1. Product Overview & Specifications

Manganese Stearate (CAS 3353-05-7) is a metal carboxylate compound with the chemical formula Mn(C₁₈H₃₅O₂)₂. This pale pink powder exhibits exceptional thermal stability and lubricating properties, serving as a multifunctional additive across industries.

2. Key Applications & Industrial Uses

2.1 PVC Stabilization

Acts as cost-effective secondary stabilizer in rigid PVC formulations, demonstrating superior synergy with primary lead-based or calcium-zinc stabilizers.

2.2 Rubber Compounding

Enhances mold release characteristics in EPDM and SBR compounds while functioning as internal lubricant (0.5-1.5% loading recommended).

3. Technical Performance Advantages

• 20% higher thermal stability vs. conventional metal stearates
• Reduces extrusion torque by 15-25% in PVC processing
• 0.8-1.2 g/cm³ bulk density for optimal dispersion

4. Industry Application Scenarios

4.1 Wire & Cable Manufacturing

In 70°C-rated PVC insulation compounds, 0.8 phr loading improves flow properties while maintaining 120-minute thermal stability.

4.2 Automotive Seals Production

Enables 15% cycle time reduction in EPDM weatherstrip vulcanization through improved mold release performance.
