Have you ever wondered what temperatures CSM (Chlorosulfonated Polyethylene) rubber can withstand? Knowing the temperature range of rubber materials is crucial for choosing the right rubber for specific industrial applications, especially in demanding environments.
The typical temperature range of CSM rubber is approximately -35°C (-31°F) to +150°C (302°F). CSM rubber maintains its flexibility and mechanical properties within this range, making it suitable for a variety of harsh conditions and demanding applications.
Let's explore why temperature range matters, how CSM rubber performs within its specified limits, and which applications benefit from its unique temperature stability.
What Is CSM Rubber?
Chlorosulfonated Polyethylene (CSM) is a synthetic elastomer created by chemically modifying polyethylene through chlorosulfonation.
CSM rubber combines excellent resistance to weathering, ozone, heat, chemicals, and abrasion. It is particularly known for maintaining flexibility over a wide temperature range, making it ideal for outdoor and industrial environments.
Key Properties of CSM Rubber ✅
| Property | Benefit |
|---|---|
| Chemical Resistance1 | Excellent resistance to oils, fuels, and solvents |
| Heat Resistance2 | Stable at temperatures up to 150°C (302°F) |
| Weather Resistance | Superior UV and ozone resistance |
| Mechanical Strength3 | Good tensile strength and abrasion resistance |
These properties make CSM rubber versatile and reliable across various industries.
What is the HS Code for CSM Rubber?
The HS (Harmonized System) code is an international classification system for products used in trade.
The standard HS code commonly used for Chlorosulfonated Polyethylene (CSM) rubber4 is 4002.99.90.
It's important to verify this code with local customs agencies as classifications may differ slightly based on specific product forms or country-specific regulations.
Is CSM the Same as Hypalon?
Yes, CSM rubber is commonly known by the trade name "Hypalon5," which was originally a brand owned by DuPont.
Hypalon is the original trademarked name for Chlorosulfonated Polyethylene rubber produced by DuPont. Although DuPont ceased manufacturing Hypalon, the term "Hypalon" remains widely used as a generic reference to CSM rubber in the industry today.
Why Is the Temperature Range Important for Rubber?
Understanding the temperature range of rubber materials6 like CSM is critical because extreme temperatures can significantly affect rubber’s performance.
Temperature directly impacts rubber’s flexibility, strength, and durability. If a rubber material is used outside its recommended temperature range, it may become brittle, lose elasticity, degrade rapidly, or fail entirely. Selecting rubber with the correct temperature range ensures reliability and safety in applications such as automotive, aerospace, and industrial equipment.
Impact of Temperature on Rubber ✅
| Temperature Effect | Impact on Rubber Performance |
|---|---|
| Too High | Rubber softens, weakens, and rapidly degrades |
| Too Low | Rubber stiffens, becomes brittle, and cracks easily |
| Within Optimal Range | Rubber maintains elasticity, flexibility, and strength |
Ensuring rubber stays within its specified temperature range helps maintain the integrity and longevity of the material.
How Does CSM Rubber Perform at Low Temperatures?
CSM rubber is known for its excellent low-temperature flexibility7, making it suitable for applications exposed to cold environments.
CSM rubber typically performs well at temperatures as low as -35°C (-31°F). At these low temperatures, CSM maintains good flexibility, preventing it from becoming brittle or cracking easily. This makes it an excellent choice for outdoor applications, cold-weather seals, and automotive parts exposed to low temperatures.
Low-Temperature Performance of CSM Rubber ✅
| Temperature | CSM Rubber Performance |
|---|---|
| -35°C (-31°F) and above | Retains flexibility, resists cracking and brittleness |
| Below -35°C | Begins to stiffen, reduced flexibility |
CSM's reliable performance in cold conditions ensures durability and consistent sealing capability in outdoor and cold-weather applications.
How Does CSM Rubber Perform at High Temperatures?
CSM rubber offers excellent heat stability, making it suitable for applications that experience elevated temperatures.
CSM rubber remains stable and performs effectively at temperatures up to around +150°C (302°F). At these high temperatures, CSM retains its strength and resistance to aging, heat degradation, and chemical attack, which makes it ideal for automotive, industrial, and chemical-processing applications.
High-Temperature Performance of CSM Rubber ✅
| Temperature | CSM Rubber Performance |
|---|---|
| Up to 150°C (302°F) | Maintains strength and chemical resistance |
| Above 150°C | Begins to degrade, loss of mechanical properties |
Selecting CSM rubber for high-temperature applications ensures reliability and reduces the risk of premature failure due to heat exposure.
Which Applications Benefit from CSM Rubber's Temperature Range?
CSM rubber’s broad temperature range makes it ideal for various industrial, automotive, and outdoor applications.
Applications that commonly benefit from CSM’s temperature stability include automotive fuel hoses, weather-resistant seals, chemical-resistant gaskets, roofing membranes, and outdoor cables. Its ability to perform consistently in harsh conditions makes it a reliable choice in demanding environments.
Key Applications Utilizing CSM's Temperature Stability ✅
| Application | Reason for Choosing CSM Rubber |
|---|---|
| Automotive Fuel Hoses | Stability at high temperatures, chemical resistance |
| Weatherstripping | Flexibility and durability in cold temperatures |
| Chemical Industry Seals | Heat stability, chemical resistance |
| Outdoor Cables | UV, ozone, and temperature resistance |
CSM rubber’s temperature performance ensures reliability and long-term effectiveness in these critical applications.
Conclusion
CSM rubber has an effective temperature range from approximately -35°C (-31°F) to +150°C (302°F), making it highly versatile for many demanding applications. Its excellent low-temperature flexibility and superior heat stability allow it to perform consistently in harsh environments, making it an ideal choice for automotive, industrial, chemical-processing, and outdoor applications. Understanding the temperature capabilities of CSM rubber helps ensure product reliability and durability.
