25101-45-5 Usage
Chemical Properties
Different sources of media describe the Chemical Properties of 25101-45-5 differently. You can refer to the following data:
1. ECTFE has thermal and oxidative stability up to 150–175 ° C.
It is chemically inert to a number of chemicals and solvents
and has good permeability resistance. The copolymer is
50–55% crystalline, depending on the method of preparation.
2. Chlorotrifluoroethylene-ethylene copolymers (ECTFE) contain about 50
mole % chlorotrifluoroethylene. These copolymers are generally similar to
the tetrafluoroethylene-ethylene copolymers in that they are
melt-processable and have high impact strength and good chemical resistance. The
temperature range of useful performance is from about - 80°C to 170°C.
Chlorotrifluoroethylene-ethylene copolymers find use in injection mouldings
for chemical process equipment and cable insulation.
Uses
Wire and cable insulation is the primary application
of ECTFE.
Production Methods
PCTFE is a polymer of chlorotrifluoroethylene. Copolymerization
of ethylene and chlorotrifluoroethylene is carried out
by aqueous suspension techniques, by low-temperature polymerization
initiated by oxygen-activated triethylboron in
dichlorotetrafluoroethane, and by radiation-induced polymerization.
Check Digit Verification of cas no
The CAS Registry Mumber 25101-45-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,1,0 and 1 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 25101-45:
(7*2)+(6*5)+(5*1)+(4*0)+(3*1)+(2*4)+(1*5)=65
65 % 10 = 5
So 25101-45-5 is a valid CAS Registry Number.
