PVCThree-proof tarpaulin‘s plastic-coated high-strength polyester waterproof cloth is based on high-strength polyester canvas, coated with polyvinyl chloride (PVC) paste resin and added with A variety of chemical additives such as accelerator, antifungal agent, anti-aging agent, etc. are made by high-temperature plasticization. It is waterproof, mildew-proof, and has a special surface treatment for anti-slip effect. It is an internationally popular waterproof cloth, and its width is extremely large, reaching 2 meters wide. When processing the finished product, it can reduce seams and improve quality. It can be spliced with heat sealing to eliminate the need for seams. Worry about needle hole leakage. And we can produce products with different functions, colors and thicknesses according to user needs.

Because tarpaulin has good anti-aging properties With anti-tear properties, tarpaulins are widely used in transportation, logistics, construction sites, agricultural granaries and other fields. Tarpaulins are widely used and bring great convenience to people’s production and life. Tarpaulins are divided into three levels according to their use requirements: ordinary tarpaulins, three-proof tarpaulins, and five-proof tarpaulins. Among them, what exactly are “three-proof tarpaulin” and “five-proof tarpaulin”? Below I will tell you more about tarpaulins in detail. “Three defenses” have different interpretations in different fields. Baidu Encyclopedia’s explanation of “three defenses” refers to “anti-nuclear weapons, anti-biological weapons, and anti-chemical weapons.” In the electronics industry, “three defenses” refers to “anti-nuclear weapons, anti-biological weapons, and anti-chemical weapons”. Anti-fungal, anti-moisture, anti-salt spray”; in the agricultural field, the three anti-droughts refer to “anti-drought, anti-waterlogging, and anti-wind”; in industry, the three anti-freezes refer to “anti-freeze, anti-skid and anti-poisoning”; in the construction industry, they refer to “Waterproof, fireproof and shockproof”
Three-proof tarpaulinFollow the above. There are differences in the “three-proof” mentioned. The three-proof tarpaulin mainly refers to anti-aging, waterproofing, and anti-mildew; in addition to the three-proof, the five-proof tarpaulin must also be fireproof and anti-corrosion. It requires a water pressure resistance value of ≥2000MM water column. The cold resistance temperature is -20℃, the mildew resistance test is level one, and the flame retardant grade is V-2 or above. These are the main requirements for three-proof tarpaulin and non-proof tarpaulin.
Due to the extremely high quality requirements for three-proof tarpaulins and five-proof tarpaulins, they are mainly made of PVC material. Users also The grade of tarpaulin can be selected according to needs. The following are the main application fields of PVC three-proof tarpaulin:

1. Freight tarpaulin for cars and trains;

2. Used to cover open-air warehouse stacks;

3. Build temporary granaries and various cropsFor covering the sky;

4. Construction sites, electric power construction sites, etc. Build temporary work sheds at construction sites;

5. Outer sheaths for various machines and equipment ;
