The main raw material of PE (polyethylene) tarpaulin is polyethylene, a thermoplastic polymer. Polyethylene is derived from petroleum and is the most common type of plastic used in various applications due to its versatility, durability, and cost-effectiveness.

PE tarpaulin is typically manufactured using a process called extrusion, where polyethylene resin is melted and then forced through a die to form a continuous sheet or film. The extruded film is then cooled and stretched to achieve the desired thickness and strength.

PE tarpaulin is available in different grades and thicknesses, ranging from lightweight to heavy-duty, depending on the intended use and required durability. It is known for its resistance to water, chemicals, and UV radiation, making it suitable for outdoor applications where protection from the elements is necessary.

PE tarpaulins are commonly used as covers, temporary shelters, and protective sheets in industries such as construction, agriculture, transportation, and camping. They provide protection against rain, dust, debris, and UV rays, helping to safeguard equipment, materials, and goods from damage or degradation.

It's important to note that there are different types of polyethylene, including low-density polyethylene (LDPE), high-density polyethylene (HDPE), and linear low-density polyethylene (LLDPE). These variations may have slightly different properties and characteristics, but all can be used as raw materials for manufacturing PE tarpaulin.
