Nylon vs polyester slings: which performs better in high heat environments?

CQ-019 · Rigging
Polyester slings perform better in high heat, maintaining strength up to 200°F while nylon degrades rapidly above 180°F.
Polyester synthetic slings significantly outperform nylon in high-temperature applications. Polyester maintains its rated capacity at temperatures up to 200°F (93°C), while nylon slings begin losing strength at 180°F (82°C) and should not be used above this temperature. At 200°F, nylon slings lose approximately 25% of their rated capacity.
Reference: ASME B30.9 - Slings Standard
Remember: "Poly stays strong when temps get long, Nylon wilts when heat hits 180"
