PVC Tarp Production Process

The production of PVC tarpaulin involves several key steps:

1. Mixing and Melting

  • PVC resin is mixed with additives (plasticizers, stabilizers, pigments).
  • The mixture is melted at high temperatures to form a molten PVC compound.

2. Extrusion

  • The molten PVC is extruded through a die, forming a flat, continuous sheet.
  • Rollers cool, smooth, and flatten the sheet.

3. Coating

  • The cooled PVC sheet is coated with liquid PVC through the “knife and roller coating” process.
  • A rotating blade applies a layer of liquid PVC to the sheet’s surface.

4. Calendering

  • The coated sheet passes through calender rollers that apply pressure and heat, ensuring a smooth, flat surface.

5. Cutting

  • The PVC tarp is cut to the desired size and shape using precision cutting machines.

6. Quality Testing

  • The tarp is tested for tensile strength and water resistance to ensure it meets quality standards.
