Material: Polyvinyl chloride (PVC), with the possibility of adding plasticizers, stabilizers, and flame retardants to enhance performance.

Electrical performance: high insulation resistance, excellent dielectric strength.

Mechanical performance: Good impact resistance and toughness. Different types (such as light, medium, and heavy) correspond to different compressive strengths.

Fire resistance: usually meets UL94 V0 or V2 flame retardant rating (V0 is the highest), with no or low melting droplets during combustion.

Chemical properties: Corrosion resistant to acid, alkali, salt, and various chemicals.

Environmental adaptability: Conventional models are not resistant to long-term ultraviolet radiation, while outdoor models require the addition of anti UV agents. The working temperature range is generally from -5 ° C to+60 ° C.

Design: Equipped with a snap on cover plate, easy to open and close, and secure after closure.
