Fluorinated ethylene propylene FEP
Synthesis: using emulsion polymerization, the polymerization processes
often use the initiator is water soluble inorganic peroxides such as money
or Persulfate potassium persulfate, inorganic peroxide system represents
the persulfate initiated polymerization to generate FEP
Properties: FEP crystalline melting point 304 °C, density is 2.15, it is a kind of soft plastic, tensile strength, abrasion
resistance, creep resistance is lower than that of many engineering
plastics.It is chemically inert, in a very wide temperature and frequency
range has a low dielectric constant (2.1).This material can prevent the
ignition, flame spread, excellent weatherability, low coefficient of friction,
from low temperature to 200 "C can be used.The material can be made
for extruded and molded granular product, used as a bed and electrostatic
coating powder, can also be made into an aqueous dispersion.
Usage: FEP has excellent corrosion resistance, is currently the most deal anti corrosion materials.FEP lining ball valves for petroleum, chemical, dye,
pesticide and other industries in the various strong corrosive medium,
open and close control and development.FEP lining ball valve shell
casting with casting, smooth appearance, high strength, contact with
the corrosive medium with FEP lining bag, products in various acid,
alkali, salt corrosive medium using.Its main purpose is the production
of pipe and chemical equipment, cylinder liner surface layer and a
variety of wire and cable, such as aircraft hook line, booster cable,
alarm cable, flat cable and oil well logging cable.
