Why does the insulation cable show the different insulation property when using different calcium and zinc stabilizers ?
Mainly because of the raw materials of the stabilizers are different.
Cable materials required insulation properties generally use powdered calcium-zinc stabilizers.
The normal raw materials used for powdered calcium-zinc stabilizers are calcium stearate, zinc stearate, hydrotalcite, calcium acetylacetonate, and calcium & Zinc acetylacetonate,betadione, antioxidant, phosphite, etc.
Nowadays, the calcium and zinc stabilizer market is fiercely competitive. Some added zeolite, calcium oxide, and other strong alkaline materials in the calcium and zinc stabilizer. These strong alkaline materials are good conductors of electricity, although such calcium and zinc stabilizers Stabilizers can also produce cable materials and wires, but their insulation properties will be greatly reduced.
This is the based reason why the insulation properties are so different.
Please make sure with supplier that The calcium-zinc stabilizer uses hydrotalcite, no zeolite, calcium hydroxide, calcium oxide, and so on.
