There are many ways to manufacture polyethylene, and the most common one is to polymerize ethylene at a high temperature of 200 to 300 °C and a pressure of 1000 to 2000 atmospheres.

The plastic bottle is made of polyester (PET), polyethylene (PE), polypropylene (PP) as raw materials, after adding the corresponding organic solvent, after being heated at high temperature, it is blown, squeezed, or injection molded through a plastic mold.

The current world economy is undergoing changes, and the domestic industrial structure is also in a stage of continuous upgrading.

Plastic bottles are mainly made of polyethylene or polypropylene and other materials with the addition of various organic solvents.

With the improvement of people's living standards, environmental awareness and attention to health, a green revolution in the building materials industry has been launched in the field of water supply and drainage.

Among non-metallic pipes, the most widely used are plastic pipes.

Plastic pipes are generally made of synthetic resin, that is, polyester, as raw materials, adding stabilizers, lubricants, plasticizers, etc.
