Environmental Management (ISO 14001): RubberQ’s Path to Greener Production

Problem Statement: Chemical Degradation in High-Temperature Applications

Traditional NBR compounds degrade rapidly when exposed to hot water (90°C+) and glycol-based fluids, leading to premature seal failure in automotive cooling systems. Compression set exceeds 40% after 1,000 hours at 125°C.

Material Science Analysis

• NBR Limitation: Acrylonitrile content (18-50%) provides oil resistance but suffers hydrolysis in aqueous environments. Double bonds in the backbone oxidize above 120°C.
• EPDM Solution: Saturated hydrocarbon backbone (no double bonds) resists oxidation. 60-75% ethylene content ensures stability in glycol/water mixtures up to 150°C.
• FKM Alternative (for aggressive chemicals): Fluorine atoms (66-70% by weight) create inert surface. Peroxide-cured grades withstand 200°C continuous service.
