Sarlink® TPV and TPE

Sarlink

Thermoplastic Elastomers and Thermoplastic Vulcanizates with
Advanced Performance and Flexibility

Thermoplastic elastomers (TPEs) are a premier choice for soft, flexible materials due to their robust properties, cost effectiveness, and design optionality. Thermoplastic vulcanizates (TPVs) are a subtype of TPEs that combine the flexibility and responsiveness of vulcanized rubber with the durability, longevity, and processability of TPEs. As a global leader in compounding, Teknor Apex offers one of the broadest portfolios of TPV and 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.

Building & Construction

Building & Construction

From residential homes and commercial buildings to industrial projects including highways and railways, Sarlink® TPV thermoplastic materials are a leading choice for construction and building applications. 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 in both indoor and outdoor installations. With cutting-edge performance, Sarlink® TPVs enhance the reliability and durability of construction products. Common applications include:

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

Sarlink® TPVs are engineered for long-term performance in harsh environments, making them perfectly suited for industrial products like seals, gaskets, and hoses. TPVs have displaced thermoset rubber in industrial applications, generally offering better long-term aging performance and increased design flexibility. Sarlink® TPVs in particular have excellent resistance to flex fatigue, chemicals, and extreme temperatures. 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
