Nippon Shokubai Develops Production Process of Novel Super-fast-drying Superabsorbent Polymer
OSAKA, Japan, Oct. 16, 2020 /Kyodo JBN-AsiaNet/ --

Nippon Shokubai Co., Ltd., (hereinafter "Nippon Shokubai"), headquartered in 
Osaka, Japan, has developed a novel superabsorbent polymer (SAP) with 
super-fast-drying absorption property, which could not be achieved in the past.

In the hygiene material industry, where SAPs are primarily used, demand not 
only for disposable diapers for infants but also for sanitary articles for 
adults (disposable diapers, napkins, pads for light incontinence, etc.) has 
been expanding in recent years. SAP properties required for sanitary articles 
for adults are different from those required for disposable diapers for 
infants. Specifically, the ability to quickly absorb liquid (fast-drying) and 
the ability to prevent the absorbed liquid from leaking (liquid retention) are 
particularly important. 

The SAP developed by Nippon Shokubai is super-fast-drying in comparison with 
existing products and has about three times better liquid retention property 
with a new production process. The idea of the new production process was 
derived from an experiment carried out by a researcher who happened to shift 
the viewpoint while aiming to develop a production process with improved 
efficiency. Based on the idea, the company's research, process technology, 
production, and engineering departments joined their expertise and succeeded in 
establishing a commercial production process.

Sanitary articles using this SAP is fast-drying and the surface immediately 
dries up upon absorption of liquid. Also, due to the excellent liquid retention 
property and absorbency against pressure, they securely retain the absorbed 
liquid without allowing leakage. Nippon Shokubai believes that these remarkable 
characteristics would be able to add great value to sanitary articles for 
adults, which are expected to grow further in the future.

Currently, the company is building a 15,000 t/y plant at its Himeji Plant, and 
expects to start production and sales from June 2021. Taking advantage of the 
unprecedented novel properties, it will also explore the possibility of 
creating new markets other than for sanitary articles.
