Guangyuan supplies a range of organofluorine intermediates and fine chemicals used in fluoropolymer synthesis, electronics etching, refrigeration and solvents. These are hazardous chemicals, traded under licence in accordance with national regulations and supplied with MSDS and required safety labelling.
Technical Parameters
Note: the parameters above are typical values for the standard grades of each series and are for selection reference only; actual specifications follow the official TDS for the selected grade and the agreed contract.
Hexafluoropropylene (HFP)
One of the basic raw materials of the organofluorine industry — a key monomer for many fluorinated copolymers and an intermediate for numerous fluorinated compounds. Formula C3F6, CAS 116-15-4.
| Property | Nominal value |
|---|---|
| HFP w/% ≥ | 99.98 (top grade) / 99.90 (first grade) |
| Organic impurities w/% ≤ | 0.02 / 0.10 |
| Oxygen % ≤ | 0.005 |
| Water w/% ≤ | 0.004 / 0.006 |
| Melting point °C | -156.2 |
| Boiling point °C | -29.4 |
| Relative density (water=1) | 1.58 |
| Packing | Cylinder or tank car, filling ratio 1.06 kg/L |
Octafluorocyclobutane (C-318)
Used as a spray agent in the food industry, refrigerant and integrated-circuit etchant; can be blended with SF6 as a dielectric. Formula C4F8, CAS 115-25-3.
| Property | Nominal value |
|---|---|
| C-318 w/% ≥ | 99.99 (top grade) / 99.95 (first grade) |
| Water w/% ≤ | 0.001 / 0.002 |

| Melting point °C | -41.4 |
| Liquid density (25°C) | 1.62 g/cm³ |
| Packing | Cylinder, filling ratio 1.296 kg/L |
Tetrafluoropropanol (TFP)
Good solvency for many organic substances; widely used as a dye solvent in CD-ROM and DVD-R optical media production. Formula C3H4F4O, CAS 76-37-9.
| Property | Nominal value |
|---|---|
| TFP w/% ≥ | 99.95 (top grade) / 99.90 (first grade) |
| pH | 5–8 |
| Water w/% ≤ | 0.015 / 0.020 |
| F⁻ mg/L ≤ | 1.0 |
| Boiling point °C | 107–109 |

Applications
- Monomers for fluoropolymers and elastomers
- Electronics and semiconductor etching gases
- Refrigerants and food-industry spray agents
- Optical-media dye solvent and fluorinated intermediates
Packaging & Storage
HFP/C-318: cylinder or tank car; TFP: dedicated 200 L steel drum. Supplied with MSDS and safety labelling.
Hazardous chemicals — trading under licence required. Elevated C-318 concentration can reduce ambient oxygen below 19.5%, causing asphyxiation; contact causes frostbite. TFP decomposes into toxic matter in fire and is irritating. Store and transport in a cool, well-ventilated, dry place away from heat and direct sunlight; self-contained breathing apparatus is required for responders.
