Rubber Compounder and Thermoplastics Materials Science

For over 75 years Minnesota Rubber and Plastics has been providing globally recognized materials science solutions to customers across a multitude of industries, including: medical devices, water, food, and beverage, transportation and more.

Materials science is at the heart of any new product we develop. Our elastomer compounds, Liquid Silicone Rubbers (LSR) or high-performance thermoplastics formulation chemistries are tailored to meet your exact requirements.

Superior Material Solutions – Simplified

When specifying a material for your application, there is a lot to consider. Temperature, environment, compatibility, hardness, compression, and certifications all have to be taken into account. We know this can be daunting. Our industry-leading materials science team is here to help with your compounding needs. The materials science team has a tool kit dedicated to helping find the best material fit for your application.

On-premise advanced materials lab saves time and costs

With our fully equipped materials lab, we’ll keep your projects on time and on budget. Any material can be developed, molded and tested in our state-of-the-art Materials R&D facility to allow you to sample multiple chemistries for your applications. R&D batches are closely monitored & measured and we ensure through our advanced mixing capability that any R&D material is readily scalable to a production setting.
