Environmental Protection Calcium Zinc Stabilizer
Environmental Protection Calcium Zinc Stabilizer is composed of calcium zinc metal soap and high quality hydrotalcite and other functional additives. While improving the whiteness of PVC products, it does not reduce the mechanical properties of products and extend the driving cycle.
It is divided into flake stabilizer and powder stabilizer.
Product Description
Shitong Calcium Zinc Stabilizer is a PVC heat stabilizer formulated with calcium-zinc metal soaps, hydrotalcite and selected functional additives. It is designed to provide thermal stability during PVC processing while helping maintain good initial color, whiteness and processing performance.
Available in powder and flake forms, our Ca Zn stabilizers can be used in different rigid and semi-rigid PVC formulations, including PVC foam boards, profiles, pipes, wall panels and flooring products.
PVC can undergo thermal degradation when exposed to the high temperatures required during extrusion, calendaring or other processing operations. A suitable heat stabilizer helps reduce this degradation and maintains more stable material performance throughout production.
Calcium zinc stabilizers can help:
● Improve PVC heat stability during processing
● Maintain initial color and product whiteness
● Reduce discoloration caused by thermal degradation
● Improve processing stability during continuous extrusion
● Support stable mechanical properties of finished PVC products
● Improve compatibility with modern lead-free PVC formulations
● Extend the stable processing window of the PVC compound
The correct stabilizer system depends on the PVC resin, processing temperature, formulation and final product requirements.
Calcium zinc stabilizers can be incorporated into PVC foam board formulations to provide thermal stability throughout extrusion and foaming. They are suitable for advertising boards, furniture boards, bathroom cabinet boards and other foamed PVC sheets.
For window profiles, decorative profiles, wall panels and other extruded PVC products, the stabilizer helps maintain stable processing and initial color during continuous extrusion.
Calcium-zinc stabilizer systems are widely used in PVC profile applications where processing stability, color retention and weathering-related performance are important considerations.
Ca Zn stabilizers can also be selected for rigid PVC pipe and fitting formulations. The specific stabilizer grade should be matched to extrusion conditions, formulation composition and the performance requirements of the finished pipe.
PVC flooring formulations may require different stabilizer performance depending on whether the material is used in the core, backing or other layers. Calcium-zinc stabilizers can support heat stability, dispersion and processing performance in suitable flooring formulations.
For compact or foamed PVC sheets, an appropriate stabilizer system helps maintain heat stability and processing consistency. Calcium/zinc stabilizers are among the stabilizer systems used for these applications.
Shitong supplies Calcium Zinc Stabilizer in two physical forms:
Powder grades are suitable for PVC manufacturers using dry-blend mixing systems and can be easily incorporated with PVC resin, calcium carbonate, processing aids and other additives.
Flake stabilizers provide an alternative supply form for manufacturers with different feeding, handling and compounding requirements.
The appropriate form should be selected according to the customer's production equipment, formulation and mixing process.
Calcium zinc stabilizers are commonly selected as an alternative to traditional lead-containing stabilization systems in modern PVC formulations.
| Factor | Calcium Zinc Stabilizer | Traditional Lead Stabilizer |
|---|---|---|
| Main Stabilizing Metals | Calcium and zinc | Lead compounds |
| Lead Content | Lead-free system | Contains lead compounds |
| PVC Processing | Suitable for a wide range of modern PVC formulations | Traditionally used for rigid PVC |
| Color Requirements | Can provide good initial color and whiteness | Depends on stabilizer system |
| Typical Applications | Profiles, sheets, flooring, pipes, foam boards | Pipes, profiles and other rigid PVC products |
| Selection | Must be matched to formulation and processing conditions | Must also be matched to formulation |
Actual regulatory suitability depends on the specific stabilizer grade, formulation and target market. Customers requiring specific environmental or regulatory compliance should confirm the relevant technical documentation before ordering.
Shitong supplies PVC additives for manufacturers of PVC boards, profiles, flooring, pipes and other plastic products.
In addition to Calcium Zinc Stabilizer, Shitong supplies foaming regulators, processing aids, lubricants, impact modifiers and blowing agents, allowing PVC manufacturers to source multiple additives for formulation development and production.
For customers developing a new PVC formulation or replacing an existing stabilizer system, our team can recommend a suitable product according to your application and processing requirements.
A calcium zinc stabilizer is a heat stabilizer based primarily on calcium and zinc compounds. It is added to PVC formulations to help protect the material against thermal degradation during processing.
No. Calcium-zinc stabilizer systems are used in a range of rigid and flexible PVC applications. The exact formulation and stabilizer grade should be selected according to the final product and processing technology.
No. A stabilizer primarily protects PVC against thermal degradation, while lubricants mainly control friction, melt flow and metal release during processing. Some one-pack stabilizer systems may also provide a degree of lubrication, but the two functions should not be considered identical.
Yes. Shitong Calcium Zinc Stabilizer is available in both powder and flake forms.
