PVC Furniture Board Enhances Plasticization Foaming Regulator K400

Product Principle：

Adding foaming regulators K400 to low-foam PVC extruded products promotes PVC gelation, enhances melt thermal strength and elongation, improves surface quality, and stabilizes the fine pores formed by foaming agents. This prevents pore walls from rupturing and interpenetrating to form large voids, resulting in foam with both low density and high strength.

Performance Characteristics:

This PVC processing additive effectively promotes low-temperature melting and uniform plasticization of PVC, enhancing melt cohesion and homogeneity. It greatly improves melt strength, elongation, and elasticity, while reducing melt pulsation and instability for more stable processing. Featuring excellent dispersibility in PVC, this additive ensures smoother surfaces and high surface gloss, significantly improving overall product quality and appearance. It is an ideal additive for high-performance PVC foaming and extrusion applications.

Usage and Dosage：

The recommended addition level of this product is 5%–11% based on the total weight of the PVC formulation.

1. Enhanced Plasticization and Processing Efficiency：
Foaming regulator K400 functions as an efficient PVC processing aid to significantly promote the plasticization of PVC compounds. By accelerating the fusion rate of the resin under heat and shear, it reduces processing time and energy consumption. This ensures a homogeneous melt is achieved earlier in the extrusion or molding process, which is fundamental for subsequent foaming steps.

2. Improved Melt Strength and Foam Structure Optimization：
The regulator dramatically enhances the melt strength and elasticity of the PVC matrix. This increased melt tension effectively prevents the coalescence of bubbles during the foaming process, ensuring that gas cells remain stable and do not collapse. Consequently, it facilitates the formation of a uniformly distributed microcellular foam structure, resulting in products with consistent density and superior mechanical properties.

3. Enhanced Melt Flow and Surface Quality：
By improving the rheological properties of the PVC melt, K400 increases fluidity and processability. This reduction in melt fracture and die build-up allows for smoother extrusion. The improved flow characteristics directly contribute to a superior surface finish, eliminating imperfections such as sharkskin or matte appearances, and yielding products with a smooth, glossy, and aesthetically pleasing exterior.

1.PVC Furniture Boards：

PVC foaming regulator K400 is widely applied to the production of foam boards, including furniture boards, which are core components in modern interior design and furniture manufacturing. This additive ensures consistent foam structure and dimensional stability, making the boards lightweight yet durable for various applications.

2.PVC Cabinet Boards and Advertising Boards：

It is also used in the production of PVC cabinet boards and advertising boards, where it enhances the material’s processability and final appearance. For cabinet boards, it supports moisture resistance and structural integrity; for advertising boards, it delivers a smooth, uniform surface ideal for printing and branding.

3.Promote PVC Plasticization：

By effectively promoting PVC plasticization, our foaming regulator precisely adjusts the size and distribution of foam holes, optimizing the material’s density and insulation properties. This control is critical for achieving the desired performance characteristics in foam-based products.

4.Improve the Flowability of PVC Melt：

Additionally, it significantly improves the surface glossiness and overall quality of the boards, reducing defects and ensuring a premium finish. This enhancement elevates the aesthetic appeal and market competitiveness of the final products, meeting the stringent standards of the PVC industry.
