leading universities to understand the science of polymer-MRP interaction. This work has helped us to design formulations that maximize the customer benefits of using MRPs in plastics. We frequently publish our results in leading technical journals. In 2013, we published a technical paper entitled "Effects of Micronized Rubber Powder on Structure and Properties of Polypropylene Composites."


MRP Plastics Research

In 2013, Lehigh published a peer-reviewed technical paper examining the science of MRP-polymer interaction. This paper, entitled "Effects of Micronized Rubber Powder on Structure and Properties of Polypropylene Composites," was published in Waste and Biomass Valorization. Access the full paper here
