25067-11-2 Usage
Chemical Properties
Similar to polytetrafluoroethylene but has a higher coefficient of friction.
Uses
Perfluoroethylene propylene copolymer can be used in wire and cable insulation, pipe linings, lining for processing equipment. Fibers are used for filtration screening and mist separators.
Definition
A copolymer of tetrafluoroethylene and hexafluoropropylene with properties similar to polytetrafluoroethylene resin. The repeating structure of the molecule is [–CF2–CF2–CF2CF(CF3)–]n.
Production Methods
The elastomer is prepared by high-pressure, free-radical
aqueous emulsion polymerization. Fluorine is substituted
for hydrogen. The initiators are organic or inorganic peroxy
compounds, such as ammonium persulfate, and the emulsifying
agent is usually a fluorinated acid soap. Applications
include tubing, hose, and gaskets.
Check Digit Verification of cas no
The CAS Registry Mumber 25067-11-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,0,6 and 7 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 25067-11:
(7*2)+(6*5)+(5*0)+(4*6)+(3*7)+(2*1)+(1*1)=92
92 % 10 = 2
So 25067-11-2 is a valid CAS Registry Number.
