pvc resin for rigid film
pvc resin for rigid film,
PVC resin film grade, PVC resin for film, PVC resin for transparent film,
Rigid PVC FIlms is a versatile packaging material used for various packing applications. The product is easy to use as against other plastic substrates… its characteristics such as clarity, formability at lower temperatures, easy printability make it a product of convenience.
For the production and use of PVC rigid transparent film,the resin is characterized by narrow distribution of resin polymerization degree to ensure its excellent plasticizing performance and good mechanical properties.Resin fish eyes and impurities are less,products”crystal points”less,excellent transmittance.
Polyvinyl chloride (PVC) resin is a high polymer produced by the polymerization of ethylene. Suspension polymerization is used as the common industrial polymerization method. It is usually a solid that can be softened by heating. When heated, it usually has a temperature range of melting or softening, and can be in a plastic flow state under the action of external forces. The factory can add plasticizer or other auxiliaries to meet the production requirements according to the performance requirements of plastic products.
Grade S-1300 is mainly used to produce high-strength flexible products, pressed materials, rigid and flexible extrusion molding and insulating materials, etc. Such as thin film, thin plate, artificial leather, wire, cable sheath and soft all kinds of profiles
