Gharda Chemical Co., Ltd. displayed a new type of polyether fluorene with rigid segments based on Ixochemical. The resin has a glass transition temperature of 265-}-270°C and a continuous use temperature of 220-230°C. Polyurethane grade Gfone T-PSS itself has low smoke density and good flame retardant properties and has therefore been used in engine coils. Not only that, but also found that it can be applied in aerospace and automotive circuit packaging. The currently available Gafone T6300 grade polyethersulfonphthalein is a transparent product of Mosquito color and is a universal injection molding and extrusion molding resin. Another new grade is B-PSS, a polyether hydrazine used as a food packaging container developed for the replacement of polyether imide (PEI), which has a glass transition temperature of 224°C and a continuous use temperature of 180°C. 0C: The notched impact strength was 7. 1 kJ/m, which is higher than that of the general polyether antimony. In addition, the resistance to stress cracking and the ability to form heat-resistant pressure tanks are also high.
