White Solid PVC Sheet has high hardness and mechanical properties. And increase with the increase of molecular weight, but decrease with the increase of temperature. The mechanical properties of rigid PVC are good, and its elastic modulus can reach 1500-3000 MPa, while the elasticity of soft PVC is 1.5-15 MPa. The linear expansion coefficient of White Solid PVC Sheet is small, it is flame retardant, and the oxidation index is as high as 45 or more; PVC is a polymer with better electrical properties, but due to its high property, the electrical properties are not as good as PP and PE. The dielectric constant, dielectric loss tangent and volume resistivity are large, and the corona resistance is not good, so it is generally suitable for medium and low voltage and low frequency materials; White Solid PVC Sheet can resist most inorganic acids, alkalis, salts, most Organic solvents. Suitable for medicine, chemical anti-corrosion materials.
White Solid PVC Sheet has excellent corrosion resistance, edge properties, and has certain mechanical strength; after secondary processing, it can be made into sulfuric acid (hydrochloric acid) tank (barrel box); empty needle rack for medicine, chemical process rack; public Toilet water tank; various special-shaped products and containers such as templates, decorative panels, exhaust pipes, equipment linings, etc. of processed products. It is an ideal material for chemical, building materials, decoration and other industries. The processing technology of pvc hard board is:
Ingredients and Mixing Process. The quality of the White Solid PVC Sheet compound preparation directly affects the extrusion speed, process parameters and product quality of the extruder, so this process should be strictly controlled. When batching, each component of the formula should be accurately measured to prevent the actual formula from changing due to large errors in measurement, thereby increasing the difficulty of quality analysis and quality control. This is often overlooked in the actual production process and should be paid enough attention.
