Sheet material

Chlorinated rubber (CR) chemical formula: [C10H11Cl7]n

Chlorinated rubber is a chlorinated polymer produced by the reaction of natural rubber with chlorine. The industrial product is a white or pale yellow powder, non‑toxic and odorless, with a chlorine content of 63–65% and an average molecular weight of 5,000–10,000. It is readily soluble in aromatic hydrocarbons, halogenated hydrocarbons, and ethers.

Chlorinated EVA (CEVA)

Chlorinated EVA appears as yellow or pale‑yellow granules, exhibiting excellent softness and elasticity, along with good adhesion to other materials. It is soluble in solvents such as toluene and xylene, possesses rubber‑like elasticity, and demonstrates favorable solubility and flowability at room temperature. Furthermore, it offers outstanding weather resistance, resistance to thermal aging, chemical resistance, oil resistance, ozone resistance, and flame retardancy.

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 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.
