Abstract:

A composite article is provided which includes a fluoropolymer intimately bonded to a component including a substantially non-fluorinated thermoplastic having pendant phenolic groups in combination with a base. Increased adhesion is observed by a greater peel strength value between the fluoropolymer component and a non-fluorinated thermoplastic having pendant phenolic groups.

International Classification:

B32B 2700

US Classification:

428421, 428422, 428 357

Abstract:

A method for increasing the adhesion of a first layer comprising a fluoropolymer substantially free of interpolymerized units derived from vinylidene fluoride to a second layer comprising a curable elastomer is described. The method comprises adding a dehydrofluorinating composition to the curable elastomer, contacting the layers and curing the layered article so formed. The resulting multilayer compositions and articles are also disclosed.

Abstract:

Curable fluoroelastomer compositions having improved compression set after curing are provided, as well as compositions that are of relatively high purity. These compositions include a hydrogen-containing fluoroelastomer having interpolymerized units derived from a cure-site monomer, a curative (optionally with a co-agent), and an organo-onium. When the fluoroelastomer contains units derived from vinylidene fluoride, the composition is essentially free from an inorganic acid acceptor. Methods of improving the compression of cured fluoroelastomer and cured fluoroelastomers having improved compression set are also provided.
