Sound Insulation Transparent PVC Sheet is made of resin through beer extruding, calendering, trimming and other processes. It has light weight, bright and calm surface, good heat resistance, high mechanical strength, excellent chemical stability and electrical insulation. It can be made into daily necessities such as beverage cups and food boxes after thermoforming.
Sound Insulation Transparent PVC Sheet is polypropylene plastic, specific gravity: 0.9-0.91 g/cm3 Molding shrinkage: 1.0-2.5% Molding temperature: 160-220℃. Low density, strength and rigidity, can be used at about 100 degrees. It has good electrical properties and high-frequency insulation and is not affected by humidity, but it becomes brittle at low temperature, and it is not resistant to mold and easy to age. Suitable for making general mechanical parts, corrosion-resistant parts and insulating parts.
1.Sound Insulation Transparent PVC Sheet crystalline material, low hygroscopicity, easy to melt and rupture, and easy to decompose after long-term contact with hot metal.
2. Good fluidity, but the shrinkage range and shrinkage value are large, and shrinkage holes, dents and deformations are prone to occur.
3. The cooling speed of Sound Insulation Transparent PVC Sheet is fast, the pouring system and cooling system should dissipate heat slowly, and pay attention to control the molding temperature. The material temperature is low and the directionality is obvious. It is especially obvious at low temperature and high pressure. When the mold temperature is lower than 50 degrees, the plastic parts are not smooth, and it is easy to produce poor welding, leaving marks, and warping deformation above 90 degrees.
