1. What is Rigid PVC sheet?
The full name of PVC rigid sheet is polyvinyl chloride rigid sheet. Rigid PVC sheet is a polymer material made of vinyl chloride as raw material, with stabilizers, lubricants and fillers added. It has super high antioxidant, strong acid and reduction resistance, high strength, excellent stability and non-flammability, and can resist corrosion caused by climate change. Common PVC rigid sheets include transparent PVC sheets, white PVC sheets, black PVC sheets, colored PVC sheets, gray PVC sheets, etc.
2. What are the advantage of Rigid PVC sheet?
Rigid PVC sheets have many advantages such as corrosion resistance, non-flammability, insulation, and oxidation resistance. In addition, they can be reprocessed and have low production costs. Due to their wide range of uses and affordable prices, they have always occupied a part of the plastic sheet market. At present, our country's improvement and design technology of PVC sheets has reached the international advanced level.
3. What are PVC sheet Used For?
PVC sheets are extremely versatile, and there are different types of PVC sheets, such as transparent PVC sheets, frosted PVC sheets, green PVC sheets, PVC sheet rolls, etc. Due to its good processing performance, low manufacturing cost, corrosion resistance and insulation. PVC sheets are widely used and are mainly used to manufacture: PVC binding covers, PVC cards, PVC hard films, hard PVC sheets, etc.
4. What are the Disadvantage of PVC sheet?
PVC sheet is also a commonly used plastic. It is a resin composed of polyvinyl chloride resin, plasticizer, and antioxidant. It is not toxic in itself. But the main auxiliary materials such as plasticizers and antioxidants are toxic. The plasticizers in daily PVC sheet plastics mainly use dibutyl terephthalate and dioctyl phthalate. These chemicals are toxic. The antioxidant lead stearate used in PVC is also toxic. PVC sheets containing lead salt antioxidants will precipitate lead when they come into contact with solvents such as ethanol and ether. Lead-containing PVC sheets are used for food packaging. When they encounter fried dough sticks, fried cakes, fried fish, cooked meat products, pastries and snacks, etc., lead molecules will diffuse into the oil. Therefore, PVC sheet plastic bags cannot be used to hold food, especially food containing oil. In addition, polyvinyl chloride plastic products will slowly decompose hydrogen chloride gas at higher temperatures, such as around 50°C, which is harmful to the human body.
5.Is PVC Sheet Food Safe?
PVC sheet can be food safe, but only when it is produced using food-grade PVC materials and compliant additives. Food-grade PVC sheets are non-toxic, odorless, and suitable for indirect or direct food contact, depending on the formulation and application.
Food-safe PVC sheets are widely used in food packaging, blister packaging, cling films, food trays, and protective covers. They offer good chemical resistance, transparency, and barrier properties, making them suitable for many food-related applications.
However, not all PVC sheets are food safe. Industrial-grade PVC sheets may contain plasticizers or additives that are not approved for food contact. To ensure safety, always verify that the PVC sheet meets FDA, EU (EC) food contact regulations, and request material safety certifications from the manufacturer.
6.Is PVC Sheet Flame Retardant?
Yes, PVC sheet is naturally flame retardant compared to many other plastic materials. Due to its high chlorine content, PVC is self-extinguishing once the external flame source is removed, which significantly reduces fire spread.
PVC sheets are commonly used in applications where fire safety is important, such as construction materials, wall panels, electrical insulation, signage, and industrial enclosures. In many cases, PVC sheets can meet international flame retardancy standards such as UL94 V-0 / V-1 or equivalent, depending on the formulation.
For projects with strict fire safety requirements, flame-retardant PVC sheets with enhanced performance can be customized to meet specific building codes and fire resistance standards.
