Description
Calcium stabilizers, also known as calcium-based stabilizers or calcium-zinc stabilizers, are additives used in the PVC (polyvinyl chloride) industry to stabilize PVC against thermal and UV degradation. These stabilizers are typically composed of calcium, zinc, and other additives.
Some key points about calcium stabilizers include:
- Stabilization: Calcium stabilizers are used to stabilize PVC during processing and long-term use. They help prevent PVC from degrading due to heat, light, and other environmental factors.
- Environmentally Friendly: Calcium stabilizers are considered more environmentally friendly than lead-based stabilizers, which were commonly used in the past but have been phased out due to environmental concerns.
- Cost-Effective: Calcium stabilizers are often more cost-effective than other types of stabilizers, making them a popular choice in the PVC industry.
- Compatibility: Calcium stabilizers are compatible with a wide range of PVC formulations and processing conditions, making them versatile and easy to use.
- Regulatory Compliance: Calcium stabilizers comply with regulatory requirements for PVC stabilization, including restrictions on heavy metals such as lead and cadmium.
