Chemical & Weather Resistant Elastomer Solutions: CSM Rubber for Extreme Environments
YQXPOLYMER – Professional CSM Materials for Chemical, Sealing & Marine Applications

🌟 Introduction
In industries like chemical processing, sealing, and marine engineering, elastomer components face punishing conditions daily:
Constant exposure to acids, alkalis, oils, and solvents
Ozone and UV radiation attacking surface integrity
High humidity and salt spray accelerating degradation
Extreme temperatures stressing material flexibility
Chlorosulfonated Polyethylene (CSM) has proven to be the most reliable solution when traditional elastomers fall short.
At YQXPOLYMER, we develop and supply premium CSM materials engineered for long-term performance in harsh environments.

🧪 Why CSM is the Preferred Choice
CSM rubber offers a unique combination of advantages:
✅ Chemical Resistance
Withstands acids, alkalis, fuels, and aggressive industrial chemicals better than most elastomers.
✅ Outstanding Weatherability
Exceptional ozone and UV resistance prevents cracking and embrittlement during outdoor service.
✅ Thermal Stability
Operating range from –40 °C up to +150 °C ensures stable performance across temperature swings.
✅ Low Gas and Moisture Permeability
Excellent barrier properties reduce swelling and contamination risk.
✅ Flame Retardancy (Optional Grades)
Self-extinguishing formulations available to enhance safety in critical applications.

⚙️ Comprehensive Performance Testing
All YQXPOLYMER CSM compounds undergo rigorous laboratory testing to verify performance:
Test Category Standards & Methods
Chemical Immersion ISO 1817 (oil, acids, alkalis, solvents)
Ozone Resistance ISO 1431 (crack resistance at 50 pphm/100 pphm)
UV Weathering ASTM G154 (accelerated UV exposure)
Thermal Aging ISO 188 (aging at elevated temperatures)
Flame Resistance ISO 340 / UL 94 V-0 (for flame-retardant grades)
Tensile & Elongation ISO 37 (mechanical strength)
These test results demonstrate consistent durability even after prolonged exposure to the most aggressive environments.
