Teknor Apex Co. has introduced its Sarlink ME-2600 Series, a styrenic thermoplastic elastomer injection molding compound that provides automotive manufacturers with processing and end use properties that the company said are superior to those of TPE-S materials currently used for window encapsulation.
The Sarlink ME-2600 Series includes 55-, 65-, and 75-Shore A compounds that have low specific gravities of 0.93 to 0.94, Teknor Apex said that is comparable to those of TPE-S grades now used in window encapsulation, but lower than those of PVC and EPDM, which typically exceed 1.10.
Compared to the existing TPE-S materials, the new Sarlink ME-2600 compounds provide higher flow, enhanced surface appearance, improved tensile properties, and greater stability upon heat aging and UV exposure, the company claimed.
Teknor Apex can manufacture the Sarlink ME-2600 compounds at its facilities in the U.S., Europe and Singapore. Sarlink ME-2600 compounds are being evaluated for rear side window encapsulation uses in 2016 models to be built in North America.
Based on proprietary styrene block copolymer chemistry, the Sarlink ME-2600 compounds are one of several new series of TPE-S elastomers added to the Sarlink product range, Teknor Apex said, which traditionally has consisted solely of thermoplastic vulcanizates. Other TPE-S series include high-performance and general-purpose extrusion compounds and injection molding grades for exterior trim, interior components, active grille shutters, and under-hood parts.
