Many people don't know the difference between PE tarpaulin and PVC COATED TARPAULIN. In literal terms, PE and PVC are definitely different. The following essentially explains the difference between these two tarpaulins.
PE: The chemical name is polyethylene, which is a semi-crystalline thermoplastic material, which is used to make PE tarpaulins. So what are the characteristics of PE? We learned that polyethylene is odorless, non-toxic, feels like wax, has excellent low temperature resistance, good water absorption, good electrical insulation properties, and can be used normally at -70 to -100 degrees Celsius , Chemically stable.
The production of PE tarpaulin generally uses HDPE (high-density polyethylene). This material has a high temperature, hardness, mechanical strength and chemical resistance. Polyethylene is suitable for hollow blow molding, injection molding and extrusion of various products (hard), such as various containers, nets, and straps, and can be used as cable coatings, pipes, profiles, sheets, etc.
The raw material of PE tarpaulin generally refers to colored striped cloth, which is coated with PE film on both sides of PE woven cloth, or polypropylene woven cloth. The production process is: wire drawing-circular woven cloth-double-sided coating. The waterproof performance of this kind of tarpaulin is poor, and the waterproof performance is generally not guaranteed after using it once. The disadvantage is that it is easy to wear and the advantage is that it is light in weight, clean and pollution-free. Generally used in temporary storage for rain and dust prevention, not suitable for long-term use in open air.
PVC COATED TARPAULIN is a plastic-coated high-strength polyester tarpaulin based on high-strength polyester canvas, coated with polyvinyl chloride (PVC) paste resin with speed-increasing agent, anti-mold agent, anti-aging agent, antistatic agent, etc. Various chemical additives, plasticized at high temperature. It has the properties of waterproof, mildew, cold resistance, aging resistance, anti-static, etc.; and the breaking strength, tearing elongation, tearing strength of this product are much better than traditional tarpaulin; PVC COATED TARPAULIN has gorgeous and colorful appearance, which is pleasing to the eye. The surface is specially treated for anti-skid effect. It is an internationally popular waterproof canvas with a large width. When processing the finished product, it can reduce the seam and improve the quality. It can be heat-sealed and spliced to avoid the worry of stitching pinhole leakage. It can also produce products with different functions, colors and thicknesses according to user needs.
PVC COATED TARPAULIN is a polyester filament base fabric and double-sided coating with PVC paste resin. Because it is a dipping process, one-time molding, there is PVC slurry in the gap of the cloth, so it has good waterproof performance. Its production process: polyester filament cloth -Dip coating-drying and setting-calendering and cooling-rewinding, now the tarpaulin on the truck, the storage yard and other rainproof products are made by PVC COATED TARPAULIN. PVC material has good rain resistance and good durability. PVC COATED TARPAULIN has better anti-aging properties than PP and PE tarpaulins. Its waterproof effect is the most significant of all waterproof canvases. It is cold-proof and sun-proof, and is mostly used for long-term outdoor covering. Rain shelter, rain shelter, wind shelter canvas roller blinds for breeding, rain shelter in coal yard, truck transportation, cargo ship cover, etc.
