Why Do Sealing Rings Need to Be Added to the Waterproof Distribution Box?

Can ZCEBOX plastic waterproof junction boxes be used outdoors? The sealing ring plays an important role in the protective function of the waterproof junction box and provides good protection for its waterproof performance. During long-term use, the continuity of the protection level depends on the characteristics of the sealing ring. When foam is accurately injected, the polyurethane seal will stay firmly in place. Due to its excellent chemical resistance and corrosion resistance, EPDM material provides good protection against most commonly used chemical substances. The chemical resistance of sealing ring materials varies greatly, so directly testing the reaction between the chemical composition and the sealing ring is an effective method to confirm the required effect.

The performance of a waterproof distribution box varies according to the materials used for different sealing rings. The material and cross-sectional profile of the sealing ring determine the protection level of the electrical junction box. The selection of seals is based on comparing the elasticity of individual material components, their resistance to contact with various chemicals, and their performance under heat and cold. It is important that the waterproof distribution box and the sealing ring have common resistance to the same chemical substances to achieve good results.
