How we test elastomer compatibility with refrigerants
Our data-driven approach replicates real-world operational demands, ensuring material selection is based on proven performance and long-term reliability. To ensure optimal performance across real-world applications, we conduct comprehensive in-house validation, aligning our advanced evaluation methods with modified ASHRAE standards. This enables us to verify material behavior under varied thermal and chemical stresses across a broad portfolio of refrigerants and lubricants. By capturing both immediate and long-term material shifts, including volume change, hardness shift, mechanical properties and compression set, we ensure that every material will deliver compliance and high performance in diverse and demanding conditions.
R&D testing capabilities
Trelleborg's R&D network is equipped with over 200 test rigs and 250 material testing devices, enabling comprehensive validation across our entire material portfolio. From custom testing adapted to customer hardware to application-specific simulations, we ensure certified quality and reliability and meet the strictest standards.
Our continued investment in R&D means you benefit from robust, innovative polymer solutions validated through world-class testing and deep global technical expertise. With industry-leading testing capabilities that mirror real-world application demands, we ensure each material is carefully evaluated for reliability, performance and compliance.
