High Temperature Resistant EPDM Seals (-40℃ to +120℃) | LIXU RUBBER
Welcome to LIXU RUBBER – Your Trusted Manufacturer of High Quality High Temperature Resistant EPDM Seals
For over 15 years, Lixu Rubber has been a leading factory specializing in rubber seals and gaskets production. Our high temperature resistant EPDM seals (-40℃ to +120℃) are engineered with premium EPDM compounds and advanced vulcanization technology, designed to stand extreme temperatures, harsh weather, and tough industrial environments. We supply reliable EPDM rubber seals to global clients in automotive, construction, electronics, HVAC, and water treatment industries, with OEM/ODM services tailored to your exact needs. At LIXU RUBBER, we don’t just sell products – We deliver long-lasting sealing solutions you can count on.
Why Choose Lixu's High Temperature Resistant EPDM Seals?
Our high temperature EPDM rubber seals are made from high-purity ethylene-propylene-diene monomer (EPDM) materials, with a temperature resistance range of -40℃ to +120℃ (short-term up to +150℃). We focus on every detail from raw material selection to final inspection, ensuring each EPDM seal meets international standards and your application requirements. Here are the core advantages that make LIXU’s EPDM seals stand out:
1. Exceptional Temperature & Weather Resistance
Our high temperature resistant EPDM seals maintain excellent elasticity and sealing performance in extreme temperature fluctuations – from -40℃ cold winters in northern regions to +120℃ high-temperature working conditions in industrial machinery. The saturated molecular structure of EPDM material gives our seals superior anti-ozone, UV resistance, and anti-aging properties. After 3000 hours of QUV accelerated aging tests, our EPDM rubber seals still keep over 80% tensile strength retention, ensuring 10-15 years of service life in outdoor applications – 2-3 times longer than ordinary rubber seals.
2. Superior Sealing Performance & Durability
We adopt advanced extrusion and compression molding technology to produce high temperature EPDM seals with precise dimensions (tolerance ±0.05mm) and uniform density. These EPDM rubber seals have low compression set (<5% at 150℃ for 24h), strong resilience, and tight sealing, effectively preventing water, dust, and chemical medium leakage. Our EPDM seals also feature good resistance to water, steam, weak acids, and alkalis, making them ideal for water treatment, HVAC, and sanitary equipment applications.
3. Wide Material Customization Options
Besides standard high temperature EPDM seals, we offer customized formulations to meet your specific needs: flame-retardant EPDM seals (UL 94 V-0 certified), food-grade EPDM gaskets (FDA 21 CFR 177.2600 approved), and oil-resistant EPDM compounds. Whether you need soft EPDM seals (30-50 Shore A) for fragile equipment or hard EPDM gaskets (60-85 Shore A) for heavy-duty machinery, our R&D team will develop the perfect solution for you.
4. Strict Quality Control & Certifications
At LIXU RUBBER, quality is our top priority. We have passed ISO 9001 quality management system certification, and all high temperature resistant EPDM seals comply with RoHS, REACH, and WRAS standards. Every batch of EPDM seals undergoes 3-layer inspection: raw material testing (hardness, tensile strength, purity), in-process monitoring (molding temperature, pressure), and final testing (leakage, dimensional accuracy, aging resistance). We provide test reports and certification documents for every order.
