Related brief description about PU tube hardness and quality is inversely proportional

In the normal trafficking process, customers always encounter numerous doubts the existence of PU tube hardness. Existing Flex PU tube are in accordance with the industry's effort to weigh the Shore scale. I plant commonly used raw material hardness is 85A ~ 95A. A unquestionable reality is, PU material hardness is inversely proportional with the price. In the production and trafficking is among the lasting process, not only to the production staff, to customers and to the formation of a PU material softer prices more expensive, softer quality PU tube more unilateral nature of good insight.
In fact, because of the diversity and complexity, PU using contemporary production have become more common, the use of the production is also increasingly diverse, softness PU Spiral Tube‎ is to be based on the details of production to determine, like tube body necessary embedded object, this time a little low hardness necessary PU tube. The need to clarify that the hardness PU tube Polyurethane air Hose with its own interests and not the quality of indirect contact, but necessary in order to adapt production and life.
Here is necessary particularly point out, the industry PU tube production in winter and summer softness is changed. Winter hardness appropriate point was low because of thermal expansion and contraction of plastic, hard winter tube, PU tube production is low hardness, is more convenient for the customer in the use of, for example, to close the tube key. Summer PU tube hardness will increase a little, higher summer temperatures outside, PU tube expansion, high hardness that is resistant to 10 kg for the low-pressure tube without presenting the case and even bubble burst pipe.
