MULTI-LAYER ARTICLES INCLUDING A FLUOROPLASTIC LAYER

摘要

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.ordm.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 polymer s may optionally have melting points greater than 200.ordm.C.
