## Conductive PS compound Frequently Asked Questions (FAQ)

    **

    **Q1：导电PS复合材料有什么功能？**

A：它是以聚苯乙烯（PS）为基体的导电复合材料，兼具抗静电与电磁干扰（EMI）屏蔽功能。

**Q2：导电PS的表面电阻率是多少？**

A：表面电阻率范围为 10⁴~10⁹ Ω/sq，可根据不同应用需求，通过调整导电填料的种类与用量获得不同导电性能。

**Q3：导电PS的耐热性能如何？**

A：其玻璃化转变温度与熔点较低，热稳定性较差，耐热范围一般在 70℃~100℃ 左右。温度接近或超过玻璃化转变温度时会出现硬度下降、尺寸稳定性变差，因此不建议用于高温环境或耐热要求高的场景。

**Q4：导电PS用在哪些领域？**

A：包括半导体包装材料、抗静电添加剂、电脑抗电磁屏幕、智能窗户、太阳能电池、手机与微型电视屏幕，以及电气工程中的电机槽绝缘与相间绝缘、电容器/变压器/电线电缆包装绝缘，还有电子产品的电磁屏蔽外壳与屏蔽罩等。

**Q5：导电PS可以采用哪些加工方式？**

A：可通过注塑、挤出、吹塑等加工方式，制成 PS 片材、板材、管材及注塑件等不同形状的制品。

**Q6：导电PS的耐化学性如何？**

A：耐化学性良好，可耐受大多数化学品，能抵抗部分酸、碱、盐及其他化学品的侵蚀，尤其适合半导体包装材料。
