WINONA, Minn.— RTP Company recently reported that it acquired the Zeotherm® TPV product line from Zeon Chemicals. The transaction, completed in May of 2019, encompasses all products sold globally under the Zeotherm TPV name.

“This acquisition is just the latest step in our rapidly expanding Thermoplastic Elastomer business,” said Todd Gummersbach, general manager, TPEs, at RTP Company, in a company release. “The Zeotherm TPVs expand our product line, which includes compounds based on SEBS, TPV, TPU, POE, COPE, and COPA, making it one of the broadest TPE product portfolios in the industry.”

Zeotherm TPV products are complex and diverse formulations that are available in durometers ranging from 70A through 40D. The material offers continuous use performance at 150° C (302° F) while withstanding long-term exposure to engine oils and lubricant greases, a level that cannot be achieved with other TPEs or copolyesters, according to RTP.  Zeotherm TPV is also said to bond well to nylon substrates in overmolding applications.

“This TPV technology, along with RTP Company’s Nylabond® products, offers customers a full range of nylon-based TPV options that can be customized to fit the precise requirements of an application,” said Gummersbach. “For design engineers with applications that require high performance in potentially harsh environments, such as under-the-hood automotive parts or harsh industrial applications, Zeotherm TPVs can be an excellent material choice.”

RTP Company (www.rtpcompany.com), headquartered in Winona, Minnesota, is a global compounder of custom engineered thermoplastics. According to the company, its engineers develop customized thermoplastic compounds in more than 60 different engineering resin systems. The compounds are used for applications that require color, as well as conductive, elastomeric, flame retardant, high temperature, structural, and wear-resistant properties.
