With the development of high and new technology, different new materials come out. Today, let's talk about pearl cotton. Maybe many friends do not know what pearl cotton is. Today, the manufacturer of pearl cotton will give a brief introduction and tell how to distinguish the good from the bad.


Pearl cotton is also known as polyethylene foam cotton, is this new type of environmental protection packaging materials, in the rapid development of express company today, people already cannot leave the pearl cotton, relative to those left behind packaging products, pearl cotton not only stable chemical property, and has strong waterproof anti-corrosion shockproof function, not only so, pearl cotton factory produce of pearl cotton also has sound insulation noise reduction, heat insulation, strong toughness, plasticity and so on a lot of advantages and characteristics, is more precious a bit is pearl cotton can be repeated use, pay attention to thrift green environmental protection in today's society, it must be to please the public taste.


As a new type of environmental protection material, pearl cotton is composed of tens of thousands of individual bubbles generated by low-density polyethylene fat after physical foaming. Physical foaming gets rid of all the disadvantages of general polyurethane foaming, such as simple crushing, deformation and poor recovery of foam rubber. It is worth mentioning that the organic chemical characteristics of pearl cotton are unique. Although it also has some characteristics of plastics, the pearl cotton produced by the pearl cotton manufacturer has strong solubility. And can be dissolved fairly neatly, relatively low to air pollution. Because of these physical and chemical characteristics, pearl cotton has become an ideal substitute for traditional packaging products.


So how to distinguish the good from the bad? What kind of pearl cotton is considered to be the high-quality pearl cotton produced by the pearl cotton manufacturer? First of all, is to see, cost-effective pearl cotton m sprint density is very high, but the bubble volume is very small, medical staff in terms of the attitude of the bubble is very well-balanced, and is relatively smooth, can only as pearl cotton, is relatively good ductility, the overall ability to work under pressure, and more symmetrical. In addition, the quality of pearl cotton will bounce up gradually and correct to the original thickness after bearing heavy working pressure, but the inferior pearl cotton will not simply surpass the actual effect.


The relative density of bubble bubbles of inferior quality pearl cotton will be relatively small, and the bubble bubbles will be relatively large. However, after bearing the heavy working pressure, the mole of pearl cotton in the corner of the eye will become thinner, and the correction will be less and less good. And the relative chemical and physical properties of fake pearl cotton will also be reduced. Thermal insulation also has seismic grade characteristics are worse. Now let's make a specific interpretation of the distinction between the quality of pearl cotton and its quality.


First of all, is the flexibility of pearl cotton, quality relatively high quality of the pearl cotton color is soft, because only flexibility relatively strong pearl cotton will be a large number of display information in the application process itself high quality traits, such as in all shipped as soon as possible to protect the product during the whole process, prevent the product does not simply because of the shaking of the whole transport process was damaged.


Insulating the second point, is the pearl cotton stays, as of today often many objects, there are many special products in the transport process of high temperature regulation, because of pearl cotton itself has very good thermal insulation and heat preservation, thus the pearl cotton quality is good or bad, in thermal insulation and heat preservation and to carry out the inspection. This is also very crucial.


Third, is the pearl cotton waterproof and discern the stand or fall of pearl cotton factory produce of pearl cotton can according to the inspection of pearl cotton waterproof, since neither what products, in transport and packaging must be waterproof, thus in view of the pearl cotton waterproof is high, there is a certain products very much, a little water in the process of transporting all can't of, so at the time that the buy good pearl cotton, is waterproof to carry out the detection of him.


The fourth point is the weight of pearl cotton. In the case of the same volume of pearl cotton, the same thickness, length and total width, the lighter the pearl cotton produced by the manufacturer is, the better the relativity of quality is, because the larger the volume of the same gross weight is, the higher the cushioning effect will be.
