Who We Are

RTP Company is a global compounder of custom engineered thermoplastics. We formulate and manufacture thermoplastic pellets, sheet, and film with a wide range of special properties, such as strength, color, conductivity, elasticity, flame retardancy, and/or wear and friction resistance.  Our customers are injection molders and plastics processors; they melt our pellets down (or process our plastic sheet or film) to create thousands of products, from everyday toothbrushes and cell phones, to automobile and airplane parts, and even the most sensitive medical devices.

The Miller family established our corporate headquarters in Winona, Minnesota back in 1982. From the very start, RTP Company was built on strong family values and community involvement. We believe that every employee plays a part in the company’s success, and we believe in supporting the communities in which our employees live.

Today, we have over 20 manufacturing plants located in the United States, Mexico, Europe, Singapore, and China, and sales offices in major commerce centers around the world. Across the globe, our employees enjoy working together, and they share the same strong commitment to our customers: to provide them with the best possible thermoplastic solutions, as quickly and as accurately as possible.
