ADVANCING PERFORMANCE AND FLEXIBILITY
From residential homes to commercial buildings and from highways to railways, Sarlink® TPVs can be found in static and dynamic seals, boots, membranes, expansion joints, and any other building and construction products that require excellent long-term performance and shape retention. Sarlink® TPVs offer excellent abrasion, UV, and ozone resistance and remain flexible even at extreme temperatures, so seals won't crack over time.
Sarlink TPVs
- Excellent weatherability
- Matte finish with superior surface aesthetics
- Suitable for molding, extrusion, and co-extrusion
- High melt strength and a broad processing window
3100 Series: General Purpose TPVs
These general-purpose TPVs exhibit well-balanced flow characteristics yielding a superior surface appearance. Available from 35 Shore A to 45 Shore D (in black and natural), this Sarlink® series is partially cross-linked, offers excellent melt elasticity, and can be processed by injection or blow molding and extrusion.
3400 Series: TPVs for Potable Water (ANSI STD 61)
The Sarlink® 3400 Series was developed specifically for potable water applications and is certified to ANSI STD 61 for Drinking Water System Components in commercial hot water applications (up to 180oF). Per this certification, these grades are suitable for gaskets, liners, tubing, and hoses used for drinking water and beverage systems. The Sarlink® 3400 Series combines excellent flexibility with superior elastic properties to make high-performing seals and components. Sarlink® 3400 is available from 45 to 90 Shore A in natural and black.

5700 Series: High Performance Extrusion TPVs
Engineered for optimum extrusion performance, the Sarlink® 5700 Series exhibits excellent melt strength, with a very controlled morphology for a best-in-class surface appearance. These TPVs deliver superior UV resistance and exceptional color retention without blooming and are available from 25 Shore A to 50 Shore D in black only.
6100 Series: TPVs with Superior Colorability
The lighter, natural color of the Sarlink® 6100 Series allows for superior colorability versus other TPVs. These products exhibit excellent flow behavior for molding large complex parts and are non-hygroscopic, so pre-drying is unnecessary. The Sarlink® 6100 series is available from 35 to 90 Shore A (in natural only), is resistant to hydrocarbons and aqueous liquids, and exhibits good thermal stability and low fogging properties.
8100 Series: Extrusion Foamable TPVs
Sarlink TPVs are used extensively in sealing applications, and for lower cost, lighter weight seals, TPVs can be foamed. The Sarlink 8100 Series of TPVs are specifically formulated with optimized rheological properties for foaming. Available from 45 to 68 Shore A, these grades can be be co-extruded with other TPVs, TPOs, or PP. The Sarlink 8100 Series of TPV s offer long term sealabiltiy, low-temperature flexibility, and can be heat welded. Using either physical or chemical blowing agents, achieve up to 40% weight reduction for extruded profiles, seals and gaskets for doors and windows, drum seals, and HVAC applications.
RX 3100B Series: TPVs with up to 40% Recycled Content
By incorporating up to 40% post-industrial recyclate (PIR), depending on hardness, the Sarlink® RX 3100B Series promotes a circular economy and reduces reliance on virgin fossil-based resources and energy. Made with carefully-selected post-industrial recyclate (PIR), these materials process and perform similarly to their virgin counterparts, and can be used in injection molding or extrusion applications, or can be co-molded or co-extruded with polypropylene or other thermoplastic elastomers (TPEs).
