Technology-based, user value first
Solid technical background
The company relies on the Department of Polymer Science of Fudan University for its technology and has a solid foundation in polymer materials. In 2008, it became a production, education, and research base of Fudan University. In 2019, it jointly established the Humidity Control Materials Joint Research Center with Fudan Zhangjiang Research Institute, providing strong academic support for technological research and development.
Abundant patent achievements
It has been authorized more than 50 invention patents. In the past 3 years, it has obtained 5 Chinese invention patents, 5 US invention patents, and 3 Canadian invention patents related to humidity control materials, leading the technology in the field of humidity control.
Continuous innovation capability
From the initial unidirectional hygroscopic desiccant to the bidirectional precise humidity control agent, and then to the humidity management system with intelligent terminals and software systems, the products are constantly upgraded and iterated to meet the diversified needs of the market.
Excellent bidirectional humidity control function
Whether it is fiber-based or mineral-based humidity control products, they can not only absorb moisture but also release moisture, and can precisely control the humidity to a specific value, far exceeding the humidity control performance of traditional national standard products. For example, humidity control panels are "quantitative" humidity control, with a specific target humidity, and the humidity control capacity is 3-5 times higher than that of traditional diatomaceous earth or calcium silicate boards.
Significant green and environmental protection advantages
Composite material products based on plant fibers, such as fiber desiccants and fiber humidity control sheets, are degradable and recyclable, with no pollution risk, and do not contain EU-restricted hazardous substances. The carbon emissions of some products are reduced by about 300% per kilogram compared to silica gel desiccants.
Safe, reliable, and high-quality
Products have passed SGS ROHS, REACH, DMF and other multiple tests, and do not contain substances harmful to human body and environment. Fiber materials can be integrated with outer packaging to reduce direct contact with products, reducing the risk of leakage or accidental ingestion.
Application Cases
New Energy Vehicle Battery
Excessive humidity can accelerate battery corrosion, and reasonable regulation can extend lifespan and prevent thermal runaway.
Clothing Industry
Imbalance between temperature and humidity can easily cause fabric to mold or increase static electricity, and precise management can ensure production and storage quality.
Museum
Constant humidity can prevent cultural relics from cracking, rusting, or moldy, and is a key factor for long-term preservation.
