Many people don't know the difference between PE tarpaulin and PVC plastic tarpaulin. In terms of materials, polyethylene and polyvinyl chloride must be different. The following are the essential differences.
Polyethylene: The chemical name is polyethylene, which is a semi-crystalline thermoplastic material used to make PE tarpaulin materials. So what are the characteristics of sports? We know that polyethylene is odorless, non-toxic, feels waxy, has excellent low temperature resistance, has good water absorption, good electrical insulation properties, can be used at normal -70--100 degrees Celsius, and has good chemical stability.
The production of PE tarpaulin generally uses HDPE (High Density Polyethylene), which has high temperature, hardness, mechanical strength and good chemical resistance. Polyethylene is suitable for hollow blow molding, injection molding and the extrusion (hard) of various products, such as various containers, nets, packaging tapes, and can be used as cable coatings, pipes, profiles, sheets, etc.
PE tarpaulin material generally refers to the color of the cloth. The cloth is also useful in double-coated PE film, PE woven polypropylene woven cloth, and its production process is: drawing circle-weaving-double-sided film. The waterproof performance of this kind of tarpaulin is poor, and the waterproof performance is generally not guaranteed. The disadvantage is that it is easy to wear, and the advantage is that it is light, clean and pollution-free. Generally used for temporary stockpiling to prevent rain and dust, not suitable for long-term use in the open environment.
PVC tarpaulin is a film-coated polyester tarp made of high-strength polyester sails, using polyvinyl chloride (PVC) paste resin with growth agents, antifungal agents, anti-aging agents, antistatic agents and other chemical additives, high-temperature plastics and . It is waterproof, mildew-proof, cold-resistant, aging-resistant, and anti-static; the product's breaking strength, tear elongation, and tear strength are better than traditional tarpaulins; the product has a bright and colorful appearance and excellent product quality. The surface is specially treated with anti-skid function. It is an internationally popular waterproof canvas with a large width. The finished product can reduce the quality of the joints. It can be heat-sealed and the sewing needle hole can leak water. It can also produce products with different functions, colors and thicknesses according to user needs.
PVC paste resin double coating, because a gap is formed in the process of bottoming, so it has good waterproof performance. The production process of polyester cloth: long dip coating, drying, shaping, light pressure cooling and winding, now the tarpaulin on trucks, Rainproof supplies such as the yard are made of PVC tarpaulin. Polyvinyl chloride PVC rains well, works well, aging is significantly better than PP and PE PVC tarpaulin tarpaulin, the waterproof effect is the most significant cold sun, all waterproof canvas, mostly long-term outdoor products including rain, Yuyufeng farm, rolling canvas, car transportation, goods including commodities, etc.pvc tarpaulin fabric
