Frequently Asked Questions

Q: What is the primary advantage of Silicone (VMQ) over NBR for rubber seals?

Silicone offers a significantly wider temperature operating range (-50°C to 230°C) and superior resistance to ozone, weathering, and aging compared to NBR.

Q: Can you manufacture rubber parts based on custom drawings?

Yes, we specialize in OEM manufacturing and custom rubber parts, utilizing advanced design and mold development capabilities to meet your exact specifications.

Q: What quality certifications do your rubber products hold?

Our factory and products are certified under ISO 9001 and ISO/TS 16949, and many of our seals also meet LFGB standards for food-grade safety.

Q: How do you ensure the stability of the material properties?

We use imported raw materials from world-class suppliers like DuPont and JSR, combined with a strict six-stage inspection process.

Q: What is the typical lead time for custom rubber gaskets?

For in-stock items, delivery is 2-5 workdays. For custom non-stock items, lead times typically range from 7-15 workdays depending on the quantity.

Q: Which material is best for high-temperature chemical resistance?

FKM (Fluorocarbon) is the best choice for extreme temperatures up to 320°C and offers the highest level of chemical and non-flammability resistance.
