Beijing Plastic Products Factory discusses how to prevent bubbles in PVC plastic sheet production

Thread Content

PVC is a flame-retardant material with good chemical stability that generates only low tensile cracking forces. Its material properties also include high strength, high stiffness, and high hardness. The operating temperature range is from minus 15 degrees to 60 degrees, and it can be bonded and welded. Bubbles can form during the production of PVC plastic sheets, and these bubbles can affect their performance. How can one prevent their formation? Beijing Plastic Products Factory discusses how to prevent bubbles in PVC plastic sheet production! 　　PVC plastic sheets are amorphous materials with low moisture absorption and poor flowability. To improve flowability and prevent the formation of bubbles, the plastic can be dried in advance. The molding injection system should be thick and short, with a large gate cross-section, and there should be no dead corners. The mold must be cooled, and its surface may be coated with chromium, among other treatments.
