Part 1 : Describe them.
PE Tarpaulin No. 1
The procedure used to make PE tarpaulins is drawing circular, weaving, double side sheet with a loosely woven polyethylene plastic strip in the center.
High-density polyethylene (HDPE), low-density polyethylene (LDPE), and linear low-density polyethylene are three different types of the semi-crystalline thermoplastic substance known as polyethylene (PE) (LLDPE).
Among them, HDPE is the starting material used to create PE tarpaulin. It comes in the form of a white powder or granular product, is odourless and tasteless, and has a density between 930 and 970 kg/m3.
Advantages
High electrical insulation, strong heat and cold resistance, good chemical stability, insoluble in any organic solvent at room temperature, resistance to the majority of acids and bases, little water absorption, and good heat and cold resistance are all characteristics of PE tarpaulin. Furthermore, PE tarpaulin is lightweight, hygienic, non-polluting, and simple to store and transport.
Disadvantages
The fact that pe tarpaulin is simple to wear is a drawback. Its performance will suffer due to thermal oxidation, which also makes it brittle and susceptible to age. Because PE tarpaulin's surface toughness is so poor, it is easily scratched and stressed. Moreover, it is unsuitable for prolonged outdoor usage.
Applications
Reinforced polyethylene sheeting, a temporary cover for construction materials, covering temporary fences to protect them from the elements and prolong their service life, as well as tents, cargo coverings, garden bags, and other items are just a few of the numerous uses for PE tarpaulin.
Two PVC tarps
The PVC tarpaulin is formed of high-strength polyester canvas and covered with polyvinyl chloride (PVC) paste resin containing growth inhibitors, anti-mildew inhibitors, anti-aging inhibitors, anti-static inhibitors, and other chemical additives using the impregnation technique.
And the starting point Compared to polyethylene, polyvinyl chloride is somewhat more clear, glossy, and translucent.
Advantages
A durable, economical material with high chemical resistance and mechanical strength is polyvinyl chloride. PVC is also naturally flame resistant and offers the benefits of being both electrically insulating and flame resistant (flame retardant rating of 40 or greater).
The great degree of weather protection that the pvc tarpaulin can provide is due to its excellent durability and sturdiness, water resistance, mildew resistance, cold resistance, age resistance, and antistatic properties.
The pvc tarpaulin, a well-liked worldwide tarpaulin, has a vibrant, colourful look and a specific treatment on the surface with anti-slip functionality.
Disadvantages
The polyvinyl chloride tarpaulin's poor transmittance reduces the amount of natural light that enters the structure. Additionally, it is advised to avoid placing sharp things on pvc tarpaulin while using it since doing so can lessen the tarpaulin's ability to repel water.
Applications
There are several uses for PVC tarpaulin. like the following
often used to cover vessels.
to construct a broad range of tents.

Conclusion
In general, PE and PVC tarpaulin both have their own benefits and drawbacks; regardless of which one you choose, you must base your choice on your project's needs, price range, and other factors.
