Product Description

Product Description

CSM (Chlorosulfonated Polyethylene)

Chlorosulfonated polyethylene rubber (CSM), commercially recognized under trade names such as Hypalon®, is a specialty elastomer distinguished by its outstanding resistance to ozone, ultraviolet (UV) radiation, and atmospheric aging. It demonstrates excellent chemical stability in the presence of strong oxidizing acids, including chromic, nitric, sulfuric, and phosphoric acids, as well as alkaline substances like chlo rine dioxide and hy drogen peroxide. This broad-spectrum chemical resistance makes CSM particularly suitable for applications in chemical processing environments, especially where contact with corrosive agents is routine.

 

CSM exhibits inherent flame-retardant properties and is classified as a self-extinguishing material, making it ideal for applications with stringent fire safety requirements. It also offers excellent resistance to abrasion, oxygen, and weathering, which further enhances its suitability for harsh operating environments such as those found in mining and heavy industrial operations.

 

Additional characteristics include low gas permeability, moderate resistance to oils and fats, and good compression set resistance. When compared to chloroprene rubber (CR), CSM delivers superior UV and ozone resistance, making it the preferred choice for outdoor and high-exposure applications.

 

Typical end uses for CSM sheeting and molded parts include components for mining equipment, public transportation systems, chemical containment, and protective linings in environments demanding high levels of fire and chemical resistance.

Excellent aging resistance: CSM molecular structure is saturated with excellent ozone resistance, atmospheric aging resistance and heat resistance, which can be exposed to sunlight or high temperature for a long period of time without easy aging and deterioration, thus prolonging the service life of automotive rubber hose.
Good chemical corrosion resistance: it can resist the erosion of various chemical substances contacted in the process of automobile operation, such as fuel, lubricating oil, refrigerant, brake fluid, etc., to keep the performance of the hose stable and prevent the hose from rupture or leakage caused by chemical corrosion.
Better physical and mechanical properties: with high tensile strength, hardness and abrasion resistance, it can withstand the pressure, tension and friction that the automotive rubber hose is subjected to during the working process, which ensures that the hose can work normally under complex working conditions and is not easy to rupture, wear and tear and other problems.
A certain degree of flame retardancy: CSM has a certain degree of flame retardancy, which in the event of fire and other accidents in the car, can slow down the burning speed of the rubber hose, to buy time for the evacuation of people and rescue, and improve the safety of the car.

Application

1. Reinforced Hose Structures (Textile and Wire Braided)

2. Automotive Hose Systems

CSM's excellent resistance to ozone, UV, and chemicals makes it ideal for producing hoses requiring high durability in corrosive or high-pressure environments.

Textile-reinforced hoses are used for transferring chemicals, fuels, and corrosive fluids in industrial settings (typically 10–40 bar operating pressure).

Wire-reinforced hoses are designed for high-pressure chemical transport (>100 bar), especially in acid wash systems and hydraulic circuits.
CSM's chemical resistance ensures long-term reliability when exposed to agents like sulfuric acid, hy drogen fluoride, or sodium hy pochlorite.

With heat resistance up to 130°C and excellent oil and oxidation stability, CSM is commonly used in:

Power steering pressure hoses

Fuel filler and vapor return hoses

Transmission oil cooling lines
Its low gas permeability (<10^-7 cm³/cm·s·bar) enables compliance with stringent emission standards like Euro VI and CARB for evaporative fuel control.

3. Industrial Rollers

4. CSM Latex Applications

CSM is suitable for rubber rollers in environments requiring chemical, heat, or abrasion resistance. Typical hardness: 30–90 Shore A; roller diameters: 20–600 mm.
Used in:

Printing: UV ink resistance

Pulp and Paper: slurry and chemical contact

Metallurgy: acid bath and process rolls

Textile: chemical-resistant guiding and pressing rollers
It maintains low compression set (<30% at 100°C × 22h), ensuring long service life under repeated load.

With high adhesive strength, flexibility, and flame resistance, CSM latex is used in:

Flame-retardant sealants and coatings

Intermediate damping layers in vibration insulation composites

High-performance water-based adhesives
Particle size: D90 < 1μm; excellent pH and solids control for formulation flexibility
