常见问题

What IP rating can silicone junction box seals achieve?

Properly designed silicone seals can achieve IP68 protection when correctly installed with appropriate compression.

How long do silicone seals typically last in industrial environments?

High-quality silicone seals can last 10-15 years in standard industrial conditions, depending on temperature, chemical exposure, and UV radiation.

Can silicone seals be used with oil or chemical exposure?

Silicone has good resistance to many chemicals but may swell with certain oils; specialized formulations are available for specific chemical resistance.
