Abstract
A multi-layer article featuring a fluoroplastic layer bonded to a non-fluorinated polymer layer in which the fluoroplastic has a melting point of at least 200° C. and contains interpolymerized units of at least TFE and VDF, the amount of VDF being at least 0.1% by weight, but less than than 20% by weight. Also useful are fluoroplastics containing at least TFE and VDF in which the amount of VDF units is between 0.1 and 15% by weight. Such polymers may optionally have melting points greater than 200° C.
