Which aspects of the choice of cosmetic plastic hose materials?

Selection of cosmetic plastic hose. Hygiene of cosmetic plastic hose materials. First of all, the materials used should meet the relevant national health standards, and harmful substances such as heavy metals and fluorescent agents should be controlled within the scope of the specified standards. .Barrier properties of cosmetic plastic hose materials. If the products of some daily chemical companies that need to be packaged are certain products that are particularly sensitive to oxygen or products with very volatile aroma, then a five-layer co-extruded tube should be selected at this time. Regarding the double-layer pipe, high-density polyethylene and low-density polyethylene materials are used. The high-speed rotation method is used to achieve a uniform mixing effect, and the softness and hardness of the hose can be adjusted appropriately. Compared with single-layer pipes, double-layer pipes have a thicker body, better corrosion resistance and lower oxygen permeability, and are used by most daily chemical companies and cosmetic manufacturers. .Rigidity of cosmetic plastic hose materials Daily chemical companies have different requirements for the rigidity of the hose, so how to obtain the required stiffness? Low-density polyethylene, high-density polyethylene and linear low-density polyethylene are commonly used for hoses. The stiffness of high-density polyethylene is better than that of low-density polyethylene, so the required stiffness can be obtained by adjusting the ratio of high-density polyethylene and low-density polyethylene. .Chemical resistance of cosmetic plastic hose materials. High-density polyethylene has better chemical resistance than low-density polyethylene. . Weather resistance of cosmetic plastic hose materials In order to control the short-term or long-term performance of the hose, the following factors should be considered: appearance, pressure drop resistance, environmental stress crack resistance, sealing strength, taste and loss of active ingredients.
