What is the difference between flame-retardant insulated PVC electrical sleeve and PVC conduit?

The flame retardant is added to the flame retardant insulation PVC material. At high temperature, the flame retardant will decompose, and part of the decomposition is water, which can effectively prevent combustion. Ordinary PVC conduit does not have this function.

Flame retardant insulation PVC is used to protect wire sleeves, and has requirements for flame retardant (fire resistant) insulation (electrical performance/electrical breakdown).

PVC casing can be used in many places, such as common drainage pipes.
