Internal and External Lubrication to Improve Processing Efficiency: In the processing of plastics such as PVC and polyolefins, Fischer-Tropsch wax serves as an excellent external lubricant. It reduces friction between the material and processing equipment (such as screws and molds), thereby lowering torque and energy consumption and increasing production speed. At the same time, it also provides some internal lubrication, improving the flowability of the polymer melt and ensuring smoother processing.
