Proprietary Chemical Technology Solutions | SL-TECH

Changzhou Sanli Tech International Trade Co., Ltd. is built upon a foundation of proprietary chemical technology, representing the culmination of years of dedicated research, development, and practical application. Our portfolio encompasses over 172 complete sets of chemical technology, many of which are unique to our company, providing clients with a distinct competitive advantage. We have developed specialized processes for key industries, such as our advanced Formaldehyde (Fe-molybdenum Method) Plant, which delivers high conversion rates and minimizes by-product formation, setting a new standard for efficiency. For the production of high-value polymers, our proprietary technology for the Polysulfone Plant ensures consistent, high-molecular-weight polymer production with superior thermal and mechanical properties. This technology, developed in collaboration with our R&D centers in Tianjin, Qingdao, and Shanxi, incorporates advanced purification steps to achieve the high purity required for critical applications like membrane filtration and medical devices. Our proprietary approach extends to the entire process, from the initial catalyst preparation to the final product handling. For a client seeking to enter the DMMn (Polyoxymethylene Dimethylether) market as a clean diesel additive, our proprietary technology offers a highly selective route that maximizes yield and minimizes by-products, ensuring the final product meets the most stringent fuel specifications. By choosing our proprietary chemical technology, clients gain access to proven, optimized processes that are not readily available elsewhere, providing a strong barrier to entry for competitors.
