Technology and Characteristic：

Chlorosulfonated polyethylene is a high-performance special rubber with a fully saturated main chain and side groups. It can be vulcanized using various systems such as metal oxides, sulfur, polyols, and peroxides, and is suitable for various vulcanization molding methods of elastomers. Due to this structure, CSM possesses numerous characteristics in the rubber industry, including:

1. Excellent Weather Resistance and Ozone Resistance 

   The fully saturated chemical structure of CSM provides exceptional resistance to ozone and ultraviolet radiation, ensuring stable performance even under prolonged exposure to harsh weather conditions. 

2. Outstanding Chemical Corrosion Resistance 

   CSM exhibits excellent resistance to acids, alkalis, salts, and other chemical media, making it particularly suitable for chemical equipment, tank linings, and anti-corrosion coatings. 

3. Good Physical and Mechanical Properties 

   - Tensile Strength: reach over 20 MPa even without reinforcement, making it suitable for high-strength products. 

   - Abrasion Resistance: Comparable to low-temperature styrene butadiene rubber, ideal for wear-resistant applications such as conveyor belts and rubber rollers. 

   - Elasticity and Resilience: Maintains flexibility even at temperatures as low as -40°C.

4. Excellent Flame Retardant Properties

   CSM is self-extinguishing and classified as a flame-retardant material, making it suitable for applications with high fire prevention requirements. 

5. Electrical Insulation and Application Diversity

   CSM has outstanding electrical insulation properties, commonly used for insulation layers and sheaths in wires and cables, particularly excelling in demanding environments such as nuclear power plants. Additionally, it is widely applied in adhesives, damping materials, waterproof membranes, and special rubber fabrics. 

6. Processing Adaptability 

   CSM can be vulcanized using various systems, including metal oxides, sulfur, and peroxides, and is suitable for processes such as extrusion, calendaring, and coating. It can also be blended and modified with materials like PVC and fluororubber to improve overall performance. 

7. Environmental Friendliness and Construction Convenience

   As an anti-corrosion coating, CSM film has strong adhesion, fast drying, convenient construction, and strong adaptability to substrates, and is widely used in fields such as chemical engineering and marine engineering.

Product Applications:

Chlorosulfonated Polyethylene (CSM) is widely used in various industrial fields due to its excellent corrosion resistance, weather resistance, heat resistance, and mechanical properties. Below are its main product application areas and uses:

1. Automotive Industry 

   (1) Seals and Hoses

   CSM is used to manufacture seals and hoses for automotive air conditioning systems, hydraulic systems, and fuel lines. Its chemical corrosion resistance and high-temperature performance ensure reliability in harsh environments. With the development of electric vehicles, the demand for CSM in battery components and cable insulation is further increasing. 

   (2) Interiors and Components

   It is applied in automotive interiors, spark plug caps, steering wheel primers, etc., offering both wear resistance and weather resistance.

2. Wire and Cable Industry 

   (1) Cable Insulation and Sheath

   Due to its excellent electrical insulation properties and UV resistance, CSM is widely used in the insulation layers and sheathing of power cables, submarine cables, and special cables for nuclear power plants. 

   (2) Electromagnetic Shielding Materials

   CSM films are laminated with electrolytic iron foil to produce electromagnetic shielding films, which are used for the protection of electronic devices.

3. Construction Field

   (1) Waterproof and Insulation Materials 

   CSM is commonly used to produce roofing waterproof membranes, ground waterproof layers, and insulation materials. Its weather resistance and waterproofing properties can withstand extreme weather conditions, making it suitable for industrial buildings that require resistance to oil and chemicals. 

   (2) Building Seals and Linings 

   It is used as rubber lining material for industrial pools，tanks, reservoirs, as well as building seal strips, providing long-term corrosion protection.

4. Industrial Products 

   (1) Pipelines and Storage Tanks

   Used in the manufacture of corrosion-resistant pipelines and tank linings, particularly suitable for transporting corrosive media such as acids, alkalis, and salts. 

   (2) Rubber Rollers, Conveyor Belts, and Seals 

   Industrial rubber rollers, conveyor belts, seals, and wear-resistant components made from CSM benefit from its wear resistance, heat aging resistance, oil resistance, ozone resistance, chemical resistance, and mechanical strength, extending the service life of equipment. These are widely used in industries such as steelmaking and printing.

5. Coatings and Corrosion Protection 

   (1) Anti-Corrosion Coatings

   CSM-based coatings are widely used in anti-corrosion projects for chemical equipment, steel structures, ships, and bridges. They exhibit resistance to acids, alkalis, UV radiation, and nuclear radiation. 

   (2) Eco-Friendly Coatings 

   CSM coatings offer excellent shielding properties, with a smooth and flat surface, no color-generating agents, and strong adhesion. They form films at room temperature, dry quickly, and can achieve thick coatings at once, reducing the number of construction times. Additionally, they have low solvent emissions, resulting in minimal environmental pollution.

6. Medical Equipment

   In the medical field, CSM is used to manufacture chemical-resistant medical devices and protective equipment. Although the scale of application is relatively small, it meets specific high-performance requirements. 

7. Footwear Materials

   Chlorosulfonated polyethylene has excellent low-temperature resistance, weather resistance, wear resistance, flame resistance, and durability, along with high tear and tensile strength and superior elasticity. It is widely used in the reinforcement of rubber fabrics for sports shoe soles, snow boots, shoe straps, and other rubber materials.

8.Other Applications:
(1) Colored Rubber Products
To maintain weather resistance, especially to UV rays, products are typically black. However, the use of chlorosulfonated polyethylene allows for the production of brightly colored products without compromising their excellent sun protection, weather resistance, and UV resistance properties.

(2) Hoses
CSM hoses exhibit excellent chemical resistance and low permeability to water and fluorinated refrigerants, making them suitable for various types of air conditioning hoses and other hoses with special requirements.
