PVC WPC Door Panel and Door Frame Specialized Foaming Regulator K200

Product Principle：
When incorporated into PVC/WPC formulations, K200 functions as a multifunctional PVC processing additive that accelerates gelation of PVC particles while improving wood fiber dispersion. Under heat and shear during extrusion, it promotes melt homogeneity by increasing cohesion between polymer chains and fillers. The enhanced melt strength effectively encapsulates expanding gas from blowing agents, creating stable microcellular structures. For WPC applications, this prevents cell collapse around wood particles, ensuring uniform density throughout door profiles.

Performance Characteristics:
This specialized PVC processing additive demonstrates exceptional low-temperature plasticization promotion, enabling energy-efficient processing of WPC compounds. It significantly enhances melt strength and elongation at break, essential for maintaining foam integrity during complex door frame extrusion. The additive exhibits superior dispersibility in highly filled PVC/wood composites, ensuring consistent foam cell distribution. Additionally, K200 reduces melt fracture and die swell, enabling precise dimensional control of door profiles.

Usage and Dosage：
Recommended addition level is 5%–11% based on total formulation weight, depending on wood fiber content, desired foam density, and extrusion conditions.

1. Specialized Design for WPC Door Applications：
Unlike general-purpose foaming regulators, K200 is molecularly engineered for PVC/WPC door panel and frame production. Its optimized rheological properties ensure excellent compatibility with wood fibers, preventing agglomeration and promoting uniform dispersion.

2. Superior Plasticization at Low Temperatures：
As an advanced PVC processing additive, K200 accelerates fusion of PVC in highly filled WPC compounds. This low-temperature activation reduces thermal degradation risks for wood components while lowering energy consumption.

3. Enhanced Melt Strength for Complex Profiles：
K200 dramatically improves melt strength and elasticity, critical for maintaining foam structure during extrusion of complex door frame geometries. The enhanced melt tension prevents cell coalescence, ensuring uniform density distribution even in thin-walled sections.

4. Optimized Foam Structure and Surface Quality：
By stabilizing bubble formation, this regulator facilitates fine, closed-cell structures that maximize mechanical strength while minimizing weight. Its excellent dispersibility results in smooth, glossy surfaces free from defects, eliminating secondary finishing operations.

5. Processing Stability for Continuous Production：
K200 reduces melt pulsation and die build-up during extended runs, ensuring consistent quality and minimizing downtime—particularly valuable for continuous door profile extrusion.

1.PVC/WPC Door Panels:
K200 is specifically formulated for solid and foam-core WPC door panels. It ensures uniform cell structure throughout panel thickness, providing excellent thermal insulation, sound dampening, and dimensional stability. Enhanced surface quality allows direct painting or lamination.

2.PVC/WPC Door Frames:
For complex door frame profiles requiring precise dimensional control, K200 delivers exceptional processing stability. Improved melt flow ensures complete filling of intricate mold geometries while maintaining consistent foam density.

3.PVC Construction Boards and Foam Boards:
Beyond door applications, K200 is suitable for PVC construction boards where enhanced foam structure and surface quality are required, making it ideal for applications demanding both aesthetic appeal and structural integrity.

4.Promoting PVC Plasticization in Filled Systems：
In highly filled WPC formulations, K200 effectively promotes PVC plasticization while ensuring uniform distribution of wood fibers, resulting in improved mechanical properties and reduced water absorption.
