Product Introduction：

1. Product Overview：
K530 is a high-performance PVC foaming regulator specifically designed for both extrusion and injection foaming processes. As a methyl acrylate-based polymeric additive, it is particularly suitable for production lines equipped with new screws featuring excellent plasticizing capacity. K530 is optimized for foamed products with thicknesses ranging from 5 mm to 40 mm, and it excels in high plasticizing speed and low-density applications. It promotes uniform plasticization, enhances melt strength, and improves foam structure, making it an ideal choice for manufacturers seeking consistent quality in demanding foaming operations.

2. Product Principle：
K530 functions as a high-molecular-weight acrylic copolymer that interpenetrates and entangles with PVC molecular chains during processing. This interaction significantly enhances melt cohesion and homogeneity while increasing melt strength, elongation, and elasticity. By improving the rheological properties of the PVC melt, K530 stabilizes the foaming process—it reinforces cell walls during bubble expansion, preventing cell coalescence or collapse, and promotes the formation of a uniform, fine-cell structure. The result is a low-density foam (≥0.3 g/cm³) with excellent mechanical integrity and dimensional stability, even in thick sections.

3. Performance Characteristics：
K530 delivers outstanding processing performance with a plasticizing time of just 29 seconds, enabling rapid fusion and early melt homogenization. The torque values (min. 10.3 NM, max. 53.7 NM, balanced 24.9) indicate excellent processing stability and reduced melt pulsation. The high viscosity and balanced torque ensure superior melt strength and elasticity, preventing cell rupture and ensuring uniform foam structure. The low volatile content guarantees clean processing with minimal emissions, while the methyl acrylate composition provides excellent compatibility with PVC resins and other processing additives. K530 is particularly effective in thick foamed products where uniform cell structure and surface quality are critical.

4. Usage and Dosage：
Recommended addition level is 3–5% based on total PVC formulation weight. For standard extrusion and injection foaming applications with thicknesses between 5 mm and 40 mm, dosages of 3.5–4.5% typically provide optimal results. For high plasticizing speed lines or low-density products, dosages toward 5% are recommended. Systematic trials should be conducted to fine-tune the dosage for specific equipment, screw configurations, and target foam density requirements.

Product Advantages:

1. Promotes Low-Temperature Melting and Uniform Plasticization
K530 accelerates PVC fusion under lower processing temperatures, enabling energy savings and reduced thermal stress on the material. It ensures homogeneous plasticization throughout the melt, eliminating unmelted particles and improving overall product consistency.

2. Strengthens Melt Cohesion and Homogeneity
By increasing melt cohesion and molecular entanglement, K530 improves the uniformity of the PVC melt. This reduces melt pulsation and instability, ensuring consistent extrusion and injection performance with excellent dimensional accuracy.

3. Enhances Melt Strength, Elongation, and Elasticity
K530 significantly improves melt strength, elongation, and elasticity, enabling the melt to withstand the extensional forces during foaming. This prevents cell wall rupture and coalescence, producing a fine, uniform cell structure with excellent mechanical properties.

4. Reduces Melt Pulsation and Processing Instability
The improved rheological properties provided by K530 minimize melt pulsation and flow instability, resulting in smooth, consistent processing. This translates into higher line speeds, reduced scrap rates, and more reliable production.

5. Promotes Smooth Surface and High Gloss
With excellent dispersibility in PVC formulations, K530 ensures a smooth, glossy surface finish free from defects such as roughness, die lines, or orange peel. This enhances the aesthetic appeal of foam boards, profiles, and injection-molded parts.

6. Excellent Dispersibility and Compatibility
K530 disperses readily in PVC compounds, ensuring uniform distribution throughout the melt. Its excellent compatibility with PVC resins, stabilizers, lubricants, and foaming agents simplifies formulation development and ensures consistent product quality.

7. Tailored for Thick Foamed Products (5–40 mm)
K530 is specifically engineered for thick-section foaming, where uniform cell structure and dimensional stability are challenging. It maintains melt strength throughout the expansion process, preventing sagging or collapse in thick foamed boards and profiles.

8. Suitable for High Plasticizing Speed and Low-Density Applications
K530 performs exceptionally well in high-speed production lines and low-density foam applications. It enables significant weight reduction while maintaining structural integrity, making it ideal for lightweight furniture boards, construction panels, and automotive components.
