The production of high-quality PVC foam products, such as foam boards and profiles, requires precise control over several processing parameters. Among the critical additives employed, high-viscosity ACR processing aids play a pivotal role in achieving desired cellular structures, low densities, and enhanced mechanical properties. NINGBO INNO PHARMCHEM CO.,LTD., a prominent manufacturer and supplier, specializes in providing these advanced solutions to the plastics industry. This article delves into the benefits and applications of high-viscosity ACR processing aids for foam PVC applications.

The Crucial Role of High-Viscosity ACR in PVC Foaming

During the PVC foaming process, blowing agents generate gas cells within the molten polymer. High-viscosity ACR processing aids are specifically designed to stabilize these nascent cells, preventing their collapse and ensuring a uniform cellular structure. They enhance the melt elasticity and strength of the PVC compound, allowing it to stretch and encapsulate the gas bubbles effectively. This leads to:

  • Reduced Foam Density: By creating and stabilizing more cells, high-viscosity ACR contributes to lighter-weight PVC foam products, a key requirement for many applications like construction materials and insulation.
  • Increased Impact Strength: A well-formed cellular structure improves the impact resistance of the foam, making products more durable and less prone to cracking.
  • Improved Surface Quality: These aids contribute to a smoother, more uniform surface finish on foam boards and profiles, enhancing their aesthetic appeal.
  • Enhanced Processability: High-viscosity ACR aids in achieving a broader processing window, making extrusion more controllable and efficient for manufacturers.
