1、电绝缘性（尤其高频绝缘性）优良，白色硬而脆，跌落于地上有金属响声,透光率仅次于有机玻璃,耐水性,化学稳定性良好。有优良的阻燃性，为不燃塑料。 宋体;color:#444444;mso-font-kerning:1.0pt;mso-ansi-language:EN-US;mso-fareast-language: ZH-CN;mso-bidi-language:AR-SA">
2、强度一般刚性很好，但质脆，易产生应力脆裂；不耐苯、汽油等×××；长期使用温度可达260度；在400度的空气或氮气中保持稳定。通过加玻璃纤维或其它增强材料改性后，可以使冲击强度大为提高耐热性和其它机械性能。密度增加到1.6-1.9，成型收缩率减小到0.15-0.25％ 适于制作耐热件、绝缘件及化学仪器、光学仪器等零件。 mso-fareast-font-family:宋体;color:#444444;mso-font-kerning:1.0pt;mso-ansi-language: EN-US;mso-fareast-language:ZH-CN;mso-bidi-language:AR-SA">
