性能:
  有較好的透明性。力學強度也較高,有一定的耐熱性,耐寒性和耐氣候性、耐腐蝕,絕緣性良好。制品尺寸穩定,成形容易。缺點是質較脆,易溶于有機溶劑中,作為透光材料,表面硬度不夠、容易擦毛,就其綜合性能來看,超過聚苯乙烯等一般塑料。
用途:
  用來制造一定透明度和強度的零件,如油標、油杯,光學鏡片、透鏡、設備標牌、透明管道、汽車車燈及晶體管收音機刻度盤及電氣絕緣零件等。

Performance:
Better transparency. High mechanical strength, a certain heat resistance, cold resistance and weather resistance, corrosion resistance, good insulation. Articles dimensionally stable, easy to mold. The disadvantage is more brittle substance, soluble in organic solvents, as the translucent material, the surface hardness is not enough, easy to rub the hair on its overall performance point of view, than the general polystyrene plastic.
Purpose:
Used to make certain parts of transparency and strength, such as Standard Oil, oil cup, optical lenses, lens, equipment, signs, transparent pipes, automobile headlights and a transistor radio dial and electrical insulation parts.
