Advantages of Cosmetic Aluminum Tube
The advantages of Cosmetic Aluminum Tube can be summarized in three main areas:
I. Outstanding hygienic performance:
Cosmetic Aluminum Tube is a special polyethylene material with clean and non-toxic inner and outer layers.Most importantly, the middle layer of the Cosmetic Aluminum Tube is aluminum, which blocks not only light but also oxygen.It is well known that the environment of microorganisms must be phosphatic and aerobic.The middle aluminium layer of the Cosmetic Aluminum Tube eliminates the growth of microorganisms and algae beyond the reach of a fully plastic tube.
II. Excellent high and low temperature resistance:
Cosmetic Aluminum Tube has a maximum temperature of 110 degrees and a small coefficient of thermal expansion.It corresponds to the thermal expansion coefficient of aluminium and is only one-sixth of the total plastic tube.When the temperature changes, the deformation is small and Cosmetic Aluminum Tube is flexible coil. The pipe itself can digest a certain amount of deformation without causing thermal expansion deformation of the pipe system.However, the high and low temperature resistance of all-plastic pipe is relatively poor.
3. Long service life: PE plastics used by Cosmetic Aluminum Tube, molecular chain structure (-CH2-CH2-) is relatively stable in plastics, and since the inner and outer layers of Cosmetic Aluminum Tube are isolated by the intermediate aluminium layer, outer plastics can be added with stabilizers sufficient to resist light and oxygen aging without affecting the hygiene of inner layers contacting water, thus enhancing its aging resistance.
