Epichlorohydrin Rubber with Free Lead& Nickel and the Products

The high saturation of the chlorinated polyether rubber molecules endows it with excellent ozone resistance, heat resistance, cold resistance, oil resistance, flame resistance, solvent resistance, gas permeability resistance, etc. Due to its outstanding properties, chlorinated polyether rubber has a wide range of applications. Especially with the rapid development of the automotive industry, it will be increasingly favored.

The traditional vulcanization system of chlorinated polyether rubber is a system that combines thioureas and lead oxide. The anti - aging agents commonly used are also organic substances containing lead and nickel. Since a large amount of heavy metal salts such as lead and nickel are used in chlorinated polyether rubber, they are toxic to the human body and are prone to decomposition to produce carcinogenic substances, which restricts the use of chlorinated polyether rubber in many fields.

Our company uses a lead - free and nickel - free anti - aging system to replace the traditional anti - aging system. After aging, the tensile strength retention rate of the vulcanized rubber can reach 70%, the elongation at break retention rate can reach 35%, and the tensile set rate can reach 14%.

The products produced have excellent performance, good processability, and low cost. The tensile strength can reach over 14MPa, and they have good high - temperature resistance and corrosion resistance. They can be used to replace fluororubber in many occasions.

This technology has been authorized for one invention patent. The technical level of the achievement is leading in China.
