Uses for HFA Derivatives
| |
|
Hexafluoroisobutylene
(HFIB) |
Hexafluroisobutylene is a specialty monomer used in coatings and fluoropolymers, to produce materials with high temperature and chemical stability and good optical properties. In addition, HFIB can be used for blowing agents and refrigerants, and for specialty chemical applications. |
Hexafluoroisopropanol
(HFIP) |
HFIP is a used as an intermediate for pharmaceuticals and agrochemicals, and as a solvent or cleaner in electronics. In addition, HFIP finds use in analytical applications due to its ability to dissolve a variety of polymers including polyesters, polyamides, polyacrylonitriles, polyacetals, and hydrolyzed polyvinyl esters.
HFIP is a volatile and polar material, with high density, low viscosity and low surface tension. It is transparent to UV light (<2000 A), and has a low refractive index.

| 6-FTA |
6-FTA is useful as a chemical intermediate or monomer in fluorinated resins in markets including electronics and aerospace. |
| 6-FDA |
6-FDA is specialty monomer used in polyimides and performance resins, for markets including electronics and aerospace. |
| Allyl HFIP |
Allyl HFIP is a new product from DuPont, used in specialty polymers. |
| Bis-o-Xylene AF |
Bis-o-xylene AF is useful as a chemical intermediate or monomer in fluorinated specialty chemicals and polymers. |
Custom Manufactured
Products |
These fluorinated specialty products are valued for their high temperature stability, low refractive index, strong solvency and chemical resistance. They are used as monomers for polyimides and fluoroelastomers, as curing agents in performance polymers and as specialty solvents. Markets include electronics, aerospace, pharmaceuticals, and other uses demanding high temperature stability, chemical resistance, and excellent UV stability. |
