PET plastic products are actually very common in life. For example, the cosmetic bottles and cosmetic bottles that we often drink are basically injection molded with cosmetic-grade pet raw materials. Safety is beautiful. , So what special features will pet materials have to boldly use in cosmetics?
PET has the following advantages
. It has good mechanical properties, the impact strength is ~ times that of other films, and the folding resistance is good.
. Resistance to oil, fat, olefinic acid, dilute alkali, and most solvents.
. The heat resistance of pure PET is not high, and the heat distortion temperature is only about ℃, but it is greatly improved after strengthening treatment. The mechanical properties of PET reinforced by glass fiber are similar to engineering plastics such as PC and PA, and the heat distortion temperature can reach ℃; PET has good heat aging resistance, embrittlement temperature is ℃, and still has certain toughness at ℃; PET is not easy to burn , The flame was yellow, and the burning oil dripped.
. The permeability of gas and water vapor is low, and it has excellent gas, water, oil and peculiar smell performance.
. High transparency, can block ultraviolet rays, and good gloss.
. Non-toxic, tasteless, good hygiene and safety, can be directly used in cosmetic packaging.
PET is a milky white or light yellow highly crystalline polymer with a smooth and shiny surface. Creep resistance, fatigue resistance, good abrasion resistance and dimensional stability, low abrasion and high hardness, have the greatest toughness among thermoplastics, good electrical insulation, low temperature influence, but poor corona resistance. It is non-toxic, weather resistant, chemical resistant, low water absorption, resistant to weak acids and organic solvents, but not immersed in hot water and alkali. PET resin has high glass transition temperature, slow crystallization speed, long molding cycle, long molding cycle, large molding shrinkage, poor dimensional stability, crystallization molding is brittle, and low heat resistance. Through the improvement of nucleating agent, crystallization agent and glass fiber reinforcement, PET has the following characteristics in addition to the properties of PBT. .The heat distortion temperature and the long-term use temperature are the highest among the thermoplastic general engineering plastics. Because of the high heat resistance, the reinforced PET is immersed in S in a ℃ solder bath, and it hardly deforms or discolors. It is especially suitable for the preparation of soldered electronic and electrical parts .Bending strength MPa, elastic modulus up to MPa, creep resistance and fatigue resistance are also very good, surface hardness is high, mechanical properties are similar to thermosetting plastics. Since the ethylene glycol used in the production of PET is almost half the price of the butylene glycol used in the production of PBT, PET resin and reinforced PET are the cheapest among engineering plastics and have a high cost performance.
Focus on the customized production of cosmetic-grade plastic bottle packaging, and have a one-stop automatic production line from raw materials and finished products to ensure the safety, stability and controllability of cosmetics. It is a long-term partner of several well-known domestic cosmetics companies such as Chubang Cosmetics, Jiahao Cosmetics, Shenghetang Cosmetics, and Tianhe Cosmetics. Welcome to customize all kinds of pet plastic bottles, and find cosmetic packaging materials for packaging, professional and more reliable!
