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.

- What is heat stabilizer?
- Heat stabilizers are antioxidants that are used to reduce the degrading effects of heat generated during processing of the biopolymer composition under
severe conditions (shearing, temperature, and oxygen). From:
Biopolymers: Processing and Products, 2015.
- What is PVC stabilizer pack?
- A One Pack Stabilizer is a pack of additives added during the processing of PVC. ... Non-Toxic One Pack Stabilizers are based on Calcium, Zinc, and Barium that are blended with co-stabilizers and lubricants to make the product heavy metal free.
- What is stabilizer in plastic?
- Stabilizers are a class of chemical additives commonly added to polymeric
materials, such as plastics, to inhibit or retard their degradation.
- How much heat can PVC handle?
- Explanation: PVC is a thermoplastic, and therefore, at some point it will begin to degrade and break down as it's heated up. It just so
happens that Schedule 40 PVC's maximum operating temperature is 140 degrees Fahrenheit, around the same temperature that hot water gets to in most homes.
- Can PVC cause cancer?
- The PVC manufacturing process is highly poisonous, releasing dioxin and causing cancer. Dioxin is a highly toxic chemical, but its presence in the
environment has declined sharply in the last three decades. This
has occurred while PVC production has increased by 300 percent.
