Product Description Product DescriptionIntroduction to Chlorosulfonated Polyethylene (CSM)1. DefinitionChlorosulfonated Polyethylene (CSM), also known as Hypalon, is a synthetic rubber-like thermosetting elastomer. It is derived from high-density polyethylene (HDPE) through chlorination and chlorosulfonation reactions. The introduction of Cl and sulfonyl chloride (SO2Cl) groups into the polyethylene backbone significantly modifies its properties, endowing CSM with excellent chemical resistance, weather resistance, and mechanical strength. These unique characteristics make CSM a versatile material widely used in various industrial applications.2. Physical and Chemical PropertiesPhysical Properties: CSM typically appears as a white or slightly yellowish powder or granular solid. It has a relatively low density, usually around 1.07 - 1.28 g/cm3. CSM exhibits good elasticity and can be processed into various shapes through methods like extrusion, molding, and calendering. Its hardness can be adjusted during production to meet different application requirements, ranging from 40 to 90 Shore A.Chemical Properties: CSM shows outstanding resistance to a wide range of chemicals. It is highly resistant to acids, alkalis, and solvents. For instance, it can withstand exposure to concentrated HCl and NaOH solutions without significant degradation. CSM also demonstrates excellent weather resistance, maintaining its mechanical properties even after long - term exposure to UV radiation, ozone, and extreme temperatures. Additionally, it has good flame retardancy due to the presence of Cl atoms in its structure.3. Production MethodsSolution Process: In this method, polyethylene is dissolved in an organic solvent such as carbon-tetrachloride. Then, Cl gas and SO2 gas are introduced into the solution under specific reaction conditions, usually at a temperature range of 60 - 100°C and in the presence of a catalyst. The reaction leads to the chlorination and chlorosulfonation of the polyethylene chains. After the reaction, the solvent is removed, and the CSM product is isolated through processes like precipitation and drying.Heterogeneous Process: Here, powdered polyethylene is directly exposed to Cl and SO2 gases in a reactor. The reaction occurs on the surface of the polyethylene particles. This process is simpler and more environmentally friendly as it does not require large amounts of organic solvents. However, it may be more challenging to achieve a uniform distribution of Cl and SO2Cl groups compared to the solution process.4. Storage MethodsTemperature and Humidity: CSM should be stored in a cool, dry place. The recommended storage temperature is between 0 - 30°C. High humidity can cause the absorption of moisture by CSM, which may affect its processing properties. Therefore, storage areas should be well - ventilated to prevent the accumulation of moisture.Avoiding Contamination: CSM should be stored away from chemicals that may react with it, such as strong oxidants, reducing agents, and certain types of solvents. It should also be protected from dust and other particulate matter to ensure its quality and purity during storage.5. Market InformationGlobal Production and Consumption: The global production of CSM has been steadily increasing in recent years, driven by the growing demand from various industries. Asia is the largest producer and consumer region of CSM, accounting for a significant portion of the global market share. China, in particular, has seen a rapid expansion of CSM production capacity.Market Trends: The market for CSM is influenced by factors such as raw material prices, technological advancements, and environmental regulations. As environmental requirements become stricter, the demand for CSM in applications with high environmental performance, such as green building materials, is expected to grow.6. Downstream Industry ChainRaw Material Suppliers: The production of CSM depends on raw materials such as polyethylene, Cl gas, and SO2 gas. Polyethylene suppliers play a crucial role in the CSM industry. Additionally, companies that produce Cl and SO2, often as by - products of other chemical processes, are also important links in the raw material supply chain.CSM Producers: These are the manufacturers that convert raw materials into CSM through the production methods mentioned above. They are responsible for quality control and product innovation.Processors and Fabricators: These companies use CSM to produce various end - products. They may transform CSM into sheets, hoses, seals, and other components through different processing techniques.End - Users: End - users of CSM products span multiple industries, including construction, automotive, electrical, and chemical processing.Detailed PhotosProduct ParametersItemSpecificationResultAppearanceWhite or Light Grey Powder/GranulesWhite GranulesCl Content (%)27-45%35.2%Sulfonyl Chloride Content (-SO2Cl)0.5-2.0%1.1%Mooney Viscosity (ML1+4, 100°C)50-12087Tensile Strength (MPa)≥ 8.09.3Elongation at Break (%)≥ 300365Hardness (Shore A)50-8068Volatile Matter (%)≤ 1.00.5Density (g/cm3)1.10-1.351.22Water SolubilityInsolubleInsolubleOdorOdorless or Slight Rubber SmellOdorlesspH ValueNot ApplicableN/AThermal Decomposition Temp (°C)≥ 220235ApplicationApplication FieldsConstruction Industry: CSM is widely used in the construction industry for roofing membranes, waterproofing materials, and sealants. Its excellent weather resistance and chemical resistance make it suitable for long - term outdoor applications, protecting buildings from water, UV radiation, and chemical corrosion.Automotive Industry: In the automotive sector, CSM is used for manufacturing hoses, belts, and seals. It can withstand the harsh conditions in engines, such as high temperatures, oil, and chemical exposure, ensuring the reliability and durability of automotive components.Electrical Industry: CSM is applied in electrical insulation materials. Its good electrical insulation properties, combined with flame retardancy, make it an ideal choice for insulating wires, cables, and electrical equipment, enhancing safety in electrical systems.Chemical Processing Industry: CSM - based products are used in chemical processing plants for pipes, valves, and gaskets. They can resist the corrosion of various chemicals used in the production processes, reducing maintenance costs and improving the operational efficiency of the plants.CertificationsProduct ListCompany ProfileShandong Jiuchong Chemical Company Limited was founded in 2016, which is located in Weifang City, Shandong Province, China.
