Rubber grade chlorinated polyethylene

Due to the high heat-, oil-, chemical-, and wearing-resistance, low permanent set, excellent durability and processing property, and other economic factors, Keliren® rubber is widely used in extruded,molded and sheet-shaped product.The main applications are shown below:

Application fields

  • Due to the excellent flame resistance, heat resistance and weather resistance, Keliren® rubber is widely used in the cable sheath for the household appliances, mine, marine, and wind-power.

  • Due to excellent heat-, oil-, flex-, and flame-resistance, the performance of the liquid conveyor hose and oil-gas conveyor hose made of Keliren® rubber is superior to that of hose made of other synthetic rubber, and Keliren® rubber is especially suitable for pressure-bearing liquid conveyor hose.

  • Keliren® rubber also has excellent heat resistance, ozone resistance, air resistance, low-temperature resistance, flame resistance, and flex resistance, and is used in manufacturing flame retardant conveyor belt, heat resistant conveyor belt, and common conveyor belt. Use of Keliren® rubber will greatly extend the service life of the conveyor belt.

  • As the modifier and phase solvent ,Keliren® resin may also be used in flame retardent ABS, SAN, HDPE and PP to improve their impact resistance and flame resistance.

  • Keliren® rubber has high filling capacity for the ferrite magnetic powder, and the magnetic products made of Keliren® rubber is precise and soft, has good low-temperature performance and is widely used in fields of computer, auto, household electrical appliances and motor.

  • Due to the above-mentioned merits, Keliren® rubber is used to produce various rubber pieces , such as car, ship and locomotive.
