SM3 / SM5 Matte Grade PVC Resin
Certificate of Analysis
1. Product Introduction
SM3 and SM5 are special suspension matte PVC resins designed for delustered finished goods. With controlled cross-linked gel content, they deliver stable matte surface effect without extra matting powder addition. Featuring high plasticizer absorption, low fish-eye count, low residual VCM and excellent processing stability, they are widely used for matte artificial leather, matte flooring, matte calendared films and low-gloss PVC profiles.
