Raw Material Calcium Zinc Stabilizer

Calcium Zinc Stabilizer Properties and Applications

1. It has good lubricity and unique coupling effect, endows the filler with good dispersibility, improves the wrapping with resin, improves the product performance, reduces mechanical wear and prolongs the service life of the equipment
2. It can give PVC mixture good uniform plasticizing and high speed melting fluidity, making the product surface smooth.
3. Excellent initial whiteness and thermal stability, resistant to sulfur pollution
4. It can replace organic tin stabilizer and lead salt stabilizer to meet the environmental protection and health requirements of non-toxic wire and cable.
5. Both toughening and melting promotion, good plasticizing fluidity

Because of the characteristics of calcium zinc stabilized materials they are widely used in many flexible and rigid PVC applications. This type of stabilizing system can give products which have a high degree of clarity, good mechanical and electrical properties, excellent organoleptic properties and good outdoor weatherability.

Practical application considerations

1. Confirm the green environmental protection of calcium and zinc stabilizer formula: it is necessary to pay attention to whether the content of heavy metals (lead, cadmium, tin, barium) can meet the requirements of the new national standards
2. Calcium and zinc stabilizer internal lubrication, the addition of external lubricant to more
3. Attention should be paid to the cleaning cycle during the operation process. The addition of calcium and zinc stabilizer lubricants will easily lead to the increase of precipitation, which will affect the cleaning cycle.For large – scale production of greater impact, to strictly select the stabilizer varieties.If it is their own stabilizer, need to cooperate with the late lubrication effect of PE wax or oxidized wax.Also strictly control the vacuum degree, can reduce precipitation, extend the cleaning time of the mold.
