Suspension Low Viscosity PVC Paste Resin 9002-86-2 Langhui LF-51L
1. Product Introduction
LF-51L is a high-performance PVC paste resin with stable quality and excellent processing properties. It features low paste viscosity, small viscosity change over time, good defoaming performance, uniform foaming micropores, strong thermal stability and fast gelation. With a moderate average polymerization degree and optimized particle size distribution, it is easy to mix, disperse and process, which can effectively reduce defects such as bubbles and pinholes, and ensure smooth surface and stable quality of finished products. It is widely used in soft PVC products requiring good foaming, coating and molding performance, and has high adaptability to various production lines and formula systems.
