peek的耐温度范围

  • Release time: 2026-08-13

PEEK(聚醚醚酮)的耐温度范围可按不同使用场景明确划分,不同形态的PEEK材料耐温性能略有差异:

连续长期使用温度‌:常规未增强PEEK的UL温度指数为‌250-260°C‌,可在该温度区间长期稳定保持力学性能与化学稳定性。
短期瞬时使用温度‌:可承受最高‌300°C‌的短时高温冲击,短时间内不会出现明显性能劣化。
基础特征温度‌:玻璃化转变温度为‌143-160°C‌,熔点为‌334-343°C‌,达到熔点后材料才会发生明显熔融形变。
增强改性型号提升‌:碳纤维或玻璃纤维增强的PEEK型号,热变形温度会进一步提升,耐温表现优于常规未增强板材、棒材产品。
