Reasons for the brittleness of PVC cable materials

The brittleness of PVC cable materials is generally related to the formula components of

PVC resin types, plasticizers, lubricants, fillers, etc. If the high PVC model is selected, the

performance of the cable material will be brittle due to the short PVC molecular chain;



















The amount of plasticizer added is small, the cable material is hard, and sometimes it feels

brittle; If the amount of filler added is too large, the performance of the cable material is

reduced and the strength is not good;

Excessive external lubrication often leads to poor plasticization, which makes the cable

material low in strength and brittle.
