Zexin Black Silicone Color Masterbatch for Consistent Black Coloration in Silicone Products

This silicone color masterbatch is a high-performance colorant developed for silicone coloring. Its core advantage lies in excellent dispersion and stable finished appearance. We carry out sample tests under your actual compounding conditions to check color spots, color difference and flow marks. All compounding conditions and addition ratios can be well recorded. After sample preparation, we observe the finished appearance and give test feedback, helping you effectively avoid common surface defects of silicone products. It has good compatibility with various silicone materials and will not interfere with the normal vulcanization of silicone. It fits multiple processing methods including compression molding, extrusion and calendering. Standard products comply with RoHS and REACH. Food-grade versions meeting FDA and LFGB requirements are available upon request. Actual performance is affected by silicone formulation, addition ratio and processing conditions. Product images are for illustration only. The final product shall prevail.
