Definitions

• Fluorine-containing polymers are a commercially useful class of materials. Fluoropolymers include, for example, crosslmked fluoroelastomers and semi-crystalline or glassy fluoropolymers. Fluoropolymers are generally of high thermal stability and are particularly useful at high temperatures. They may also exhibit extreme toughness and flexibility at very low temperatures. Many of these fluoropolymers are almost totally insoluble in a wide variety of solvents, and are generally chemically resistant. Some have extremely low dielectric loss and high dielectric strength, and may have unique non-adhesive and low friction properties.
• Fluoroelastomers particularly the copolymers of vinylidene fluoride with other ethylenically unsaturated halogenated monomers such as hexafluoropropylene, have particular utility in high temperature applications such as seals, gaskets, and linings.
• Multi-layer constructions containing a fluoropolymer enjoy wide industrial application. Adhesion between the layers of a multi-layered article may need to meet various performance standards dependent on the use of the finished article. However, it is often difficult to establish high bond strengths when one of the layers is a fluoropolymer, in part because of the non-adhesive qualities of fluoropolymers.
