Product Description
CSM is a synthetic rubber - based material formed through a chemical modification process of polyethylene. Polyethylene, a widely used plastic, serves as the base structure. By introducing into the polyethylene polymer backbone, CSM acquires its distinctive characteristics. This modification process endows it with exceptional resistance to chemicals, weathering, and high temperatures, enabling its application in numerous demanding scenarios.The production of CSM involves a chloro - sulfonation process. Polyethylene is treated with a mixture of. This reaction not only introduces sulfur atoms into the polyethylene chains but also creates sites that are crucial for subsequent vulcanization. Vulcanization is a process that cures the material, enhancing its mechanical properties and giving it its final characteristics.
Manufacturers of CSM are increasingly focusing on sustainability initiatives. This includes the development of more environmentally friendly production processes, the use of recycled materials in CSM production (where feasible), and the design of CSM products with extended service lives to reduce the need for frequent replacement.
In conclusion, chlorosulfonated polyethylene (CSM) is a versatile synthetic rubber with a wide range of properties that make it indispensable in various industries. From its unique chemical structure and production process to its diverse applications and the ongoing efforts to address its environmental impact, CSM continues to play a significant role in modern material science and industrial applications.

Application
Anti-corrosion Protection for Equipment: Used as coatings for pipelines, storage tanks, valves, and chemical equipment in industries such as petroleum, chemical engineering, and wastewater treatment to resist corrosion from acids, alkalis, salts, and organic solvents.
Building Waterproofing Applications: Applied in roof waterproof membranes, basement waterproofing projects, and linings for wastewater treatment plants, capable of withstanding long-term exposure to UV radiation, ozone, and extreme temperatures.
Marine Engineering Scenarios: Used as coatings for ship hulls, offshore platforms, and marine pipelines to combat seawater corrosion and marine organism adhesion.Railway and Aerospace: Used for seals in railway vehicles and gaskets in aerospace equipment, capable of withstanding high-speed friction and atmospheric pressure changes.
Cable Insulation Materials: Applied in power cables, control cables, and automotive wiring harnesses, especially suitable for outdoor or high-temperature scenarios (e.g., power plants, mines, industrial sites).
Electrical Seals and Gaskets: Manufactured into seals for electrical cabinets, connectors, and transformers to prevent the intrusion of moisture, dust, and chemical substances.
Flame-Retardant Material Applications: Due to its low-smoke and low-halogen properties (based on formula design), it is suitable for flame-retardant cables in public buildings and transportation fields.
Automotive Seals and Hoses: Used for engine seals, fuel hoses, and air conditioning pipes, resistant to engine oil, coolant, and atmospheric pollutants.
Bus and Truck Components: Applied in shock-absorbing gaskets, air suspension parts, and exhaust system seals, maintaining flexibility in extreme temperatures (-50°C to 120°C).
Packaging & Shipping
Temperature Control
Optimal Temperature Range: The storage temperature should be maintained between -10°C and 35°C to avoid extreme high or low temperatures.
High Temperature (>35°C): May cause material softening, adhesion, or even accelerate aging.
Low Temperature (<-10°C): May harden the material, increase brittleness, and affect processing performance.
Avoid Heat Sources: Keep away from steam pipes, heating equipment, direct sunlight, and other heat sources. The storage area must be well-ventilated to prevent local overheating.
2. Humidity Control
Relative Humidity: The relative humidity of the storage environment should be ≤70% to avoid a humid atmosphere.
High humidity may cause material moisture absorption, affecting vulcanization performance or triggering surface mildew (especially during long-term storage).
It is recommended to equip dehumidification equipment or desiccants and monitor humidity regularly.
