PVC High Foaming Profiles Special High Viscosity Foaming Regulator K530

Product Principle：
When incorporated into PVC formulations for high-foam profiles, K530 acts as a powerful rheology modifier accelerating gelation and fusion under heat and shear. Its high molecular weight structure enhances melt cohesion and viscoelasticity, effectively encapsulating expanding gas bubbles from blowing agents. The increased melt tension prevents bubble coalescence and rupture, promoting uniform fine-celled foam structures critical for high-expansion applications where conventional limits are exceeded.

Performance Characteristics:
This advanced PVC processing additive exhibits outstanding low-temperature plasticization promotion, enabling energy-efficient processing in high-output extrusion lines. The elevated intrinsic viscosity imparts superior melt strength and elasticity, allowing foam densities below 0.3 g/cm³ without sacrificing rigidity. K530 demonstrates excellent dispersibility, ensuring uniform foam cell distribution with low volatile content (≤1%) for stable extrusion operations. It reduces melt fracture and die swell, resulting in precise dimensional control and smooth, glossy surfaces.

Usage and Dosage：
Recommended addition level is 3%–8% based on total formulation weight, depending on target foam density, profile geometry, and extrusion conditions. Preliminary trials advised for optimal performance.

1. High Viscosity for Exceptional Melt Strength：
With intrinsic viscosity of 14.0–14.5, K530 provides superior melt strength essential for stabilizing high-expansion-ratio foam structures, preventing cell collapse and enabling consistent ultra-low-density profile production.

2. Efficient Plasticization Promotion：
As a high-performance PVC processing additive, K530 significantly accelerates PVC fusion, reducing processing temperatures and energy consumption while improving throughput rates.

3. Uniform Microcellular Foam Structure：
Enhanced melt tension ensures uniform bubble expansion and stability throughout extrusion, creating fine closed-cell structures that maximize mechanical properties and thermal insulation.

4. Superior Surface Quality and Dimensional Stability：
Excellent dispersibility and flow enhancement yield smooth, glossy surfaces free from defects. Improved melt flow reduces die swell and warpage, ensuring precise profile dimensions.

5. Processing Stability for High-Output Extrusion：
K530 minimizes melt pulsation and die build-up during continuous runs, enhancing process stability and reducing downtime for large-scale manufacturing.

6. Broad Formulation Compatibility：
Compatible with various PVC formulations including those with fillers, impact modifiers, and other additives, making it versatile for different high-foam applications.

1.PVC High-Foam Profiles:
K530 is specifically designed for high-foam PVC profiles such as window and door frames, decorative moldings, and architectural trims, enabling foam densities as low as 0.3 g/cm³ while maintaining excellent mechanical strength and surface aesthetics.

2.PVC Foam Boards and Sheets:
Suitable for manufacturing PVC foam boards including free-foam and Celuka-type boards, where uniform cell structure and smooth surfaces are required for signage, furniture, and construction panels.

3.Complex Extrusion Applications：
In profiles with intricate cross-sections, K530 ensures complete uniform plasticization, allowing melt to fill complex die geometries without compromising foam quality or dimensional accuracy.

4.Enhancing Surface Finish：
By improving rheological properties, K530 facilitates smoother extrusion and superior surface finish, reducing post-processing needs and enhancing aesthetic appeal.
