Hangzhou Aotong Chemical Co., Ltd

       Hangzhou Aotong Chemical Co., Ltd. was established in 2007 and is a new technology enterprise specializing in the research and sales of papermaking chemicals. The company's main products include liquid water retaining agents, thickeners, rheology agents, bio based dispersants, lubricants, water resistance agents and other core products. With 18 years of deep cultivation in the paper industry, the company has served over 50 paper companies, helping customers achieve process upgrades and cost reduction and efficiency improvement, and promoting the upgrading and replacement of traditional chemicals.

     The thickening efficiency is better than CMC, which can achieve the required viscosity level of the coating at a very low dosage and is suitable for coating machines at various speeds.

       Helps to use a full calcium carbonate formula for coatings, reducing costs. Control high shear viscosity and reduce scraper loading. Higher coating solid content and better operability. Enhance the suspension stability of coatings, reduce sedimentation and delamination, prolong the use time of coatings, and reduce customer downtime losses.

       The world's leading new quality technology, different from traditional polyacrylic acid dispersants, can increase the solid content of biomass raw material dispersants to 50%, with a dosage of 70-50% of traditional dispersants. It has lower product viscosity at low temperatures, reduces coating flocculation, prevents sedimentation, and makes coatings more stable. Biomass based raw materials can reduce COD and make the environment more friendly.

       Cationic modified natural polymers have the characteristics of high cation density and active groups that can be crosslinked on the molecular chain. Through the action of positive and negative charges, it can adsorb well on the surface of fibers, and under the action of heat, it can undergo cross-linking reaction with hydroxyl groups on the surface of fibers, thereby improving the interlayer bonding of cardboard/paper. This product can neutralize anionic waste in the system and improve the retention rate of fine fibers.

Product performance advantages

        Revolutionary replacement of traditional CMC, with higher cost-effectiveness and process adaptability, can improve the water retention rate of coatings, reduce the risk of coating agglomeration, enhance the glossiness and smoothness of paper, reduce usage, and lower overall costs.

One of the earliest domestic manufacturers to provide thickeners, water retaining agents, rheology agents, and biomass based dispersants
The product has passed GB9685, FDA, and BfR certifications, and its performance is benchmarked against international brands
