PE: chemical name for polyethylene, it is a semi crystalline thermoplastic material, manufacturing PE tarpaulin material. So what are the characteristics of PE? We know that polyethylene is odorless, non-toxic, feel like wax, has excellent resistance to low temperature performance, has good water absorption, good electrical insulation properties, can be used normally in -70 to -100 degrees Celsius, good chemical stability.
PE tarpaulin production is generally used in HDPE (high density polyethylene), this material has high temperature, hardness, mechanical strength and good chemical resistance. Polyethylene for blow molding, injection molding and extrusion of various products (hard), such as a variety of containers, nets, packaging tape, and can be used as cable coating, pipes, profiles, sheets and so on.
PE tarpaulin material generally refers to the color of the cloth, cloth is in double coated PE film PE woven polypropylene woven cloth is also useful, its production process is: drawing round - weaving - double side film. This tarpaulin waterproof performance is bad, generally used once can not guarantee waterproof performance, the disadvantage is easy to wear, the advantage is that its quality is light, clean and pollution-free. Generally used in temporary cargo, rain, dust-proof, not suitable for long-term use in the open air environment.
PVC tarpaulin is coated polyester waterproof cloth is in high strength polyester canvas cloth, coated with polyvinyl chloride (PVC) paste resin with growth agent, anti mildew agent, anti-aging agent, anti static agent and other chemical additives, the high temperature plastic and. Waterproof, mildew proof, cold resistance, aging resistance, anti-static performance; and the product breaking strength, tearing elongation, tearing strength is much better than traditional tarpaulin; product appearance bright and colorful, it is good to hear or see. The surface of the special treatment of the skid resistant function, is the international popular waterproof canvas, and large width, the processing of finished products can reduce the seam quality, available heat sealing stitching, sewing pinhole free from Water Leakage. And according to user needs to produce different functions, different colors, different thickness products.
PVC fabric is polyester filament fabric and double coating of PVC paste resin, because the dip process, forming a cloth gap which have PVC size, so the waterproof performance is good, the production process of polyester cloth: long - dip - coating drying setting - light pressure cooling and coiling, now on the van the tarpaulin, yard and other rainproof supplies are PVC tarpaulin do. PVC rain is good, PVC work is good, aging is much better than that of PP and PE anti PVC tarpaulin, the waterproof effect is the most significant cold sun, all waterproof canvas, mostly for long time outdoor goods cover rain, rain wind farm yard rain, rolling canvas, truck transport, cargo cover goods etc.
