Materials for isbm bottles manufacturing

There are PP, PC, PET, PETG, PPSU, PEN, PS, Tritan, etc.
PP (Polypropylene)
PP, also known as polypropylene, is a colorless, odorless, non-toxic, translucent, thermoplastic synthetic resin with excellent performance. It is a colorless and translucent thermoplastic lightweight general-purpose plastic with chemical resistance, heat resistance, Electrical insulation, high-strength mechanical properties and good high wear-resistant processing properties.

PC (Polycarbonate)
PC plastic, the scientific name is polycarbonate, is a high molecular polymer containing carbonate groups in the molecular chain. According to the structure of the ester group, it can be divided into aliphatic, aromatic and aliphatic-aromatic types Among them, the low mechanical properties of aliphatic and aliphatic-aromatic polycarbonates limit their application in engineering plastics. Currently, only aromatic polycarbonates have been industrialized. Due to the structural characteristics of polycarbonates, it has become a A general-purpose engineering plastic that grows rapidly among the five major engineering plastics.

Polycarbonate is a tough thermoplastic resin that gets its name from the co3 group inside it. It can be synthesized from bisphenol a and carbon oxychloride (cocl2). The more common method is the melt transesterification method (bisphenol a and carbonic acid) Diphenyl ester is synthesized by transesterification and polycondensation). What is pc material? In what ways can pc material be applied? Where can pc material be used? 1. Building materials industry: polycarbonate sheet has good light transmittance, impact resistance , UV radiation resistance, dimensional stability of its products and good molding and processing performance, making it more obvious than inorganic glass traditionally used in the construction industry. Technical performance advantages. China has more than 20 polycarbonate hollow building materials production lines , the annual demand for polycarbonate is about 70,000 tons, and will reach 140,000 tons by 2005

PET (Polyethylene Terephthalate)
The container made of this material is a common plastic bottle for soda, also commonly known as "Pote bottle".

Common mineral water bottles, carbonated beverage bottles, etc. It is heat-resistant to 70°C and easily deformed, and there are substances that are harmful to the human body melted out. Plastic No. 1 may release the carcinogen DEHP after 10 months of use. Can not be placed in the car in the sun; do not pack alcohol, oil and other substances.

PETG material is briefly a kind of transparent plastic, which is an amorphous copolyester. The commonly used comonomer for PETG is 1,4-cyclohexanedimethanol (CHDM), which is called polyethylene terephthalate. Alcohol ester-1,4-cyclohexanedimethanol ester. It is a polycondensation product of three monomers, terephthalic acid (TPA), ethylene glycol (EG) and 1,4-cyclohexanedimethanol (CHDM) by transesterification, which is 1,4 more than PET. -Cyclohexanedimethanol comonomer has more ethylene glycol comonomer than PCT. Therefore, the performance of PETG is quite different from that of PET and PCT. It has its own uniqueness. At present, there are only two companies in the world, Eastman from the United States and SK from South Korea, with relatively mature technologies.

HDPE (High Density Polyethylene)
Containers for detergents, shampoos, shower gels, edible oils, pesticides, etc. are mostly made of HDPE. The container is mostly opaque and feels like wax.

Common white medicine bottles, cleaning supplies, bath products. Do not use it as a drinking glass, or use it as a storage container for other items. Incomplete cleaning, do not recycle.

LDPE (Low Density Polyethylene)
Plastic bags that can be seen everywhere are mostly made of LDPE.
Common cling film, plastic film, etc. At high temperature, harmful substances are produced. After the poison enters the human body with food, it may cause diseases such as breast cancer and birth defects of newborns. Do not put plastic wrap in the microwave.

PVC (polyvinyl chloride)
It is a polymer of vinyl chloride. Polyvinyl chloride (PVC) is a synthetic material with many advantages and is an ideal material for engineering plastics. Good chemical stability, resistant to acid, alkali and some chemicals. Moisture resistance, aging resistance, flame retardant. The temperature should not exceed 60 ℃ when used, and it will become hard at low temperature.

It is mostly used to make water pipes, raincoats, school bags, building materials, plastic films, plastic boxes and other utensils. Common raincoats, building materials, plastic films, plastic boxes, etc. It has excellent plasticity and low price, so it is widely used and can only be heat-resistant to 81 °C. It is easy to produce bad substances at high temperature, and it is rarely used for food packaging. Difficult to clean and easy to remain, do not recycle. Do not buy if it is packed with drinks.

Polyvinyl chloride is divided into soft plastics and hard plastics. The soft ones are mainly made into films, used as packaging materials, rainproof products, agricultural seedling raising films, etc., and can also be used as insulation layers for cables and wires, and artificial leather products. Hard ones are generally made into pipes and plates, pipes are used as water pipes and pipes for conveying corrosion-resistant fluids, and plates are used as linings and floors for various storage tanks.

Other related: The natural color is yellowish translucent and shiny. The transparency is better than that of polyethylene and polystyrene, but worse than that of polystyrene. Depending on the dosage of additives, it can be divided into soft and hard polyvinyl chloride. Soft products are flexible and flexible, and feel sticky. The hardness of hard products is higher than that of low-density polyethylene. , while lower than polypropylene, whitening occurs at the inflection point. Common products: plates, pipes, soles, toys, doors and windows, wire sheaths, stationery, etc.

PP (Polypropylene)
A thermoplastic resin obtained by the polymerization of propylene. White translucent, waxy when unpigmented; lighter than polyethylene. The transparency is also better than that of polyethylene (PE), and it is harder than PE.

