Perfluoropolyether (PFPE) belongs to the
family of fluorinated synthetic fluids. PFPE are low-molecular-weight,
partially fluorinated, oxetane oligomeric polyols that are non-toxic,
non-flammable, and resistant to chemicals. They are used in extreme
temperatures varying from −80°C to 200°C. PFPE are polymeric
species having repeated per fluorinated methyl-, and ethyl- or isopropyl ether
units. They have a variety of application-specific end groups. Depending on the
application, their molecular structure varies from linear, branched, to a
combination of both. They are synthesized by photo-initiated oxidative
polymerization. There exist four different kinds of PFPE fluids viz. PFPE-K,
PFPE-M, PFPE-Y, and PFPE-Z. All PFPE fluids contain oxygen, carbon, and
fluorine atoms. However, each type of fluid is a product of different starting
materials and manufacturing processes. These structural differences affect the
temperature resistivity, ability to prevent wear, lubricity, and volatility of
the fluid.
Based on the end-user application, the market for PFPE has been
segmented into automotive, electronics, aerospace, and coatings. Demand for
non-toxic, non-flammable, corrosion-resistant specifications of lubricants,
growth in the automotive industry, increasing defense budgets, and growing technology
in the aerospace industry are the factors driving the PFPE market. PFPE is used
significantly in the aerospace industry as instrument-bearing grease,
joint-bearing grease in aircraft fuel systems and astronaut spacesuit bearings.
Additionally, it is used extensively for coating the surfaces of tiles, stones,
ceramics, and glass for imparting the properties such as oil and water
repellency and low adhesion and friction.

PFPE is also employed in the electronics industry, as it is used
as a vacuum grease in semiconductor processing and as a top-coating lubricant
in CD drives. In the automotive industry it is utilized for coating in advanced
braking system (ABS) and as a grease between gears. However, lack of literature
and R&D, diminishing market for CD drives, and emission of fumes from the
PFPE fluid upon contact with high temperatures are the factors likely to hamper
the market for PFPE. Opportunities to bridge the gap by providing literature
regarding environmental aspects of PFPE fluids exist for the companies.
In terms of region, the global perfluoropolyether market has
been segmented into Asia Pacific, Middle East & Africa, Europe, North
America, and Latin America. The aerospace industry in North America is
projected to hold a dominant share of the market for PFPE during the forecast
period. The market in North America is anticipated to expand during the
forecast period, due to the large-sized aerospace industry in the U.S., and its
high defense budgets,. The PFPE market in Europe is also anticipated to witness
growth due to extensive research and development activities in the aerospace
industry in France and Germany.
The PFPE market in Asia Pacific is projected to witness rapid
growth, due to development in infrastructure, electronics, ceramics, and
automotive sectors. The automotive industry in Asia Pacific peaked in 2015, due
to large production of vehicles and booming exports of electronic appliances
from China, Japan, and Taiwan. The U.S. holds a major share in production of
electronic appliances and is anticipated to be a potential market for PFPE in
North America.
Some of the key players operating in the PFPE market are Daikin,
Dow Corning, Kluber Lubrication, DuPont, Chemours Company, Solvay Solexis,
ICAN, M&I Materials Limited, Halocarbon Product Corporation, Saint Gobain,
Corning Inc., and ACG Group. Chemours Company is one of the leading
manufacturers of fluoroproducts. It has penetrated the PFPE market by its
product KrytoxTM, a high-performance synthetic lubricant which is non-flammable,
chemically inert, and able to retain its viscosity at elevated temperatures.
KrytoxTM is employed in gear boxes, bearings, and electric motors
for reducing friction.
