Wet End Starch
Our Wet End Starch is developed to address common issues such as fiber retention and filler distribution directly at the wet end of papermaking. It seamlessly integrates into the paper pulp, improving tear resistance and overall sheet uniformity while streamlining drainage and dewatering processes. This starch is an excellent option for manufacturers keen on optimizing production processes and achieving sustainable, low-energy operations.

产品特点
1. Low gelatinization temperature, high transparency and stability of paste, weak coagulation, and not easy to stratify.
2. High dispersibility and solubility, with positively charged groups, good adhesion to fibers.
3. Strong affinity for negatively charged fibers and fillers, used for paper pulp addition, with obvious enhancement, retention and filtration effects.
4. Low protein content, paste is not easy to corrupt, no foam, no odor.
