Compared with polyethylene tubing high density (HDPE) ratio of internal surface roughness of other types of tubing is such that the resistance increases almost twice. Thus, the use of corrugated tubing (HDPE) can provide high bandwidth, and consequently, the same water flow in the smaller diameter tubing.
Specially designed corrugated outer surface makes tubing are resistant [...]

Talk of the principal advantages and some disadvantages of plastic pipes in comparison with the metal already stuffed mouth. And we will not be the exception and we emphasize once again the pros and cons of plastic pipes in comparison to our beloved steel (copper pipes for U.S yet to be exotic).
Pluses – low weight [...]

These are the serious limitations of field tests of polymer samples:
• chemical composition of products;
• the angle at which establishes the samples were exposed to the environment;
• time of the year in which testing is conducted;
• geographical location of the test.
The efficiency of microorganisms strongly depends on the chemical composition of the material. Polymers, which [...]
Penopoliuretan – one of the most versatile polymers. Products and designs based on polyurethane used in most industries. In fact, on the basis pepoliuretanov produce elastic (car seats and foam rubber), semi-rigid (various durable goods, such as panel trucks) and hard (insulating sheet) materials.
Of course, one of the key issues is the question of quality [...]
