Introduction: Choosing the Right Synthetic Rubber
In demanding industries such as automotive, marine, and chemical processing, the type of rubber used determines safety, longevity, and efficiency. While EPDM and NBR are widely used, CSM (Chlorosulfonated Polyethylene, known as Hypalon®) consistently outperforms both in key areas. At YQXPOLYMER, we provide high-quality CSM products that meet rigorous industrial standards.
🔍 Key Parameter Comparison
| Property | CSM / Hypalon® | EPDM | NBR |
| Chemical Resistance | Excellent – resists acids, bases, ozone, oxidizers | Poor – not suited for oils or acids | Excellent oil & fuel resistance, poor chemical range |
| Weather & UV Resistance | Outstanding – long-term outdoor durability | Good – prone to shrinking over time | Limited – degrades with ozone or UV exposure |
| Temperature Range (°C) | -40 to +120 | -50 to +130 | -30 to +100 |
| Tensile Strength | High | Moderate | Good |
| Flexibility at Low Temp | Excellent | Excellent | Moderate |
| Aging / Ozone Resistance | Excellent | Very good | Poor |
| Oil Resistance | Good | Poor | Excellent |
| Flame Resistance | Good (self-extinguishing) | Poor | Moderate |
| Applications | Cable jackets, hoses, gaskets, covers, marine uses | Seals, automotive weather strips, roofing membranes | Fuel hoses, gaskets, oil-resistant gloves |
✅ Why CSM / Hypalon® Wins
- Balanced resistance: Unlike EPDM and NBR, CSM offers a well-rounded resistance to both chemical and environmental factors.
- Durability: With excellent UV, ozone, and heat resistance, it’s ideal for outdoor and high-risk environments.
- Mechanical reliability: Maintains flexibility and tensile strength across a wide temperature range.
🧰 Ideal Applications for CSM Rubber
- Industrial hoses and tubing
- Chemical-resistant linings and tank seals
- Marine and inflatable structures
- Cable jacketing and insulation
- Automotive weather-resistant parts
