Choose the Right Additives for High-Quality Foamed Products
Abstract: In recent years, PVC foamed products such as PVC wall panels, grilles and door panels have been widely used in interior projects including residential decoration, hotels and apartments, thanks to their waterproof, moisture-proof, durable and eco-friendly features. Premium resin is the foundation. Combined with tailor-made additive formula from MAIJISEN, the full performance of PVC foamed articles can be maximized. This article introduces how MAIJISEN functional additives empower PVC foamed boards to produce stable and high-quality finished goods.
1.Waterproof & Moisture-proof, Low Water Absorption & Swelling
PVC foaming is a high-temperature extrusion process. PVC resin tends to thermal degradation, material sticking and discoloration during processing.
Calcium zinc heat stabilizer controls temperature throughout extrusion, restrains thermal decomposition of PVC resin and ensures continuous stable production. It helps finished products maintain good waterproof & moisture-proof performance and reduce swelling caused by water absorption.
2. Dimensional Stability, Anti-deformation & Anti-cracking
Boards feature low warpage, low shrinkage and excellent crack resistance with consistent dimension, which simplifies installation and delivers better appearance.
1.Lightweight & Uniform Cell Structure
AC/NC foaming agent releases gas steadily. Together with foaming regulator to precisely control melt strength, fine and uniform foam cells are formed. It realizes lightweight finished products, cuts raw material cost and keeps full & smooth board surface.
2. Improved Strength & Flexibility
Toughness-enhancing modifier greatly improves impact resistance and flexibility, solving the brittleness weakness of PVC foamed sheets. Final boards are impact-resistant and bend-resistant. No cracking during cutting, assembly and transportation.
3.Smooth Board Surface & Stable Molding
Internal & external lubricant optimizes melt fluidity and reduces friction during extrusion. Smooth extrusion process delivers glossy and uniform board surface, compatible with lamination, heat transfer printing, spraying and other post-processing.
4. Higher Processing Efficiency & Eco-friendly
Maijisen supplies complete additive packages customized for different formulations and application scenarios to compensate material performance defects. Processing modifiers optimize melt rheology for high-speed extrusion, reduce production fluctuation. Product quality is improved while meeting relevant environmental standards.
The outstanding performance of PVC foamed products cannot be achieved by PVC resin alone. It relies on the synergy of various functional additives. Ca/Zn stabilizers, lubricants, impact modifiers, foaming agents, foaming regulators and processing aids work together to overcome inherent drawbacks of WPC/PVC foaming materials. We help manufacturers mass-produce high-quality PVC foamed products with fewer defects.
