PRINCIPLE OF LUBRICANT SELECTION

Shandong Polymer Additives Co.,Ltd | Updated: Nov 01, 2018

PRINCIPLE OF LUBRICANT SELECTION

There is no clear division between internal and external lubricant, and the effects may be different under different conditions.

External lubricant: generally has a longer non-polar carbon chain, molecular polarity is small, and poor compatibility with polymers

Internal lubricant: good affinity and compatibility with polymer

SELECTION principles

(1) high lubricity and Durability

Moderate compatibility with the resin, internal and External Lubrication Balance, do not spray frost, not easy to cause scaling

(3) Low surface tension and low viscosity

(4) The mechanical properties, hot deformation temperature, weather resistance, transparency and electrical properties of the polymer are not reduced, and the secondary processability of the plastic is not affected

(5) The lubircant has good heat resistance and chemical stability, and does not decompose, volatilize or react with resin or other auxiliaries in high temperature processing

(6) Do not corrode the product, does not pollute the equipment, has no toxicity
