In terms of controlling the pore structure:

Uniformity of foam pores: High viscosity foam modifiers can disperse the foaming agent more evenly in the polymer matrix, ensuring uniform size and distribution of the formed foam pores.

Bubble stability: High viscosity helps increase the strength of the melt, making it less likely for bubbles to break or merge during formation and growth. This can ensure that the bubbles can maintain their independent shape, improve the porosity and thermal insulation, sound insulation and other properties of the foam board.

In terms of improving mechanical performance:

Strength Enhancement: High viscosity foaming modifiers can interact with polymer molecular chains to enhance entanglement and cross-linking between molecules, thereby improving the mechanical properties such as tensile strength, bending strength, and impact strength of foam boards.

Dimensional stability: Due to the high viscosity foaming regulator's ability to improve the strength and stability of the melt, it can reduce the dimensional deviation of the foam board caused by changes in temperature, pressure, and other factors during the production process.

In terms of improving processing performance:

Extrusion stability: In the extrusion production process of foam boards, high viscosity foaming modifiers can improve the fluidity and stability of the melt, making the extrusion process smoother.

Plasticization effect: High viscosity foaming modifiers can promote the plasticization of polymers, allowing them to achieve good plasticization effects at lower temperatures.

In terms of product quality and cost control:

Product quality improvement: By improving the cell structure, mechanical properties, and processing stability, high viscosity foaming modifiers can significantly enhance the overall quality of foam boards.

Cost savings: Although the price of high viscosity foaming modifiers may be relatively high, their usage is usually limited to achieve better results.
