Cosmetic plastic hose knowledge

Knowledge of cosmetic plastic hose Mechanical properties of cosmetic plastic hose: impact resistance, puncture resistance, flexibility, and tensile strength above 10MPa. Chemical stability of cosmetic plastic hose:

A. Not affected by water at room temperature;

B. Resistant to most dilute acids;

C. Generally not affected by alcohols, aldehydes, ketones and esters;

D. Less affected by halogen at room temperature;

E. At room temperature, it will cause a certain degree of expansion due to the action of aromatic hydrocarbons, aliphatic hydrocarbons and halogen hydrocarbons;

F. Slightly absorb oil, mineral oil and essential oil will escape through polyethylene;

G. Stress cracking may occur under the action of stress cracking agent. Common stress cracking agents include detergents, soaps, oils, fats, and alkali metal hydroxides. Weather resistance of cosmetic plastic hose: Under the action of ultraviolet rays and high-energy radiation, it will degrade in the air, causing discoloration, surface cracking, even embrittlement, loss of strength and loss of use value. Weather-resistant formula should be used, that is, UV absorber should be added , Light shielding agent or light quenching agent, etc.

Barrier properties of cosmetic plastic hoses: Excellent barrier properties to the transmission of water vapor, the higher the density, the stronger the barrier properties. Hygienic performance of cosmetic plastic hose: in line with food hygiene standards. It is non-toxic, tasteless, and can be directly contacted with cosmetics, food and medicine. Forming performance of cosmetic plastic hose: extrudable, easy to heat seal, good thermal stability, good fluidity, and excellent molding performance (any commonly used plastic molding processing method can be used). Cosmetic plastic hose can be made of: colored tube; transparent tube; colored or transparent frosted; pearl tube (pearl, scattered silver pearl, scattered gold pearl); UV, matte (looks elegant, but easy to get dirty), Bright light. Lisson makeup packaging Plastic Products Co., Ltd. is mainly engaged in: plastic cosmetic hose, plastic cosmetic hose.
