Problems solved by technology

[0002] Polyphenylene ether (PPO) has excellent mechanical properties and electrical properties, but its high melt viscosity and poor fluidity make it difficult to process and shape, so it is generally used in various modified varieties, such as PPO and HIPS, PP Polyphenylene ether alloys such as polyphenylene ether or PA have been widely used, and the performance and use value of the blended and modified varieties of polyphenylene ether far exceed their own performance and use value.
[0003] At present, common MPPO materials such as flame retardant and reinforcement cannot meet the application requirements in the field of solar photovoltaics, that is, water resistance, high flame retardancy, long-term thermal oxygen aging resistance, UV stability, and high electrical properties such as CTI and GWIT.

Description

Technical field [0001] The invention relates to a polyphenylene ether composition and its use, belonging to the field of polymer alloys. Background technique [0002] Polyphenylene ether (PPO) has excellent mechanical and electrical properties, but its melt viscosity is high and its fluidity is poor, making it difficult to process and shape. Therefore, various modified varieties are generally used, such as PPO, HIPS, and PP Or PA and other polyphenylene ether alloys have been widely used, and the performance and use value of the blended modified varieties of polyphenylene ether far exceed their own performance and use value. [0003] At present, ordinary flame retardant and reinforced MPPO materials cannot meet the application requirements of the solar photovoltaic field, that is, water resistance, high flame retardancy, long-term thermal and oxygen aging, UV stability, and high electrical properties such as CTI, GWIT and other properties. It is necessary to further improve the pe...
