When it comes to heat resistance, not all nylons are created equal. As a customer, you care about what your end product will face, so here’s the hard truth, explained:
1. Continuous Operating Range
Standard PA6 and PA66 perform well up to 120–150 °C under continuous load, but beyond that, you’ll often see mechanical breakdown. If your application involves long-term heating, these may not be enough.
2. High‑Temperature/Heat‑Resistant Nylon
Specialty nylons like PA46, PA6T/9T, semi-aromatic/copolymer grades push continuous use into the 150 – 180 °C zone—some PA46 grades handle up to 180 °C continuously.
3. Extreme Heat Options (Semi-Crystalline PA)
For ultra-high-temp needs, semi-aromatic nylons (like PA6T/PPA) can tolerate up to 200 °C+ continuous. Their heat deflection temperature (HDT) can reach >280 °C.
What This Means for You:
Need under 150 °C? Standard PA66 works well, with balanced performance, cost-effective.
Need 150–180 °C? Opt for PA46 or PA6T grades—great for under-hood and industrial equipment.
Need >180 °C? Choose semi-aromatic high-temp nylons for top-tier heat and dimensional stability.
Customer Tip:
“Will my component stand up to sustained heat?”
Ask yourself:
- What’s my product’s typical temperature?
- Under what load or stress?
- For How Long?
Once you have the answers, match them to the nylon class above. We’re here to help you pick the right grade and even customize blends to meet your exact spec, without risking heat damage or warpage.
By clearly mapping temperature needs to material grades, you’ll gain confidence and avoid costly failures. Need help selecting or testing? Just reach out.
