Frequently Asked Questions

Q: What materials are best for lithium battery equipment seals?

For lithium battery manufacturing equipment, FKM (Viton) or Silicone are recommended due to their superior chemical resistance and ability to withstand extreme temperatures without degrading.

Q: Can these adhesive strips be customized for industrial battery storage systems?

Yes, we provide full OEM services. We can customize the profile, hardness (30-85 Shore), and material to ensure a perfect seal for Battery Energy Storage Systems (BESS).

Q: How does EPDM rubber differ from standard PVC in automotive use?

EPDM offers significantly better UV resistance, ozone resistance, and thermal stability compared to PVC, making it the industry standard for outdoor automotive weatherstripping.

Q: What is the minimum order quantity (MOQ) for custom mold designs?

Our standard MOQ is 100 meters. This allows us to maintain quality control while providing competitive pricing for custom-engineered profiles.

Q: Are these seals suitable for high-temperature environments like ovens or labs?

Absolutely. Depending on the material selected (such as Silicone or FKM), our seals can withstand temperatures up to 300ºC, making them ideal for disinfection cabinets and laboratory ovens.

Q: How do the internal metal clips improve the installation?

The internal aluminum clips provide a mechanical lock onto the car door edge, preventing the strip from peeling or shifting over time, which is a common failure point in adhesive-only strips.
