Many people don't know the difference between PE tarpaulin and PVC tent fabric. Literally speaking, PE and PVC are definitely different. The following essentially explains the differences between these two types of tarpaulins.
PE: The chemical name is polyethylene, which is a semi-crystalline thermoplastic material that is used to make 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, good water absorption, good electrical insulation, 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, and packing tapes, and can be used as cable cladding, pipes, profiles, sheets, etc.
The raw material of PE tarpaulin generally refers to color striped cloth, which is coated with PE film on both sides of PE woven cloth, and polypropylene woven cloth is also used. The production process is wire 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 the temporary storage of goods to protect against rain and dust and is not suitable for long-term use in the open air.
PVC tarpaulin 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, are plasticized at high temperatures.
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 finished products, it can reduce the seam and improve the quality. And can produce products with different functions, different colors, and different thicknesses according to user needs.
