What should buyers check when choosing 70°C PVC insulation compound?
For common building wires and hook-up wires, buyers should check processing stability, insulation performance, color, hardness and the applicable standard.
70°C PVC insulation compound is widely used for building wires, hook-up wires and general power cords. It affects electrical performance, surface appearance and production stability.
Confirm the finished cable standard first. If certification or customer inspection is required, the formulation should be matched to the target standard.
Processing stability is important for continuous extrusion. A suitable compound should plasticize evenly, keep a stable diameter and reduce surface defects.
Color and hardness should be controlled by sample or color code. Batch color difference can affect the finished cable appearance.
Environmental, odor or flame-retardant requirements should be stated before sampling, because they may require a different additive system.
