PVC Exothermic Foaming Agent MSV-513 Yellow Powder for PVC Shoe Materials, Low Foam Boards, Profiles, and WPC Doors

Product Principle：
MSV-513 is a high-purity exothermic foaming agent that decomposes at 165–185°C, releasing gas to support uniform cell growth in PVC. Its 4–6 um ultrafine particles ensure excellent dispersion and stable nucleation, forming fine closed-cell structures with good mechanical properties, low density, and smooth surfaces.

Performance Characteristics：
MSV-513 has a gas volume of 170–200 ml/g and 97% purity, offering stable foaming and strong weight reduction for shoe materials and low-foam products. With ultra-low sieve residue (0.1%) and low volatiles (≤3%), it enables clean processing. Its 4–6 um fine particles disperse well, and decomposition temperature matches standard PVC processing conditions.

Usage and Dosage：
Recommended dosage: 0.5–3% based on foam density, cell structure and application; 1.5–2.5% for PVC shoe materials, 0.8–1.8% for low-foam boards and profiles, with optimization via trials.

1. Exceptional Foaming Efficiency：
With 170–200 ml/g gas volume, MSV-513 delivers outstanding expansion capability, enabling significant weight reduction of 15–30% in PVC shoe materials and low foam products while maintaining structural integrity.

2. Fine, Uniform Bubble Structure：
The ultra-fine particle size and controlled decomposition produce exceptionally fine and evenly distributed bubbles. This uniform cell structure enhances mechanical properties and contributes to superior surface quality in finished products.

3. Smooth Surface Finish：
Unlike conventional foaming agents that can cause surface roughness or defects, MSV-513 produces foamed products with exceptionally smooth surfaces. This eliminates the need for additional finishing operations and enhances aesthetic appeal.

4. Ultra-Fine Particle Size for Uniform Dispersion：
The 4–6 μm fineness ensures rapid, homogeneous distribution throughout PVC compounds, eliminating localized density variations and ensuring consistent foam properties across all product sections.

5. Clean Processing Profile：
High purity (97%) and minimal residue (0.1% on sieve) ensure clean decomposition without die buildup, plate-out, or surface defects. This enables longer production runs and consistently high-quality finished products.

6. Optimal Decomposition Temperature Range：
The 165–185°C decomposition range aligns perfectly with PVC processing temperatures for both shoe materials and low foam extrusion, ensuring gas release occurs at the optimal moment for cell nucleation and growth.

7. Versatile Application Compatibility：
MSV-513 performs effectively across diverse applications, from flexible shoe materials to rigid low foam boards and profiles, simplifying formulation development and inventory management.

8. Enhanced Product Aesthetics：
The combination of fine bubble structure and smooth surface finish produces products with superior visual appeal, meeting the demanding requirements of consumer-facing applications.

1. PVC Shoe Material Production：
MSV-513 is specifically formulated for PVC shoe components, delivering lightweight, comfortable foams with fine bubble structures and smooth surfaces. It enhances the cushioning properties of insoles, midsoles, and other footwear components while maintaining durability.

2. PVC Low Foam Boards：
In low foam board applications for signage, displays, and construction, MSV-513 produces uniform cell structures that reduce weight while maintaining the smooth, printable surfaces essential for high-quality graphics and finishes.

3. PVC Low Foam Profiles：
For extruded profiles requiring both lightweight construction and excellent surface appearance, MSV-513 delivers the foaming performance needed for consistent quality and visual appeal in trim, moldings, and decorative applications.

4. Foamed Sheet Extrusion：
In PVC foam sheets for packaging, insulation, or thermoforming, MSV-513 ensures uniform cell distribution and smooth surfaces that enhance formability and finished product appearance.

5. Lightweight Rigid Components：
For rigid PVC parts requiring weight reduction without compromising surface quality, MSV-513 provides the controlled foaming necessary for consistent performance and aesthetics.

6. Decorative Moldings and Trim：
In architectural moldings and decorative trim where surface appearance is critical, MSV-513 produces the smooth, defect-free surfaces essential for painting and finishing operations.

7. Co-extruded Foam Products：
For products with solid skins and foamed cores, MSV-513 enables precise control over core density while maintaining excellent adhesion between layers and smooth outer surfaces.

8. Specialty PVC Applications：
In any PVC application where the combination of weight reduction, fine cell structure, and superior surface quality is desired, MSV-513 provides the performance advantage needed for premium market positioning.
