Long-Term Reliability Under Test: Our Automotive Seal Solutions

04/02/2026

Automotive components must endure years of harsh conditions. Demonstrating long-term reliability is crucial for gaining the trust of OEMs and Tier 1 suppliers. This article presents how extensive durability testing validates the robustness of our automotive seal solutions.

An automotive seal, whether for a door, window, or engine bay, is expected to function flawlessly for the vehicle's entire lifespan—often 10-15 years or more than 150,000 miles. This translates to millions of compression cycles, exposure to UV radiation, ozone, road salt, and extreme temperatures ranging from -40°C to over 120°C. Proving that a seal can meet these demands is essential for automotive qualification.

TYM's commitment to reliability goes beyond theoretical design. We subject our automotive seal solutions to rigorous, accelerated life testing. Our in-house test lab conducts standardized tests like ASTM D2000 and customer-specific profiles, simulating decades of use in a matter of weeks or months.
Data from these tests is meticulously analyzed. We track parameters like compression set, tensile strength retention, and surface crack formation. Passing these stringent tests with wide margins provides concrete evidence of our design's robustness. This data is invaluable for our customers during their own vehicle-level validation processes, offering confidence that TYM seals will deliver the long-term performance required in the demanding automotive environment.
