As the third-widely produced plastic which used in construction in large-scale, polyvinyl chloride has its excellent properties in many aspects and because of which, it gives pvc foam board features as strong, rigid, easy to cut and work with and can be printed on easily. In addition, it is more effective than traditional materials such as copper, iron or wood in many applications.
For its mechanical properties, PVC has very high hardness. The mechanical properties enhance with the molecular weight increasing, but decrease with the temperature increasing. Thus, pvc foam sheet can be made.
PVC is a polymer with good insulation properties but because of its higher polar nature the electrical insulating property is inferior to non-polar 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.
As the heat stability of PVC is very poor and when the temperature reaches 140 °C PVC starts to decompose, so the addition of a heat stabilizer during the process is necessary in order to ensure the product's properties.
Since the cost for PVC's relatively low, and biological and chemical resistance and workability have resulted in it being used for a wide variety of applications. By adding plasticizers, it can become flexible. So Polyvinyl chloride is formed in boards or sheets, that is the PVC celuka board or sheet, in a variety of thicknesses and colors. As flat sheets, PVC is often expanded to create voids in the interior of the material, providing additional thickness without additional weight and minimal extra cost. Sheets are cut using saw and rotary cutting equipment. Plasticized PVC is also used to produce thin, colored, or clear, adhesive-backed films referred to simply as vinyl. These films are typically cut on a computer-controlled plotter or printed in a wide-format printer. These sheets and films are used to produce a wide variety of commercial signage products and markings on vehicles. Also, PVC celuka board is used in a variety of buildings covering the home, hospitals, offices, schools, etc. Complex and 3D designs are possible due to the prints that can be created which are then protected by a clear wear layer. A middle vinyl foam layer also gives a comfortable and safe feel. The smooth, tough surface of the upper wear layer prevents the buildup of dirt which prevents microbes from breeding in areas that need to be kept sterile, such as hospitals and clinics.
