1. Significantly improve melt strength
By enhancing the cohesion of PVC melt, effectively encapsulating foaming gas, preventing bubble coalescence or rupture, ensuring stable and evenly distributed cell structure.
The network structure formed by high molecular weight characteristics (usually>3 million) greatly improves the tensile resistance of the melt, reduces the risk of gas escape and bubble collapse.
2. Optimize the pore structure and uniformity
Regulate the viscoelasticity of the melt to maintain stable morphology of the bubbles during expansion, avoiding adjacent bubbles from being crushed due to insufficient melt strength.
Forming a small and dense closed cell structure (pore size can be controlled within 80-150 μ m), reducing the density of the product while improving its mechanical strength.
3. Improve processing performance
Promote plasticization: Accelerate the melting plasticization process of PVC resin, improve plasticization uniformity and efficiency, and shorten the production cycle.
Adjusting fluidity: balancing molecular chain activity, reducing frictional resistance, ensuring moderate melt fluidity, and avoiding processing of overheated coke.
Enhance process adaptability: Compatible with high filling formulas (such as high calcium powder addition), suitable for different process requirements such as free foaming and skin foaming.
4. Improve product quality
Surface smoothness: Promote the dispersion of additives, eliminate surface defects, make the surface of foam boards/pipes smooth and delicate, and facilitate subsequent printing or veneering.
Dimensional stability: Optimize internal stress distribution, reduce deformation caused by temperature or external forces, improve product accuracy and durability.
Lightweight and High Strength: Achieving a balance between low density (up to 0.6g/cm ³) and high strength, while also considering sound and heat insulation performance.
5. Widely applicable and environmentally compatible
Suitable for various fields such as building partitions, furniture profiles, shoe materials, pipes, etc., meeting the needs of lightweight building materials and high-end consumer goods.
Coordinated with environmentally friendly additives such as calcium and zinc stabilizers, it complies with international standards such as REACH/ROHS and is suitable for food contact grade products.
