The hindered amine agent of different structures is combined by the polymer hindered amine agent and several light and heat agents with thermal and metal ion chelating properties, and the hindered amine agent of different structures is combined into a composite of BW-6911 new light agent. It not only improves the migration rate, but also exerts the synergistic effect of hindered amines with different structures, and also has the ability to withstand long-term high thermal oxidative degradation, and its performance is better than the general GW-540, GW622, GW-944.

Impurities in graphite can be decomposed into oxides with higher melting and boiling points, such as SiO2, Al2O3, Fe2O3, CaO, and MgO under high temperature conditions. These oxides will react with the metal oxides to form chlorides with lower melting points after being passed through at a certain high temperature and under a certain temperature. Therefore, at a lower temperature, these chlorides can be vaporized and escaped to achieve separation from the graphite, so that the graphite can be purified. The product specifications of tetrahydrofuran-propylene oxide copolymer glycol are shown in Table 3-28. The cost of the copolyether is cheaper than that of pure polytetrahydrofurandiol, and its product performance is similar to PTMG, and it is especially suitable for manufacturing low-temperature resistant polyurethane materials that can withstand cold up to -200°C.
