PVC lubricant adjustment and design

A lot of research and practice show that the degree of plasticizing PVC -u at around 65%, its the best mechanical properties, so when you in the processing of PVC - U must have appropriate knowledge of the plasticizing degree, the lubricant in reducing plasticizing torque at the same time can promote the plasticizing (shorter plasticizing time), extra lubricant in improving the liquidity of PVC -u and also can delay the plasticizing.
