Nagase & Co., Ltd., in conjunction with group company Nagase ChemteX, is working to expand market for its Denafilter,
a polymer filter used in film extrusion and other applications.
In addition to broaden the product range to meet a much diversified demand, emphasis will be placed on recycling used filters
in view with the increasing level of environmental awareness. The company is planning an annual growth of 2 billion yen for the Denafilter business.
Polymer filters remove impurities and gel from polymer solutions
including PET, PP, PC, cellulose and poval. Filters are needed
in wide variety of sizes and shapes from the circular leaf
disk filter to the bar-shaped candle bar filter, and Nagase
is enhancing its product range to meet this diverse demand.
Nagase's polymer filter is made of heat-and-pressure-resistance,
anti-corrosive stainless steel, featuring a special inner
retainer. Normally when filtration levels are increased, there
is greater resistance and risk of clogging, but Nagase's patented
Denafilter effectively widens the filtration area and can
be used for high viscosity polymers that are proven impossible
for conventional filters. Learn more about Denafilter
The filter is already in use not only in Japan, but also
Europe, the USA and Asia including China, Korea and Taiwan.
Nagase is targeting in particular the China and Southeast
Asia markets which are seeing an influx of large numbers of
foreign enterprises, and the filter will be aggressively marketed
along with Nagase's other leading products such as plastics
and monomers.
Nagase will also be emphasizing its recycling service of
used filters in cooperation with Nagase ChemteX. Nagase ChemteX's
Harima Works in Tatsuno City, Hyogo Prefecture, is equipped
with facilities for industrial waste burning, chemical cleaning
and ultrasonic cleaning, offering optimal cleaning method
for any type of filters.
Currently the company has contracted with 30 to 40 companies,
and expects rapid expansion with the increasing demand for
its service due to environmental awareness of filter users.
