Many friends in life have a familiar and vague understanding of plastics. Today, I will take you to understand the names and uses of several basic materials to help you distinguish and classify in daily life.
ABS: ABS is a thermoplastic synthetic polymer resin. It has good balance properties and can be tailored to suit special needs. The physical properties are hard and firm. It can also maintain good compressive strength at low temperatures, high hardness, high mechanical strength, good abrasion resistance, light specific gravity, and a relative heat index of up to 80c. It can also maintain good dimensional stability at high temperatures, fire prevention, simple process, good gloss, It is easy to color and has a lower cost than other thermoplastics. It is widely used in household products and white products.
PP: This material began to develop in the 1930s. At that time, it was mainly used for the top rotating device of safety glass. The perfect combination of transparency and lightness made it an interesting new type of plastic. By the 1960s, this material was discovered by avant-garde furniture designers and used in modern furniture and other indoor environments. The material has a hard surface and is easily recognized as glass when viewed from a long distance. The cast PP flakes can be used as high-quality glass and are suitable for mass production. A variety of manufacturing and processing methods, easy to process a variety of transparent, translucent and opaque, color, surface effects to choose from, excellent resistance to chemical substances and weathering, excellent resistance to chemical substances and weathering, high printing adhesion It can be fully recyclable, excellent visual clarity, special color creativity and color matching, high surface hardness and good durability. Typical uses: display products, retail signs, interior products, furniture, lighting equipment, glass assembly.
CA: CA products have a warm touch, anti-perspiration, and self-luminous. It is a traditional polymer with bright colors and syrup-like transparency. It has been developed since the beginning of the 20th century, even earlier than insulating Bakelite. Because of its marble-like effect, people can often apply it to tool handles, spectacle frames, hair clips and other products, so it is also one of the most easily recognized polymers. Using it as a material for hand-made utensils can combine its excellent pressure resistance with a good feel. The self-luminous component in the material comes from its softness, and slight scratches on the surface can be worn away. It contains cotton and wood (cellulose) components and can be molded by injection, transfer and extrusion. It has low thermal conductivity, flexible production, a variety of visual effects, excellent fluidity, good surface gloss, good electrical insulation, anti-static, self-brightness, high transparency, strong pressure resistance, unique surface vision, and recyclable s material. Typical uses include: tool handles, hair clips, toys, goggles and helmets, glasses frames, toothbrushes, tableware handles, combs, photo negatives.
PET: PET is usually used in the packaging of food and soft drinks. However, because beer is thermally sensitive to oxygen and carbon dioxide, PET is not suitable for beer. There are a total of 5 layers of plastic bottles, and the two layers sandwiched between the main layer of PET are oxygen decay, which can prevent oxygen from entering and exiting. Miller Beer Company, which produced the first plastic beer bottle in 2000, claimed that plastic bottles can keep beer cooler than aluminum cans, and even have the same effect as glass bottles. They can be resealed and are not easily broken. Recyclable (PET is one of the most recyclable plastic resins), excellent chemical resistance, hard and durable, excellent surface polishing, and good pressure resistance. Typical uses: food packaging, electronic products, soft drink bottles, Miller beer bottles.
There are many kinds of plastic materials, and a good basic understanding can better choose the right household items in daily life, which is convenient for the people’s life.
