Sarlink TPV Molded Glass Encapsulation

Sealing Systems

A vehicle's sealing system provides a flexible interface between the various components of the vehicle—be it metal, plastic, or glass—to prevent the passage of air, water, or noise into the cabin. Sarlink® continues to displace EPDM in sealing systems due to its lower density which yields lighter-weight parts, and faster, more efficient manufacturing. This leads to serious cost savings.

With first-class surface quality and weatherability, Sarlink® products remain consistent in gloss and color after long-term UV exposure. Sarlink® exhibits excellent adhesion to TPE or EPDM substrates with or without a slip coat, and select grades are designed for a lower coefficient of friction against glass or painted steel. With both TPE and TPV Sarlink® product offerings, Teknor can recommend the technology that best fits the application.

Sarlink TPV for Automotive Interiors

Interior

TPEs play an important role in automotive interiors, forming parts that protect the cabin from dirt, wear, and stains, while also providing a soft-touch feel to improve overall passenger comfort. The Sarlink® product line delivers superior performance in interior applications with excellent scratch and mar resistance, as well as protection against staining and cleaning solutions, and low fogging and VOCs. Sarlink® products exhibit excellent adhesion to polyolefins using multi-shot molding, providing a soft cushion to otherwise rigid parts.

Ultimately, Sarlink® delivers an ideal combination of haptics and aesthetics to meet your automotive interior needs. While Sarlink® TPVs exhibit a matte finish and rubber-like feel, Sarlink TPEs can be customized to have a glossy finish, and a satin-like feel. The TPE compounds can even be color-matched to create a consistent palette throughout the entire vehicle interior.

Sarlink TPV for Exterior Seals and Trim

Exterior

Automotive exteriors include static seals and molded or extruded trim that close the gaps between different parts of the vehicle and protect it from damage while improving the vehicle's aerodynamics. For automotive exteriors, the Sarlink® product line offers many valuable advantages, including a Class A surface appearance, excellent UV stability, and resistance to scratching and chipping. Furthermore, Sarlink® remains flexible and elastic at extreme temperatures and demonstrates outstanding long-term performance, ensuring a tight seal over time.

Teknor is unique in offering both TPV and styrenic TPE solutions for exterior molding and extrusion applications. Each technology offers distinct benefits: Sarlink® TPVs have improved chemical resistance, and are unaffected by OEM cleaning agents and waxes. Also, Sarlink® TPVs outperform competitive products in long-term performance. Sarlink® TPEs allow engineers more flexibility in designing parts. Lower in viscosity, Sarlink® TPEs can be molded into more complex, intricate geometries.
