Knowledge

Caustic soda is also called sodium hydroxide, the molecular formula is NaOH, and it is one of the common plastic catalysts.

After the PVC plastic sheet and the preservative are mixed and melted, a three-roll or four-roll calender is used to make a fully transparent or colored film that requires a thin thickness.

Look at the smoothness of its surface, and the one with poor smoothness is recycled plastic;

PVC plastic Film is actually a vinyl aggregate chemical, polyvinyl chloride, which is one of the most produced plastic products in the world.

Amorphous material with low moisture absorption and poor fluidity. To improve flow and prevent the occurrence of air bubbles, plastics can be pre-dried.

The surface of PVC soft board (coil) is glossy and soft. There are brown, green, white, gray and other colors to choose from.

The product is a high-strength, high-transparency plastic sheet produced by high-grade imported raw and auxiliary materials.

General properties PVC resin is a white or light yellow powder with a relative density of 1.35-1.45. The hardness of the product can be adjusted by adding plasticizers.

Rigid PVC extruded sheet is produced by the world's advanced flat CM80 conical twin-screw extrusion production line imported from Milacron, Cincinnati, Austria.

High surface hardness and excellent scratch resistance; surface resistance value is 10 to 6 to 10 8 ohms, with excellent anti-static function, outstanding impact resistance and chemical solvent resist

Using conventional molding methods, PETG sheet can prepare transparent materials with a thickness of 1~25.4mm, with outstanding toughness and high impact strength.

PETG sheets are easy to produce products with complex shapes and large stretch ratios.
