What is the difference between PVC tarpaulin and PE tarpaulin?
Aug 15, 2018

Many people do not know the difference between PE tarpaulin and PVC coated tarpaulin. Literally, PE and PVC are definitely different. The following is a basic explanation of the differences between the two types of tarpaulin.

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, good water absorption, good electrical insulation performance, and can be used normally at -70 to -100 degrees Celsius. , chemical stability is good.

The production of PE tarpaulins is generally HDPE (High Density Polyethylene), which has a high use 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 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. The waterproof performance of the tarpaulin is poor, and the waterproof performance is generally not guaranteed after one use. The disadvantage is that it is easy to wear, and the advantage is that the quality is light, clean and pollution-free. Generally used in temporary stacking, rainproof and dustproof, it is not suitable for long-term use in open air environment.

PVC tarpaulin is a plastic coated high-strength polyester tarpaulin based on high-strength polyester canvas, coated with polyvinyl chloride (PVC) paste resin with speed increasing agent, anti-fungal agent, anti-aging agent, antistatic agent, etc. A variety of chemical additives, plasticized by high temperature. It has the properties of waterproof, mildew proof, cold resistant, aging resistant, antistatic, etc.; and the breaking strength, tear elongation and tearing strength of this product are much better than traditional tarpaulin; the appearance of the product is colorful and pleasing to the eye. The surface is specially treated to prevent the anti-slip effect. It is an internationally popular waterproof canvas, and the width is extremely large. When the finished product is finished, the seam can be reduced to improve the quality. The heat sealing can be used to eliminate the worry of sewing the pinhole. According to the needs of users, we can produce products with different functions, different colors and different thicknesses.

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 the most obvious among 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 transport, cargo ship cover, etc.
