product details

BRIEF DESCRIPTION

Perfluoro(methyl vinyl ether) (PMVE) is a colorless gaseous fluorinated vinyl ether that serves as an important fluorinated comonomer. It is a key raw material for the production of specialty fluoropolymers and modified fluoropolymers. Fluoropolymers synthesized with PMVE exhibit outstanding resistance to acids, alkalis, and extreme temperatures, making them well suited for demanding applications requiring exceptional chemical stability and long-term reliability. Their molded products are widely used in sealing components for the nuclear, aerospace, chemical processing, pipeline transportation, and semiconductor industries. In addition, PMVE is an important intermediate for the synthesis of Diflubenzuron, a widely used insecticide.

APPLICATIONS

1. Fluoropolymer Synthesis: PMVE is widely used as a comonomer in the manufacture of specialty fluoroplastics and fluoroelastomers. It significantly enhances the low- and high-temperature resistance, chemical resistance, and long-term durability of fluoropolymers. These materials are extensively used in seals, linings, piping systems, and other critical components for the nuclear, aerospace, semiconductor, and chemical processing industries.

2. Agrochemical Intermediate: PMVE is an important intermediate in the production of Diflubenzuron, a benzoylurea insecticide widely used for crop protection.

3. Environmentally Friendly Insulating Gas: When blended with carbon dioxide (CO₂), PMVE can be used as an environmentally friendly insulating medium for high-voltage electrical insulation applications, providing an alternative with a lower environmental impact than conventional insulating gases.

STORAGE CONDITIONS

1. Keep away from heat, sparks, open flames, and other ignition sources.

2. Store in a cool, well-ventilated area to prevent pressure buildup.

3. Cylinders stored outdoors should be protected from direct sunlight and excessive heat, especially during hot weather.

4. Keep away from incompatible materials such as strong oxidizing agents, acids, and alkalis.

PACKAGE

1. Supplied in steel cylinders with product labels and certificates of conformity indicating the product grade, trademark, and batch number.

2. Alternative packaging options are available upon customer request.

CHEMICAL PROPERTIES

PMVE is a colorless gas at ambient temperature and pressure, with a boiling point of -23 °C. It is flammable and may form explosive mixtures with air. The product is incompatible with strong oxidizing agents, acids, and alkalis. Under dry conditions, PMVE is relatively stable; however, exposure to open flames, high temperatures, and excessive heat should be avoided to prevent overpressure and potential cylinder rupture. Fluoropolymers produced from PMVE exhibit excellent chemical resistance and maintain outstanding performance across a broad operating temperature range.
