PE: The chemical name is polyethylene. It is a semi-crystalline thermoplastic material and is the material for making 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, has good water absorption, good electrical insulation performance, and can be used normally at -70 to -100 degrees Celsius , Chemical stability is good.
PVC tarpaulin is a polyester filament base fabric coated with PVC paste resin on both sides.Because it is a plastic dipping process, it is formed in one time, and there are PVC slurries in the gaps of the cloth, so the waterproof performance is good.The production process: polyester filament cloth -Plastic coating-drying and setting-calender cooling-winding, now the tarpaulin on the truck, yard and other rainproof products are made of PVC tarpaulin. PVC material has good rain resistance, good PVC resistance, and the aging resistance of pvc tarpaulin is much better than PP and PE tarpaulin. Its waterproof effect is the most significant of all waterproof canvases. It is cold and sunproof, and it is mostly used for long-term outdoor cover. Rain-proof, breeding rain-proof wind-proof canvas roller blind, coal yard rain-proof, truck transportation, cargo ship cover cargo and so on.
The production of PE tarpaulin generally adopts HDPE (High Density Polyethylene), this material has a higher 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, packaging tapes, and can be used as cable coatings, pipes, profiles, sheets, etc. The raw material of PE tarpaulin generally refers to the color strip cloth, which is coated with PE film on both sides of the PE woven cloth, and is also used on the polypropylene woven cloth. The production process is: brushed-circular woven cloth-double-sided laminating. This kind of tarpaulin has poor waterproof performance, and it is generally not dare to guarantee the waterproof performance after one use. The disadvantage is that it is easy to be worn, and the advantage is that it is light in weight, clean and pollution-free. It is generally used for temporary stacking, rain and dust protection, and is not suitable for long-term use in open air.
PVC tarpaulin is plastic-coated high-strength polyester waterproof cloth, which is based on high-strength polyester canvas, coated with polyvinyl chloride (PVC) paste resin with speeding agent, mildew inhibitor, anti-aging agent, antistatic agent, etc. A variety of chemical additives, plasticized by high temperature. With waterproof, mildew-proof, cold-resistant, aging-resistant, anti-static and other properties; and the product's breaking strength, tear elongation, tearing strength is much better than the traditional tarpaulin; the product is colorful and colorful, pleasing to the eye. The surface is treated with special anti-skid effect, it is an international popular waterproof canvas, and the width is extra large. It can reduce the seam and improve the quality when processing the finished product. It can be stitched by heat sealing to avoid the worry of sewing needle hole leakage. And according to user needs to produce different functions, different colors, different thickness products.
