FLUORINE-CONTAINING COPOLYMER - A simplified explanation of the abstract
This abstract first appeared for US patent application 18452075 titled 'FLUORINE-CONTAINING COPOLYMER
Simplified Explanation
The patent application describes a copolymer that contains tetrafluoroethylene, hexafluoropropylene, and perfluoro(propyl vinyl ether) units. The copolymer has specific mass percentages of hexafluoropropylene and perfluoro(propyl vinyl ether) units, a specific melt flow rate, and a specific number of —CFH groups per 10 main-chain carbon atoms.
- The copolymer contains tetrafluoroethylene, hexafluoropropylene, and perfluoro(propyl vinyl ether) units.
- The copolymer has a mass percentage of hexafluoropropylene units between 9.5% and 12.2%.
- The copolymer has a mass percentage of perfluoro(propyl vinyl ether) units between 0.5% and 1.4%.
- The copolymer has a melt flow rate at 372°C between 0.8 and 4.0 g/10 min.
- The copolymer has a number of —CFH groups of more than 50 per 10 main-chain carbon atoms.
Potential applications of this technology:
- Coating materials for various surfaces, such as metals, ceramics, and plastics.
- Insulation materials for electrical wires and cables.