Common products: basins, barrels, furniture, films, woven bags, bottle caps, car bumpers, etc.
(Common soy milk bottles, yogurt bottles, juice drink bottles, microwave lunch boxes. The melting point is as high as 167 ° C, and it is the only plastic box that can be placed in a microwave oven and can be reused after careful cleaning. It should be noted that some microwave lunch boxes, boxes The body is made of No. 5 PP, but the cover is made of No. 1 PE. Since PE cannot withstand high temperature, it cannot be put into the microwave oven together with the box body.)

PS (polystyrene)
Transparent when unpigmented. When the product is dropped or tapped, it has a metal-like crisp sound, good luster and transparency, similar to glass, brittle and easy to break, and the surface of the product can be scratched with fingernails. Modified polystyrene is opaque.

Due to its low water absorption, it is mostly used to manufacture building materials, toys, stationery, rollers, as well as cup boxes or disposable tableware for beverages in fast food restaurants. Common products: stationery, cups, food containers, home appliance shells, electrical accessories, bowls of instant noodle boxes, fast food boxes. Do not put it in the microwave oven, as it will release chemicals due to high temperature. After filling with acid (such as orange juice) and alkaline substances, it will decompose carcinogens. Avoid packing hot food in a snack box. Do not cook instant noodles in bowls in the microwave.

PPSU (polyphenylsulfone)
The essence of ppsu is polyphenylene sulfone resin, a slightly amber linear polymer, amorphous thermoplastic. The density is 1.29g/cm3, and the main features of PPSU material are: high transparency, high hydrolysis stability, high temperature resistance, chemical corrosion resistance, etc. PPSU material is mainly used in: medical equipment, food processing machinery, electronic instruments and textiles. The most important thing is that PPSU is the most suitable material for feeding bottles. It not only has the transparency of glass feeding bottles, but also has the ability to resist falling of plastic feeding bottles. There is no bisphenol A that is harmful to babies, so it can be said that the material of the bottle is quite perfect.

PPSU is a safe new material polyphenylsulfone, without bisphenol A.
The PPSU feeding bottle is made of the safest new material PPSU (polyphenylsulfone), does not contain bisphenol A, and is resistant to high temperature of 180 degrees. The bottle body is brown and yellowish. The feeding bottle is light, resistant to falling and not easy to break, and it is not easy to produce chemical toxins by brewing heating or steam sterilization. It does not contain bisphenol A, and is heat-resistant to 180 degrees.

1. According to the caliber: divided into standard caliber and wide caliber feeding bottles. The standard caliber was born less time, and now the wide-caliber glass feeding bottle is more and more popular with the public. Compared with the standard caliber, the wide-caliber bottle is more convenient to add milk powder and clean.

2. According to the volume: the market is usually 120ml, 150ml, 220ml, 240ml, etc. It is usually recommended that parents buy at least two large and one small, large-capacity milk, and small-capacity drinking water.

3. According to the configuration: divided into straws with handles and straws without handles. 0-6 months old baby is recommended to use a straw without a handle. For more than 6 months, when the baby can grasp it by himself, you can use a PPSU feeding bottle with a handle straw, which is more convenient for the baby to grasp. The automatic straw allows the baby to hold at any angle. All are convenient for breastfeeding.

4.According to function: divided into ordinary PPSU feeding bottle and PPSU anti-spit feeding bottle. The PPSU anti-spit feeding bottle can reduce the baby's inhalation of air when drinking milk, thereby effectively reducing the phenomenon of flatulence, burping and spitting up after the baby drinks milk.

PEN is the abbreviation of polyethylene naphthalate, which is obtained by polycondensation of dimethyl 2,6-naphthalate (NDC) or 2,6-naphthalenedicarboxylic acid (NDA) and ethylene glycol (EG). An emerging premium polyester.

The chemical structure of PEN is similar to that of PET, the difference is that the benzene ring in PET is replaced by a more rigid naphthalene ring in the molecular chain of PEN. The naphthalene ring structure makes PEN have higher physical and mechanical properties, gas barrier properties, chemical stability, heat resistance, ultraviolet resistance, radiation resistance and other properties than PET.

Due to its excellent gas barrier properties and chemical stability, PEN is used to make fire extinguishers

1. From the point of view of heat resistance: the glass transition temperature of PEN reaches 113°C, while that of PET is only 67°C; the melting point and decomposition temperature of PEN are also higher than those of PET;

2. In terms of moisture regain: PEN is 0.64%, PET is 0.75%;

Due to its thermal stability and low moisture regain, PEN is more suitable for industrial yarns than PET (Note: Industrial yarns are relative to civilian yarns, which are mainly used in industrial fields; wire requirements are higher).

TRITAN Copolyester
Tritan is a new type of plastic raw material. Tritan is the latest plastic material developed by Eastman Company in the United States. Its full name is Tritan Copolyester, Chinese name: copolyester, and Tritan copolyester has obtained NSF/ANSI Standard 51 certification for food equipment materials.

In order to facilitate our daily use and take into account our human memory ability, we often abbreviate some responsible things, and often replace them with a few letters. Although it looks simple, it actually has great connotations. Today we will learn about tritan together. what is it. Tritan has many advantages, such as no BPA, good transparency, strong impact strength, chemical resistance, hydrolysis resistance, high temperature resistance, good fluidity, and easy processing. It has a wide range of applications and is used in some household items, small household appliances, baby products, medical care, cosmetics, outdoor and other fields.
