polyphenyl - Names and Identifiers
polyphenyl - Introduction
polyphenyl(polyphenyl) is a kind of polymer, which is formed by benzene rings. It has the following properties:
1. Chemical stability: polyphenyl has good resistance to acid, alkali, solvent and oxygen, and can maintain stability in a wide temperature range.
2. High temperature stability: The polyphenyl has a high melting point and a low coefficient of thermal expansion, which can maintain stability at high temperatures and is suitable for high temperature environments.
3. Electrical insulation: Because the polyphenyl is non-conductive and has good electrical insulation properties, it is suitable for insulating materials for electronic devices and electrical equipment.
polyphenyl uses include:
1. High temperature material: Because the polyphenyl has high temperature stability, it can be used as a high temperature thermoplastic material and a high temperature lubricant.
2. insulation material: because the polyphenyl has good electrical insulation, it can be used for cable insulation, electrical equipment insulation and insulation materials for electronic devices.
3. Flame-retardant materials: polyphenyl can undergo special flame-retardant treatment and are used to make flame-retardant plastics and flame-retardant materials in electronic devices.
The preparation method of polyphenyl is generally realized by polymerization reaction. Common methods include free radical polymerization, cationic polymerization and anionic polymerization.
Regarding the safety information of the polyphenyl, because the polyphenyl is stable at room temperature and insoluble in common solvents, it has good safety under normal use conditions. However, when processing and heat treating polyphenyl, care should be taken to prevent them from being exposed to high temperatures and open flames to avoid the generation of harmful gases and fumes. In addition, polyphenyl needs to be stored and disposed of properly in accordance with relevant codes and guidelines to avoid adverse effects on the environment and humans.
