What Is The Difference Between PVC Tent Fabric And PE Waterproof Tarpaulin?

PE: The chemical name is polyethylene, which is a semi-crystalline thermoplastic material and is the material for making PE tarpaulins. Polyethylene is odorless, non-toxic, feels like wax, has excellent low temperature resistance, good water absorption, good electrical insulation performance, can be used normally at -70 to -100 degrees Celsius, and has good chemical stability.

The production of PE tarpaulin is generally made of HDPE (high density polyethylene), which has a high operating temperature, good 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, packing tapes, and can be used as cable cladding, pipes, profiles, sheets, etc. The raw material of PE tarpaulin generally refers to the color striped cloth, which is coated with PE film on both sides of the PE woven cloth, and also uses polypropylene woven cloth. The production process is: drawing - circular woven cloth - double-sided lamination. This kind of tarpaulin has poor waterproof performance. Generally, the waterproof performance cannot be guaranteed after one use. The disadvantage is that it is easy to wear and tear. It is generally used for temporary storage of goods for rain and dust protection, and is not suitable for long-term use in open air.

PVC tent fabric is a plastic-coated high-strength polyester waterproof cloth, which is based on high-strength polyester canvas, coated with polyvinyl chloride (PVC) paste resin, and added with accelerators, anti-mold agents, anti-aging agents, anti-static agents, etc. A variety of chemical additives, plasticized by high temperature. It has the properties of waterproof, mildew resistance, cold resistance, aging resistance, anti-static and so on; and the breaking strength, tear elongation and tearing strength of this product are much better than those of traditional tarpaulins; the appearance of the product is colorful and pleasing to the eye. The surface is specially treated to prevent slippage. It is an internationally popular waterproof canvas, and the width is extra large. When processing the finished product, it can reduce the seams and improve the quality. And can produce products with different functions, different colors and different thicknesses according to user needs.

PVC tarpaulin is a polyester filament base fabric and then double-coated with PVC paste resin. Because it is a dipping process and one-time molding, there is PVC paste in the gap of the cloth, so it has good waterproof performance. Its production process: polyester filament fabric -Dipping coating-drying-setting-calendering-cooling-winding, now the tarpaulins on trucks, yard and other rainproof items are all made of PVC tarpaulins. The PVC material has good rain resistance, good PVC labor resistance, and the anti-aging effect of pvc tarpaulin is much better than that of PP and PE tarpaulins. Its waterproof effect is the most significant among all waterproof canvases. It can be used for rain protection, aquaculture rain and windscreen canvas roller blinds, coal yard rain protection, truck transportation, cargo ship cover and other purposes.
