Optovaya firma OOO "Energopromteh" (Dnipro, Ukraine) sells polyethylene brand RE-500, rod, white and black. The diameter of the rods is 20-200 mm, the length is 1000 mm. Manufacturers - Germany, Poland and China.
The minimum sales volume is 10-15 kg.
Polyethylene is a thermoplastic polymer of ethylene, the most common plastic in the world. Polyethylene is an organic compound formed by polymerization of ethylene.
It is a thick wax-like mass of white color, but, for example, thin sheets of polyethylene are transparent and have no color. It is resistant to aggressive chemical influences as well as to the effects of frost, is plastic, has excellent cushioning (not sensitive to impact). Heating to 80-120 C leads to softening of polyethylene, but upon cooling it hardens.
Made of polyethylene:
•
Container (jars, boxes, pots for seedlings, etc.)
• Polyethylene film (any packaging film, tape)
• Pipes for drainage systems, sewage and water and gas supply.
• High-voltage and low-voltage wires (good electrical insulation material)
• Armor (body armor and armor panels)
• Geotextile
• Medicine (manufacture of cartilage and joints)
In the field of construction, special types of polyethylene are used to create building materials, such as chlorosulfonated PE, cross-linked PE, ultrahigh molecular weight PE, and foamed PE. The welding of various products made of polyethylene, which is welded by all known methods: contact welding, friction, hot, has become widespread.
gas, filler rod and many others.

Main characteristics of rod polyethylene:
- Good wear resistance (especially supermolecular RE);
- High impact viscosity, even at low temperatures (especially supermolecular RE);
-High deformation characteristics;
-Excellent chemical resistance;
- Low density in comparison with other thermoplastics (g\cm3)
- Low coefficient of sliding friction
- Low adhesion
- Physiological harmlessness;
- High water resistance;
-Very good electrical insulation and dielectric properties.
- Excellent weldability and machinability;
- Moderate mechanical strength, stiffness and yield strength;
-Good resistance to high-energy radiation (gamma and X-rays).
