High-chlorinated polyethylene Chemical formula: [CH2-CHCl-CH2-CH2]n

High-chlorinated polyethylene Chemical formula: [CH2-CHCl-CH2-CH2]n

High-chlorinated polyethylene is a highly chlorinated derivative of polyethylene, also known as HCPE resin. Because its molecular structure contains no double bonds and the chlorine atoms are randomly distributed, it exhibits excellent weather resistance, ozone resistance, thermal‑aging resistance, flame retardancy, chemical resistance, and oil resistance.
Chlorosulfonated polyethylene Chemical structural formula: {CHHm CHCln CHSO2Cl}x

Chlorosulfonated polyethylene Chemical structural formula: {CHHm CHCln CHSO2Cl}x

Chlorosulfonated polyethylene is produced by chlorinating and then chlorosulfonating polyethylene, yielding a highly saturated, chlorine‑containing elastomeric material. Its average molecular weight ranges from 30,000 to 120,000; specifically, CSM2910 has a molecular weight of 30,000, CSM4010 of 40,000, CSM3304 of 120,000, and CSM2305 of 100,000. It appears as white or off‑white flaky or granular solids, with a relative density of 1.07–1.28. Its Mooney viscosity lies between 30 and 90, and its brittle temperature ranges from −56°C to −40°C. It is soluble in aromatic hydrocarbons and chlorinated hydrocarbons, but insoluble in fats and alcohols; in ketones and ethers, it swells rather than dissolves. Owing to its fully saturated molecular structure, it exhibits excellent resistance to chemical media, ozone oxidation, oil degradation, and flame retardancy. Additionally, it demonstrates weatherability, heat resistance, resistance to ionizing radiation, low‑temperature performance, abrasion resistance, electrical insulation, and superior mechanical properties, making it a high‑performance specialty rubber.
Chlorinated polyvinyl chloride Chemical formula: [C4H5Cl3]n

Chlorinated polyvinyl chloride Chemical formula: [C4H5Cl3]n

Chlorinated polyvinyl chloride (CPVC) is a further chlorinated and modified derivative of polyvinyl chloride (PVC), with a chlorine content typically ranging from 65% to 72% by volume. It appears as a white powder. Depending on its degree of polymerization, CPVC can be classified into high‑viscosity, medium‑viscosity, and low‑viscosity grades. The high‑viscosity grade exhibits superior oil resistance, resistance to acid and alkali corrosion, and elasticity, whereas the low‑viscosity grade is more readily soluble in vegetable oils. Compared with PVC, CPVC dissolves more easily in esters, ketones, aromatic hydrocarbons, and other organic solvents. This material is difficult to ignite, and products made from it do not deform when immersed in boiling water. In addition to inheriting many of PVC’s excellent properties, CPVC offers significantly improved corrosion resistance, heat resistance, solubility, flame retardancy, and mechanical strength. Consequently, CPVC is a high‑performance, next‑generation material widely used in construction, chemical processing, metallurgy, shipbuilding, electrical appliances, textiles, and other fields, with exceptionally broad application prospects.
