Product Description
Chemical Name: Heptafluoropropyl methyl ether, Perfluoropropyl methyl ether
Common Name: Methyl perfluoropropyl ether, Heptafluoro-1-methoxypropane
CAS No: 375-03-1
Chemical Structure:
Heptafluoropropyl methyl ether (CAS 375-03-1), also known as Perfluoropropyl methyl ether, commercialized as TPD-HFE-7000, is a high-purity colorless transparent hydrofluoroether fluid and a mature and reliable 3M Novec 7000 replacement product.
This material boasts zero ozone depletion potential (ODP), relatively low global warming potential (GWP) and an ultra-short atmospheric lifetime of only 4.9 years, fully complying with global environmental protection regulations and serving as a premium alternative to traditional ozone-depleting substances (ODS). It delivers outstanding chemical and thermal stability, low toxicity and excellent non-corrosive properties. Even if accidental leakage occurs during operation, it will not damage precision electronic devices and industrial equipment. With low surface tension, low viscosity and complete residue-free evaporation, it is specially developed for various low-temperature working scenarios and has become a mainstream low-temperature heat conduction medium across multiple industries.
Key Features
- Premium Environmental Performance: ODP = 0 (no ozone layer damage), GWP = 420, short atmospheric lifetime (4.9 years), eco-friendly and compliant with international environmental policies.
- Excellent Safety & Stability: Low toxicity, non-flammable with no flash point; superior chemical inertia and thermal stability, resisting decomposition under conventional working temperatures.
- Superior Physical Properties: High density, low kinematic viscosity and low surface tension; evaporates completely without leaving any residue on component surfaces.
- Non-Corrosive Characteristic: No corrosion to metals, plastics and other common industrial materials. Leakage will not cause damage to precision electronic equipment.
- Low-Temperature Adaptability: Outstanding performance under ultra-low temperature conditions, stable fluidity and heat transfer efficiency for long-term low-temperature operation.

Safety Operation Guidelines:
1. TPD-HFE-7000 (Heptafluoropropyl methyl ether, CAS 375-03-1) is a volatile liquid. It will decompose when exposed to high temperature, producing toxic hydrogen fluoride and fluorocarbon organic compounds. Strictly keep away from high-temperature environments, heat sources and fire sources.
2. During operation, avoid liquid splashing into eyes and direct skin contact. Wear protective gloves, gas masks and safety goggles as standard protective equipment.
3. Seal the container tightly immediately after use to prevent product volatilization and quality loss. Wash hands thoroughly after finishing all operating procedures.
4. Conduct all operations in a well-ventilated workshop to reduce the concentration of volatile gas in the air.
Packing
Available in N.W.5KG Plastic drums, N.W.25KG or N.W.250KG Iron drums.
Transportation & Storage
1. Transported as a non dangerous chemical.
2. Should be stored in a clean, dry warehouse, protecting from high temperature insolation.
3. Kept away from heat sources, away from acids, strong alkalis, oxidants, etc.
4. Avoid violent vibration during transportation and avoiding upside-down when stacking.
5. Pay attention to the tightness of the product during storage and transportation.
