PVC tarpaulin is a polyester filament base fabric and double-sided coated PVC paste resin. Because it is a dip-molding process, it is formed in one time. There is PVC slurry in the gap of the cloth, so the waterproof performance is good. The production process: polyester filament cloth - Dip coating - drying and shaping - calendering and cooling - winding, now the tarpaulin on the truck, the yard and other rainproof products are made of PVC tarpaulin.

PVC material has good rain resistance and good PVC durability. The anti-aging of PVC tarpaulin is much better than PP and PE tarpaulin. Its waterproof effect is remarkable in all waterproof canvases. It is used for long-term outdoor cover. Rain protection, breeding rain-proof wind-proof canvas roller blinds, coal yard rain, truck transportation, cargo ship cover, etc. PE: Chemical name is polyethylene, which is a semi-crystalline thermoplastic material and is a material for making PE tarpaulins. So what are the characteristics of PE? We understand that polyethylene is odorless, non-toxic, feels like wax, has excellent low temperature resistance, has good water absorption and good electrical insulation properties.  Polyethylene is suitable for hollow blow molding, injection molding and extrusion of various products (hard), such as various containers, nets, packing belts, and can be used as cable coatings, pipes, profiles, sheets, and the like. PE tarpaulin raw material generally refers to color strip cloth, which is coated on both sides of PE woven fabric with PE film and polypropylene woven cloth. The production process is: drawing-round woven fabric-double-sided coating. This kind of tarpaulin has poor waterproof performance. Generally, it can not guarantee waterproof performance after one use. The disadvantage is easy to wear. The advantage is that it is light in weight, clean and pollution-free. Generally used in temporary stacking, rainproof and dustproof, not suitable for long-term use in open air environment. [The difference between PVC coating and PE coating] PVC coating: Features: can be coated thick, relatively cheap, common with calendering process, used for raincoat bags and so on. The PVC feels rough and there is a PVC that is calendered and harder. PE coating: Polyethylene (PE) is non-toxic, low cost and low in consumption.

The feel of PE is softer; the feel of PVC is harder. Common coating classification: 1.PA (polyacrylate) 2. PU (polyurethane) 3. PVC (polyvinyl chloride) 4. PE (polyethylene) In addition, there are polypropylene (PP), polytetrafluoroethylene Ethylene (PTFE), polyamide, polyester, silicone, synthetic rubber, protein.
