FAQ
1. Q: EPDM vs. Nitrile (NBR) – Which to choose?
A: EPDM excels in weather/steam resistance; NBR is better for oils/petroleum.
2. Q: Can EPDM handle silicone grease?
A: Yes, but avoid petroleum-based lubricants, which may swell the material.
3. Q: Lead time for custom sizes?
A: 15-20 days for tooling + production.
