Description
Liquid mixed metal stabilizers (LMMS) are a type of stabilizer used in the processing of PVC (polyvinyl chloride) and other chlorinated polymers. They are composed of a mixture of metal salts, typically containing calcium, zinc, and magnesium, in a liquid form.
Some key points about liquid mixed metal stabilizers include:
- Stabilization: LMMS are used to stabilize PVC and other chlorinated polymers against heat, light, and other environmental factors that can cause degradation. They help maintain the mechanical and physical properties of the polymer during processing and long-term use.
- Efficiency: LMMS are known for their high efficiency in stabilizing PVC, requiring lower dosages compared to other types of stabilizers.
- Processing Benefits: LMMS can improve the processing characteristics of PVC, such as melt flow and thermal stability, making them beneficial in PVC processing operations.
- Compatibility: LMMS are compatible with a wide range of PVC formulations and processing conditions, making them versatile and easy to use.
- Regulatory Compliance: LMMS are generally considered safe for use in PVC and comply with regulatory requirements for PVC stabilization.
