PVC material for cover brief introductions --

In this article, when we say Vinyl material, we actually mean PVC. We think PVC is a good material for cover after treatment by radiofrequency die cutting machine.

PVC, abbreviated from polyvinyl chloride, is one of the most popular and widely used plastic materials, surely polyethylene and polypropylene are also popular as PVC.
 
PVC is commonly used in construction because it is more effective than traditional materials such as copper, iron or wood in pipe and profile applications. It can be made softer and more flexible by the addition of plasticizers, the most widely used being phthalates. In this form, it is also used in clothing and upholstery, electrical cable insulation, inflatable products and many applications in which it replaces rubber.
 
Pure polyvinyl chloride is a white and brittle solid. It is insoluble in alcohol, but slightly soluble in tetrahydrofuran. About 80% of production involves suspension polymerizationEmulsion polymerization accounts for about 12% and bulk polymerization accounts for 8%. Suspension polymerizations afford particles with average diameters of 0.10 - 0.18mm, whereas emulsion polymerization gives much smaller particles of average size around 0.0002mm.
 
VCM and water are introduced into the reactor and a polymerization initiator, along with other additives. The reaction vessel is pressure tight to contain the VCM. The contents of the reaction vessel are continually mixed to maintain the suspension and ensure a uniform particle size of the PVC resin. The reaction is exothermic, and thus requires cooling. As the volume is reduced during the reaction (PVC is denser than VCM), water is continually added to the mixture to maintain the suspension.
 
Based on different density, PVC can be rigid or flexible. When the density is upper than 1.30gsm per cube cm, it will be rigid. We usually use flexible PVC for bible cover. PVC materials could be calendered with various pattern, and various colors too when PVC layer is produced. After heat die cutting, the PVC can be used as cover for bibles, dictionaries, manuals and so on. Meanwhile, other treatment options are also available such as foil stamping and various silk screening.  
 
PVC mechanical properties enhance with the molecular weight increasing, but decrease with the temperature increasing. The mechanical properties of rigid PVC (uPVC) is very good, the elastic modulus can reach to 1,500-3,000 MPa. The soft PVC (Flexible PVC) elastic is 1.5-15 MPa.
 
The heat stability of PVC is very poor. when the temperature reaches 140 degree Celsius, the PVC starts to decompose. Its melting temperature is 160 degree Celsius. The linear expansion coefficient of the PVC is small and has flame retardancy, the oxidation index is up to 45 or more.
 
PVC is a polymer with good insulation properties but because of its higher polar nature the electrical insulating property is inferior to nonpolar polymers such as polyethylene and polypropylene.
 
As the dielectric constant, dielectric loss tangent value and volume resistivity are high, the corona resistance is not very good, it is generally suitable for medium or low voltage and low frequency insulation materials.
