Thermoplastic elastomers (TPE) provide the properties of vulcanized rubber in a material with the processing ease and design flexibility of an injection moldable or extrudable product. Working with a variety of TPE polymers RTP Company can customize the chemistry to achieve specific hardnesses on the Shore A and D scale or other functional properties.

Growing in popularity for their ability add a soft-touch and more ergonomic feel to surfaces, TPEs have a long tradition as a workhorse gasket and seal solution for their flexibility. Shock absorption and vibration dampening properties are other hallmarks where TPE’s excel.

Often TPE’s are required to be overmolded onto a more solid substrate material using a multi-shot molding process, for these applications adhesion is critical. Selection of a TPE with the proper chemistry is important to achieve proper bonding, RTP Company has expertise in formulating both thermoplastic elastomer and rigid substrate products for this purpose.
