PPS 和 PPA、PA46 区别是什么?

PPS (聚苯硫醚) 耐温 200-240°C、阻燃 V-0 (本征阻燃, 不加阻燃剂)、耐化学极佳 (仅次于 PTFE)、价格中等。PPA 耐温 180°C、PA46 耐温 150°C。汽车涡轮增压器、电气绝缘首选 PPS (耐高温 + V-0 + 尺寸稳定)。

PPS 玻纤增强常见规格和典型应用?

PPS GF40% (40% 玻纤, 如 DIC FZ-1140) 是性价比平衡点, 用于汽车连接器、传感器外壳; GF65% (如 Celanese 1165) 用于精密齿轮、轴承保持架; PPS + 碳纤维用于耐磨件。

PPS 能用在食品接触吗?

通用 PPS 不推荐食品接触; 食品级 PPS (如 Toray A604-X95) 通过 FDA 21 CFR 176.170。PPS 耐热 + 耐化学, 适合微波炉内胆、不粘锅涂层基材、咖啡机热水管。但成本高 (¥200-300/kg), 通常用 PPS 涂层而非纯料。
