Battery Separator Grade PVC Resin for Possible Insulation Applications

An emulsion grade resin has been checked for the purpose of battery grade separator properties along with suspension grade PVC resin for insulation purpose. The study suggests that when battery separator resin CP172SG is added to K6701, the elongation property decreases with an increase in its content, i.e. the material attains rigidity, suggesting that CP172SG is not a good absorbent of plasticizer. It has been confirmed that the particle sizes of these two resins are not the same and a just physical mixing need not be a homogeneous mixture; and this could affect the properties of the compounded material intended to use for HT cable. The samples CP172SG and K6701 both may be used for LT PVC cable sheathing, and CP172SG cannot be used in XLPE (cross-linked polyethylene) LT cables. However, only sample K 6701 can be used for insulation.
