What material is PC? What are the advantages

Summary Description:PC, also known as polycarbonate resin in Chinese, is a colorless, transparent, and non qualitative thermoplastic material with excellent performance in thermoplastic engineering.
PC plastic has outstanding impact resistance, creep resistance, and dimensional stability, as well as heat resistance, low water absorption, toxicity, and excellent dielectric properties. It is one of the five engineering plastics with good transparency and is also a general engineering plastic that has grown rapidly in recent years.
The three major application fields of PC are glass assembly industry, automobile industry and electronic and electrical industry, followed by industrial Machine element, optical disks, packaging, computer and other office equipment, medical and health care, film, leisure and protective equipment, etc.
Characteristics of PC
1. Rigid and resilient, with high impact resistance, high dimensional stability and a wide range of usage temperatures, good electrical insulation, heat resistance, and non-toxic properties. It can achieve the expected results through injection molding and extrusion molding, so the development is very rapid. Currently, the world's annual consumption has exceeded 300000 tons.
2. Polycarbonate is a rigid and tough polymer that is transparent, slightly yellow or white. When burning, it burns slowly, and after leaving the fire, it slowly extinguishes, with a yellow flame and a black smoke carbon beam. After combustion, it melts and bubbles, emitting a foul smell of flowers and fruits.
3. Polycarbonate has excellent performance and excellent light transmittance, with a transmittance of nearly 90%. The relative density is 1.20, which is larger than polyolefin, smaller than Polyoxymethylene and PVC, and similar to polymethyl methacrylate.

Main performance requirements for pigments used in plastic masterbatches

TIme:2023-06--28
1. Coloring power The coloring power of a pigment refers to the amount of pigment required for a certain color product, expressed as a percentage of the coloring power of a standard sample. The coloring power of a pigment is not only related to its properties, but also to its degree of dispersion. The degree of dispersion mainly refers to the degree of refinement of the pigment. The greater the degree of dispersion, the stronger its coloring power, but it has a saturation value. 2. Heat resistance Heat resistance refers to the degree of change in the color or performance of pigments under processing and usage temperatures. When considering the heat resistance of pigments, it is also important to consider their heating time. Due to the different processing methods and heating times of plastics when processed into products, and the different uses and heating times during use, the higher the temperature used, the shorter the heat resistance time. 3. Migration resistance The migration resistance of pigments refers to that the colored plastics may have physical and chemical reactions with the above substances when they are in long-term contact with other solid, liquid, gas and other substances or when they work in a specific environment, which is manifested by the migration of pigments from the inside of plastics to the Free surface of products, or to the adjacent plastics or solvents. 4. Light resistance and weather resistance Plastic products require good light and weather resistance due to long-term outdoor use. Some pigments undergo varying degrees of color changes under light exposure. Weathering resistance refers to the color stability of pigments under natural conditions. Due to its extensive outdoor use, the black mother pays special attention to migration resistance and weather resistance.
