Plastic rods, Dnipropetrovsk region.

Plastic rods are a variety of composite blanks based on polymers that have a round cross-section. Rods can be hollow or solid. Corners and profiles of different cross-sections, which are similar in terms of technical characteristics and purpose, often fall into this category of goods.
The main consumer of such highly specialized goods is light and heavy industry. Spare parts and consumables for any mechanisms or structures are made from plastic rods under production conditions. By mechanical processing of the workpiece, it is easy to make nuts, bushings, washers, gaskets, gears, hardware and other technical details from the rods.
Taking into account that polymers are well susceptible to deformation when changing temperature regimes and processing by cutting, plastic rods are used in agriculture, car service, chemical and food industry, construction and household. When choosing a semi-finished product, the type of material and its technical characteristics are always taken into account. After all, only these criteria determine the reliability and durability of the final product.
Regardless of the field of use, the main criteria for product selection always remain the strength and durability of the manufactured part. Additional requirements include good weldability (at the molecular level by the polymer diffusion method). 4 types of polymer materials are suitable for the above characteristics:

o Polypropylene (PP). Plastic rods guarantee flawless durability of any product or structure. They are perfectly machined and welded. The only drawback is the high price (compared to other types of materials).
o Polyethylene (HDPE). Increased elasticity and lightness, along with ecological safety, make polyethylene the most sought-after material in the food industry.Semi-finished products are presented in a huge assortment and price range, which attracts the attention of buyers even more.
o High molecular weight polyethylene (HMPE). The rather expensive material has a number of technical characteristics that attract manufacturing enterprises and the defense industry. Plastic VMP rods help to produce durable parts and structures resistant to an aggressive environment.
o Ultra high molecular weight polyethylene (UHMWPE). It refers to structural polymer materials of a new generation. Having all the characteristics of VPM, plastic has resistance to shock loads and easily tolerates sharp temperature changes (from -30 to +140 degrees Celsius).
