Why Do Unscrupulous Merchants Prefer To Use Non-flame-retardant Pvc As The Insulation Material For Copper Terminal Blocks?

Unscrupulous vendors typically use non-flame-retardant PVC as copper terminal block insulation material. This material is low-cost, simple to produce, and readily available. Compared to flame-retardant materials, PVC is cheaper, leading some irresponsible vendors to widely use non-flame-retardant PVC in the production of copper distribution block insulation materials to reduce production costs for copper terminal strip insulation materials. While PVC has some electrical insulation properties, its fire resistance is poor. In the event of a fire, it may exacerbate the spread of the fire, creating greater safety hazards.
