UPVC pipe to the PE water supply pipe has a stretch, but the PE water pipe stretch of the PE water pipe to what benefits? Then here simply talk about the benefits of stretching.

Polymers have the widest range of mechanical properties in all known materials due to the fact that the polymer is composed of long chain molecules and the molecular motion has significant relaxation properties. Such as high polymer material has a very high elongation, general PE elongation at break 90% to 950%, through a special production process, the elongation of some materials can be above 1000%, while the ordinary high polymer Material of the elongation at break more than 50% to 100%. Generally require a higher tensile properties of materials with heat shrinkable film and stretch film.
