Vinylidene Fluoride
Used as monomer for PVDF polymers in coatings, membranes, and batteries; in refrigerants and propellants; in chemical synthesis for fluorinated compounds; in electronics for insulators; in medical devices for biocompatible materials.
Highly flammable gas, forms explosive mixtures with air; toxic by inhalation, irritates eyes and respiratory tract. Asphyxiant in high concentrations; avoid heat and oxidizers. Hazard Class 2.1; use PPE, ventilate, no ignition sources.
Supplied in pressurized cylinders or tanks with safety valves; store in well-ventilated areas away from heat per Sigma-Aldrich SDS.
