What Are The Plastic Ingredients Used in Plastic Cosmetic Bottles
General-purpose plastics generally refer to plastics with large output, wide applications, good formability, and low prices. It has five major varieties, namely polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS), and acrylonitrile-butadiene-styrene copolymer (ABS). For example, Plastic Lotion Pump Bottle, Beverage Bottle, and Food Packaging Bottle used in daily life. These five major types of plastics account for the vast majority of plastic raw materials, and the rest can basically be classified into special plastic varieties, such as PPS, PPO, PA, PC, POM, etc., they are used in daily life products very little, mainly It is used in high-end fields such as engineering industry and national defense technology, such as automobiles, aerospace, construction, communications, and other fields.
Plastics are classified according to their plasticity and can be divided into thermoplastics and thermosetting plastics. Under normal circumstances, thermoplastic products can be recycled, while thermoset plastics cannot. According to the optical properties of plastics, they can be divided into transparent, translucent, and opaque materials. For example, PS, PMMA, ABS, PC, etc. are transparent plastics, while most other plastics are opaque plastics. The following are the properties and uses of some commonly used plastics.
- Polyethylene: Commonly used polyethylene can be divided into low-density polyethylene (LDPE), high-density polyethylene (HDPE), and linear low-density polyethylene (LLDPE). Among the three, HDPE has better thermal, electrical, and mechanical properties, while LDPE and LLDPE have better flexibility, impact properties, film-forming properties, etc. LDPE and LLDPE are mainly used in packaging films, agricultural films, plastic modification, etc., while HDPE has a wide range of uses, such as films, pipes, and injection daily necessities.
Special plastics
- Polypropylene: Relatively speaking, polypropylene has more varieties, more complex uses, and a wide range of fields. The varieties mainly include homopolymer polypropylene (homopp), block copolymer polypropylene (copp), and random copolymer polypropylene (rapp) According to different applications, homopolymerization is mainly used in the fields of wire drawing, fiber, injection, BOPP film, etc., copolymer polypropylene is mainly used in household appliances injection parts, modified raw materials, daily injection products, pipes, etc., and random polypropylene is mainly Used for transparent products, high-performance products, high-performance pipes, etc.
- Polyvinyl chloride: Because of its low cost and self-flame retardant properties, it has a wide range of uses in the construction field, especially for sewer pipes, plastic steel doors and windows, plates, and artificial leather.
- Polystyrene: As a transparent raw material, it has a wide range of uses when there is a need for transparency, such as automobile lampshades, daily transparent parts, transparent cups, cans, etc.
- ABS: It is an engineering plastic with a wide range of uses. It has outstanding physical-mechanical and thermal properties. It is widely used in household appliances, panels, masks, assemblies, accessories, etc., especially household appliances, such as washing machines, air conditioners, refrigerators, electric fans, etc., The amount is very large, in addition to the plastic modification aspect, the use is also very wide.
