Mixed Metal Stabilizer

Description

Mixed Metal Stabilizer is a customized blend of multiple metal-based components such as calcium, zinc, magnesium, aluminum, and sometimes barium or tin. These stabilizers are designed to meet special performance requirements that single-metal systems cannot fully support.

They are often used when thermal, electrical, weathering, or processing demands are complex, such as in multi-layer films, automotive cables, or weather-exposed profiles.

Unlike standard stabilizers, Mixed Metal systems are usually tailored per customer formulation, offering flexibility in compatibility, stability, and regulatory compliance.

Usage Recommendations

Application Need	Mixed Metal Stabilizer Role
Need better weather resistance than Ca-Zn	Add Mg or Ba for UV and heat synergy
Transparent + tough compound	Use Al-Zn-Ca blend to reduce haze
Complex cable with high filler	Adjust metal ratio to prevent migration
RoHS-compliant but high strength required	Low-lead MM blend with stabilizing co-agents
Long extrusion runs with tight tolerance	Improves die stability and prevents plate-out

FAQ

Q1: What’s the difference between Mixed Metal and Ca-Zn stabilizer?
Mixed Metal uses more than two metal salts to optimize performance for specific needs. Ca-Zn is a subset of MM.

Q2: Is this product standard or custom?
Most MM stabilizers are tailored to your PVC formula, line speed, color, and end-use.

Q3: Is it lead-free?
Yes, lead-free or low-lead versions are available. Full documentation is provided.

Q4: Can I use this in clear PVC?
Yes, with special grades that maintain transparency.

Q5: How do I choose the right metal blend?
Our technical team will evaluate your resin type, process, and application to recommend the optimal MM formula.
