PVC Sheet

PVC sheets are classified based on flexibility, transparency and function to meet diverse needs. Flexible types (30%-50% plasticizers) are bendable, suitable for seals, waterproof strips and packaging. Semi-rigid ones (5%-30% plasticizers) balance stiffness and flexibility, used for PVC table cloth and auto interior liners. Transparent variants fit food display and cosmetic boxes; opaque ones for decoration and billboards.

Calendering and extrusion are the mainstream production processes. Calendering produces high-gloss, precise-thickness sheets for high-quality decoration and transparent packaging. Extrusion, with high efficiency and low cost, is ideal for mass-producing general flexible and semi-rigid sheets like construction liners. A key challenge in both processes is high temperature, which threatens PVC resin stability.

Pure PVC resin is thermally sensitive; high temperatures during processing easily cause degradation, leading to discoloration, brittleness or structural defects. This not only affects product quality but also increases production waste and costs, failing to meet application demands.

TopJoy stabilizers provide targeted solutions to these pain points. They ensure stable processing by inhibiting PVC degradation at high temperatures, while enhancing the material’s durability and resistance to environmental factors. For manufacturers of PVC sheets, TopJoy’s reliable stabilizer solutions help deliver consistent, high-quality products across diverse application scenarios, boosting market competitiveness.
