MK-304 PVC Foaming Regulator

Raw Materials & Manufacturing Process

MK-304 is produced from high-molecular-weight acrylate elastomer monomers through emulsion polymerization to form a specialized high melt strength polymer. It is then processed by dehydration, drying, and ultra-fine pulverization.

It is specifically designed for AC/ADC chemical foaming systems, providing strong melt support.

Product Functions & Key Advantages

• Strong Melt Strength Support:
  Effectively prevents cell collapse, rupture, coalescence, and formation of large or irregular bubbles
• Fine & Uniform Cell Structure:
  Produces dense and smooth skin layers, improving surface quality and flatness of foamed boards
• Improved Foaming Ratio:
  Optimizes cell structure, enhances dimensional stability, and reduces product weight
• Smoother Processing:
  Reduces extrusion torque and is suitable for high-speed foaming extrusion lines
• Excellent System Compatibility:
  Fully compatible with mainstream chemical foaming agents such as AC and ADC
