What is PVC hard sheet (PVC hard sheet)?

Hard film, also known as film, is the sheet used for plastic absorption, of which the thickness is more than 2mm is called plate, and the commonly used ones are: PET (polyethylene terephthalate) hard film, PVC hard film (PVC), PS (polystyrene) hard film, ABS (engineering plastics).

PS hard sheet has low density, poor toughness, and is easy to burn. When it burns, it will produce styrene gas (hazardous gas), so it is generally used to produce various industrial plastic trays. PVC hard sheet has moderate toughness and is not easy to burn. Chlorine gas will be generated during combustion, which will have a certain impact on the environment. PVC is easy to heat, and can be sealed by sealing machine and high-frequency machine. It is the main raw material for producing transparent plastic products.

PVC hard materials and plates:

Stabilizer, lubricant and filler are added into PVC. After mixing, hard pipes, special-shaped pipes and corrugated pipes of various diameters can be extruded by the extruder, which can be used as downcomers, drinking pipes, wire sleeves or stair handrails. The rolled sheets can be overlapped and hot-pressed to make hard plates of various thicknesses.

The plate can be cut into the required shape, and then welded into various chemical corrosion resistant storage tanks, air ducts and containers with PVC electrodes and hot air.
