Composite heat calcium zinc stabilizer without sulfide contamination enviromental friendly
Product Features:
1. Environmental friendly products
No heavy metal elements (lead, septum), no toxic and hazardous substances, can meet the requirements of the latest environmental standards of various countries (such as the EU RHOS Directive, REACH Directive, etc.).
2. No sulfur contamination
Products using lead salt stabilizers are prone to sulfur contamination in the presence of sulfur (such as acid rain, packaging boxes), causing yellowish discoloration or even blackening of white products, seriously affecting the appearance. Calcium and zinc stabilizers do not appear to behave like this
3. Good thermal stability
With the continuous development and improvement of calcium-zinc stabilizers, it can basically replace the lead-salt composite stabilizer with 1:1 to ensure the production cycle and stability. After the cooling of the die, the material decomposition will become quite slow.
4. Good system switching characteristics
Calcium-zinc heat stabilizers do not react with lead salts, organotin and other heat stabilizers, will not cause pollution, and have low switching costs, and will not affect the use of small tubes, plastic steel and other recycled materials.
5. The product has no smell
PVC products produced by calcium-zinc stabilizers do not produce odors with organotin, which is more acceptable to the public.
6. Low density, can increase the amount of calcium carbonate, reduce costs.
The calcium-zinc heat stabilizer itself has a lower density than the lead salt stabilizer, and the PVC product only has a decrease in the weight of the heat stabilizer.
7. Promote foaming, reduce density
The raw material of calcium-zinc stabilizer, zinc stearate can promote the decomposition of the foaming agent, make the foamed product more delicate, and the density becomes smaller, and even more, the dosage of the adjusting agent can be reduced, and the cost is saved.
8. To prevent the generation of black lines
Although the organotin stabilizer has good thermal stability, it does not have lubricity and plasticization is easy to produce black wire (drag black). The calcium-zinc stabilizer has self-lubricating properties and plasticization is adjustable, which can effectively prevent The generation of black lines caused by problems such as equipment and plasticization.
