Perfluoropolyether, abbreviated as PFPE, is a non-toxic and non-flammable special polymer compound. It is a colourless transparent liquid at room temperature. Since the molecular structure of PFPE contains C, F and O, and does not contain any carbon-hydrogen bonding, which makes it have extremely high thermal and chemical stability. Our perfluoropolyether products include lubricants, heat transfer fluids, vapor phase soldering fluids and immersion coolants.

The refrigeration oil serves as a hydraulic control, functional fluid and lubricating oil in refrigeration compressors under the influence of the refrigerant.It plays four roles: lubrication, sealing, cooling and energy regulation.

Pressure vessels are leak-proof containers that store liquid or gas.Pressure vessels of various sizes and shapes have been produced for different purposes. Generally,preferred geometries are spherical,conical,and cylindrical.A typical model is the combination of a long cylinder with two heads.Pressure vessels work at internal pressures higher or lower than air pressure.Besides,the operating temperatures of these systems differentiate.

There are many categories of specialty gases, which can usually be divided into electronic gases, standard gases, environmental protection gases, medical gases, welding gases, sterilization gases, etc. They are widely used in electronics, electricity, petrochemicals, mining, steel, non-ferrous metal smelting, thermal engineering, biochemistry, environmental monitoring, medical research and diagnosis, food preservation and other fields.
