Hebei Messi Biology Co., Ltd. stated that magnesium carbonate as a filler in PVC cable granules has the effect of reducing formulation costs and playing an incremental reinforcement role in PVC compounding materials.
Secondly, magnesium carbonate has the function of adsorbing ions. It can reduce the free freeness of conductive ions in the PVC system, which can not only improve the insulation performance of the product volume resistivity, but also improve the thermal oxygen aging resistance of the cable material, as well as its thermal deformation and mechanical properties.
In addition, magnesium carbonate can also effectively improve the extrusion process performance and wire release performance of PVC cable granules. As for the amount of magnesium carbonate, it is closely related to the performance of low-temperature impact embrittlement, elongation, mass loss, etc.
The role of magnesium carbonate in cables is very important. It can not only improve the performance of the product, but also make the cable safer and more reliable to use.
