What material is the cosmetic plastic hose made of? The material of cosmetic plastic hose is generally vinyl chloride monomer, which is polymerized according to the free radical polymerization mechanism under the effect of peroxides, azo compounds and other initiators or under the effects of light and heat. Vinyl chloride homopolymer and vinyl chloride copolymer are collectively referred to as vinyl chloride resin. Its data is amorphous data. In practical applications, additives such as stabilizers, lubricants, auxiliary processing agents, coloring agents, impact agents, etc. are often added to PVC materials. It has non-combustibility, high strength, weather resistance and good geometric stability. PVC has strong resistance to oxidants, reducing agents and strong acids. However, it can be corroded by concentrated oxidizing acids such as concentrated sulfuric acid and concentrated nitric acid, and is not suitable for touching with aromatics or chlorinated alcohols. Selection of plastic hoses for cosmetics: A. The safety and hygiene of the plastic hoses for cosmetics. B. The barrier function of plastic hoses for cosmetics. If the contents of the packaging of daily chemical companies are products that are particularly sensitive to oxygen (such as some whitening Cosmetics) or products with volatile odors (such as essential oils or some corrosive chemicals such as oils, acids, salts, etc.), five-layer co-extruded pipes should be used at this time. Because the oxygen permeability of the five-layer co-extruded pipe (PE│adhesive resin EVOH adhesive resin│PE) is .~. units.
