Cosmetic plastic hose materials from which several aspects of the selection? The choice of cosmetic plastic hose: 1. Cosmetic plastic hose materials of health first, the materials used shall comply with relevant national standard of health, harmful substances such as heavy metals and fluorescent agent should be controlled within the scope of the provisions of the standard. 2. Cosmetic plastic hose material blocking performance if some cosmetic companies need packaging products are some particularly sensitive to oxygen or aroma is very volatile product, should choose five layers co-extrusion tube at this time. On the double tube: using high density polyethylene and low density polyethylene material. High-speed rotation method is used to realize uniform mixing effect, softness and hardness of the hose may be appropriately adjusted. Compared with the single pipe, double pipe body thicker, has better corrosion resistance, lower oxygen permeability, and is used by most of the cosmetic company and cosmetics manufacturers. 3. Cosmetic plastic hose materials stiffness of daily chemical companies have different requirements on stiffness of the hose, so how to obtain the required stiffness? Low density polyethylene, high density polyethylene and linear low density polyethylene is typically used for hose. High density polyethylene stiffness is better than low density polyethylene, so it can through adjusting the proportion of high density polyethylene and low density polyethylene to obtain the required stiffness. 4. Cosmetics chemical resistance high density polyethylene plastic hose materials has better chemical resistance than low density polyethylene. 5. Cosmetic plastic hose material weatherability of short-term or long-term performance in order to control the hoses, should consider the following factors: appearance, compression/drop in performance, environmental stress cracking resistance, sealing strength, taste and the loss of the active ingredients and so on.
