PVC S-1300 ,1300 type PVC resin is mainly used in wire and cable,high strength film products ,artificial leather ,soft board/sheet ,plastic shoes and thermoplastic elastomer and other fields due to 1300 type PVC resin than general 1000 type PVC resin molecular quality high viscosity, so its in the processing process and mixing with It is different from the aspect
At present, most cable material manufacturers in order to improve product performance, have used higher degree of polymerization 1300 type PVC resin instead of the original use of 1000 type PVC resin, and even some manufacturers have begun to use higher degree of polymerization 1700 or even 2500 type PVC resin to produce higher performance of high-grade cable material.
PVC S-1300 is mainly used for the production of soft products.When the plasticizer to reduce the viscosity of PVC melt, processing temperature obviously down PVC melt flow change line and viscosity change and plasticizer varieties and dosings have a direct relationship.
