Advancing Performance and Flexibility

Thermoplastic Elastomers, or TPEs, are a premier choice for soft, flexible materials due to their robust properties, cost effectiveness, and design optionality. As a global leader in compounding, Teknor Apex offers one of the broadest portfolios of TPE technologies in the industry, including styrenic block copolymer (SBC) compounds, polyolefin blends (TPE-O or TPO), thermoplastic vulcanizates (TPE-Vs or TPVs), polyurethane compounds (TPE-U or TPU), and other specialty blends. 


Why Sarlink® TPVs & TPEs

Why Sarlink® TPVs & TPEs

Sarlink® thermoplastic vulcanizates (TPVs) are a premier solution for critical applications that require superior elasticity and long-term performance. With faster, more cost-effective processing, Sarlink® TPVs provide a sustainable alternative to thermoset rubber in sealing applications. In addition, the Sarlink® portfolio has recently expanded to include styrenic TPEs, which introduced unique performance characteristics, such as improved flow properties, to achieve more complex designs. Teknor Apex offers multiple chemistries under one brand, which enables us to provide a wide range of solutions for your applications.

Building & Construction

Building & Construction

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 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 are often more durable. Common applications include:

  • Drainage
  • Irrigation
  • HVAC
  • Air Distribution
  • Glazing
  • Structural Seals
  • Highways and Railways


Sarlink® TPVs are a premier choice for industrial products that require long-term performance in harsh environments, like seals, gaskets, and industrial hoses. Sarlink® has excellent resistance to flex fatigue, chemicals, and extreme temperatures. Sarlink® TPVs have displaced thermoset rubber in industrial applications, generally offering better long-term aging performance and increased design flexibility. Unlike rubber, Sarlink® can often be co-molded or co-extruded onto a rigid part to make the ultimate seal, eliminating the need for assembly. Typical applications include:

  • Pipe Seals
  • Foamed Drum Seals
  • Diaphragm Seals
  • Gaskets
  • HVAC Components
  • Industrial Hose
  • Hydraulic Hose
  • Vacuum Hose
  • Hose Mandrels
  • Washers
