Development of crosslinked PVC/thermoplastic polyurethane cable compounds for automobiles
The effects of plasticizing agent content,initiator content,auxiliary crosslinking agent content,and thermoplastic polyurethane( TPU) content on the hardness,mechanical properties and thermal elongation of PVC /TPU system were studied in order to formulate cable compounds for automobiles. The wear resistance and aging resistance of PVC /TPU system were investigated. The results showed that: 1 In the presence of auxiliary crosslinking agent TAIC,the initiator DCP can initiate the crosslinking reaction of PVC /TPU system,and the degree of crosslinking increased with the increase in DCP and TPU content.2 The optimal formula of crosslinked PVC /TPU cable compounds is as follows: PVC 100,calcium zinc stabilizer 8,TO TM 50,TAIC 3,DCP 0. 2,TPU 30,antioxidant 0. 8 parts and proper other additives.Q ualified cable compounds for automobiles can be produced according to the formula.
