What is PVC rigid sheet?
The full name of PVC rigid board is Polyvinyl Chloride Rigid Sheet. Using amorphous materials as raw materials, it has ultra-high anti-oxidation, anti-acid and anti-reduction properties. PVC rigid boards also have high strength and excellent stability, are non-flammable and resist corrosion caused by climate change. Common PVC rigid boards include transparent PVC board, white PVC board, black PVC board, gray PVC board, gray PVC board, etc.
What are the advantages of PVC sheet?
PVC sheet not only has many advantages such as corrosion resistance, flame retardant, insulation, and oxidation resistance but also because of its good processability and low production cost, PVC sheet has maintained a high sales volume in the plastic sheet market. With its wide range of uses and affordable prices, PVC rigid boards have been firmly occupying a piece of the plastic sheet market. At present, the research and development technology of PVC sheet in China has reached the international advanced level.
What are the categories of PVC rigid sheet/film?
There are many kinds of PVC sheets, there are different types of PVC sheets, such as thick PVC sheets, thin PVC sheets, transparent PVC sheets, black PVC sheets, white PVC sheets, glossy PVC sheets, matt PVC sheets.
What are the disadvantages of PVC sheet?
The plasticizers in daily PVC sheets mainly use dibutyl terephthalate and dioctyl phthalate. These chemicals are toxic, as is lead stearate (an antioxidant for PVC). Lead precipitates out when PVC sheets containing lead salt antioxidants come into contact with ethanol, ether, and other solvents. Lead-containing PVC sheets are used for food packaging. When encountering fried dough sticks, fried cakes, fried fish, cooked meat products, cakes, and snacks, lead molecules will diffuse into the oil, so PVC sheet plastic bags cannot be used to contain food. Especially oily foods. In addition, polyvinyl chloride plastic products will slowly decompose hydrogen chloride gas at a higher temperature, such as about 50 °C, which is harmful to the human body. Therefore, PVC products are not suitable for food packaging.
What is the application of calendered PVC rigid sheet?
The use of calendered PVC rigid sheet is also extremely wide, mainly used for making PVC Christmas tree film, PVC green film making fence, PVC binding cover, PVC business card, PVC folding box, PVC ceiling piece, PVC playing card material, PVC blister hard sheet, etc.
What is the most common thickness of calendered PVC sheet?
It depends on your requirement, we can make from 0.05mm to 1.2mm.
What is the difference between calendering and extrusion processes?
Although the calendering process can produce better products than the extrusion process, it is not effective and the loss is too large when the specification is too high or the specification is too low.
