PVC WPC DOOR Foaming Agent white powder MS-107

Product Principle：
MS-107 contains 90% sodium bicarbonate, which decomposes endothermically within the temperature range of 155–170°C, absorbing heat and releasing carbon dioxide gas. This endothermic reaction cools the polymer melt, preventing overheating and stabilizing the foaming process. When used alongside exothermic foaming agents such as AC, MS-107 balances the overall thermal profile, reducing the risk of cell coalescence and ensuring uniform bubble formation throughout the extruded profile.

Performance Characteristics：
With a gas formation volume of 150–170 ml/g, MS-107 provides reliable foaming power while its endothermic nature delivers significant processing advantages. The low volatile content (2.5%) and minimal fugitive constituents (≤3%) ensure clean decomposition without excessive smoke, odor, or die buildup. The fine white powder disperses readily in PVC compounds, promoting consistent cell nucleation. Its compatibility with both NC and AC foaming agents allows formulators to fine-tune foam structures for specific pipe and profile applications.

Usage and Dosage：
Recommended addition level is 0.5–3 phr, typically used in combination with 0.1–0.5 phr of AC or NC foaming agents. The exact ratio depends on the desired foam density, cell structure, and wall thickness of the product. For thick-walled pipes requiring uniform internal foam, higher MS-107 proportions are beneficial. Systematic trials are recommended to optimize the blend for specific applications and processing conditions.

1. Endothermic Decomposition for Thermal Stability：
MS-107 absorbs heat during decomposition, actively cooling the polymer melt. This prevents localized overheating that can cause cell collapse or surface degradation, particularly beneficial in thick-walled products like pipes where heat dissipation is challenging.

2. Synergistic Performance with Exothermic Agents：
When combined with AC or NC foaming agents, MS-107 balances the exothermic heat release, resulting in smoother foam expansion, finer cell structures, and reduced risk of blowholes or surface defects.

3. Enhanced Structural Stability：
The uniform cell structure promoted by MS-107 improves the mechanical integrity of foam pipes and profiles. Products exhibit higher crush resistance, better dimensional stability, and more consistent mechanical properties throughout the cross-section.

4. Clean Processing and Reduced Die Buildup：
Low fugitive constituent and volatile content ensure clean decomposition with minimal residue accumulation on processing equipment. This enables longer production runs, reduced maintenance downtime, and consistently high surface quality.

5. Versatile Formulation Compatibility：
MS-107 works effectively with various foaming agent systems and is compatible with both rigid and flexible PVC formulations, providing formulation flexibility for diverse product requirements.

1. PVC Foam Pipes：
MS-107 is specifically formulated for multi-layer or co-extruded foam pipes, where it helps achieve a uniform core layer with reduced density and consistent cell size. It is particularly valuable in drainage, sewage, and conduit pipes where weight reduction and cost savings are priorities.

2. Foam Profiles：
In window profiles, decorative trim, and construction moldings, MS-107 contributes to lightweight construction while maintaining surface quality, strength, and dimensional accuracy.

3. Foam Sheet Extrusion：
For foam sheets used in packaging, signage, or insulation, MS-107 provides the thermal control needed for flat, warp-free panels with uniform cell distribution.

4. Complex Extrusions with Varying Wall Thickness：
In profiles with sections of different thicknesses, MS-107 ensures uniform foaming across all areas, preventing density variations and maintaining consistent mechanical properties.

5. Co-extruded Foam Core Products：
For products with solid skins and foamed cores, MS-107 enables precise control over core density while maintaining excellent adhesion between layers.
