Engineered Sheet Products™ (ESP™), a division of RTP Company, is your one-stop-shop for custom extruded sheet. As a result of our relationship with RTP Company, our services and capabilities range beyond what you’d expect from a typical sheet extrusion manufacturer because there is no need to compromise with an off-the-shelf material and/or sheet size.

Come to us with your material requirements and we’ll work with RTP Company’s Engineering Department to select an extrusion grade compound optimized to make your program a success. We work in many different engineered resin systems and offer a wide range of thermoplastic technologies, including:

Once a compound has been selected, we’ll further review your sheet sizing requirements. Our capabilities range from thick-gauged sheets for thermoforming and thin-gauged sheets for die-cutting, which makes us well equipped to help you optimize for high yield!
