PE - Polyethylene
PE plastic, or polyethylene, is a widely used polymer known for its simple molecular structure and ease of recycling. Produced from ethylene monomers, it combines high strength with flexibility and reliable load-bearing performance.
Its naturally glossy surface gives it a clean, aesthetic appearance, while its heat resistance can reach up to 230 °C. PE also offers excellent insulating properties, as it does not conduct electricity, and provides strong resistance to water, moisture, and gas penetration.
With these advantages, PE has become one of the most commonly used plastics worldwide, with global consumption reaching around 60 million tons. It is extensively applied in consumer goods, industrial components, and plumbing systems.
