、without modification of polyphenylene oxide (ppo) resin has good mechanical properties, electrical properties, heat resistance, flame resistance&chemical stability, but its poor solvent resistance&products are prone to stress cracking, low impact strength, it also has a fatal weakness -- high melt viscosity, processing range, cannot adopt pure ppo resin injection molding, which greatly s its application.、(2) ppsdr、 、abs classification:、as mentioned before, glass reinforced ppa resin has a high hdt value, which can tolerate short term effects of high temperature, for example, in a furnace,/in steam phase&in the process of infrared countercurrent consolidation. the thermal oxidation stability of ppa resin makes it capable of long-term high temperature effect&glass enhancement ppa. within 20000 hours, its continuous use temperature can reach 330 f.、elongation (fracture) 3% astm d638
