TPE Window Trim

TPE Window Trim

The fastest growing market segment for TPE’s- Thermoplastic elastomers is automotive.

Formulation options and adhesion techniques for TPE’s give customers a wide array of options. In automotive door and window seals require strong UV resistance, flexibility, stable Shore-A and surface finish. This release covers a 2 component approach with EPDM.

Lightweight TPV

TPV is a vulcanized alloy of PP and EPDM and has excellent temperature and weathering properties. That’s the reason it’s been used so extensively in automotive. However, it is typically associated with higher cost compared to other TPE’s like SBC’s styrene-butadine compounds. With a specific gravity range up to 1.1 it’s not a natural choice if lightweighting or density/weight reduction is a priority. When Kureha introduced the S-Grade of microspheres the objective was to lower density without sacrificing control over surface finish or harndess. Low dose formulations are yielding specific gravity reductions in the .5 range with a Shore-A hardness above 50.

At this year’s Fakuma in Friedrichshafen, Kraiburg TPE debuted a new series of thermoplastic elastomers especially developed for excellent adhesion and UV resistance in two-component applications with ethylene propylene diene monomer rubber (EPDM).

Applications include EPDM window trim and seals.
