Thermal Plastic Centralizer Shock Resistance Low Friction Low Density
PP Plastic centralizer with the charactar of low friction, when moving in the downhole with small friction, wear resistance, low torque, low density, rugged, mechanical properites remain stable at -40°C to 220°C. Polyester polymer material is also highly resistant to corrosion and insulation performance, it is suitable for a variety of complex well conditions.
