PSL 31 PVC Paste Resin Low Viscosity And Superior Foaming For Leather And Flooring
Discover the exceptional qualities of PSL-31, a polyvinyl chloride homopolymer crafted through microsuspension polymerization. This resin is engineered to be effortlessly converted into low-viscosity pastes, streamlining your production process. These pastes are renowned for their excellent storage stability, guaranteeing consistent performance and reliability from the moment of production until application. If your goal is a stable and manageable paste foundation, PSL-31 provides the perfect starting point for high-quality results.
The true advantage of PSL-31 lies in its intelligent rheological behavior, which adapts to your processing needs. At low shear rates, the paste displays pseudoplastic flow, thinning out for easy mixing and superior deaeration to minimize defects. As processing speeds increase, its behavior shifts to dilatant, providing the necessary stability during coating operations. This dynamic flow profile, combined with its outstanding foam-forming capabilities, gives you precise control over the texture and density of your final foamed products.
PSL-31 is the ideal material for a wide range of foaming applications, delivering performance where it matters most. It is exceptionally effective as the foaming layer in high-quality synthetic leathers, resilient floors, and decorative wallpapers. Beyond these core uses, it also excels in creating durable coatings for fabrics and canvas. This versatility makes it a trusted choice for manufacturers seeking to enhance the comfort, aesthetics, and durability of their coated and foamed end products.
Embrace the capabilities of PSL-31 to innovate and improve your product line. Its combination of low viscosity, easy deaeration, and controlled foaming empowers you to achieve superior quality with greater processing efficiency. Do not let material limitations hold back your designs. To see how PSL-31 can make a difference in your applications, we invite you to contact us for a technical consultation or to request a sample and experience its benefits firsthand.
