  • Polyvinylidene fluoride compositions of improved flexibility and their use, particularly in the manufacture of flexible tubes
    Patent number: 4584215
    Abstract: Polyvinylidene fluoride compositions have their flexibility improved by incorporation therewith of a minor proportion of one or more esters formed between at least one aliphatic diol such as 2,2-dimethyl 1,3-propanediol, a polyethylene glycol, propylene glycol, a polypropylene glycol, tetramethyleneglycol, a polytetramethyleneglycol or an aliphatic triol such as glycerol, and a monocarboxylic acid of aliphatic chain containing 2 to 10 carbon atoms or a monocarboxylic acid of aromatic radical such as benzoic acid. Polyvinylidene fluorides of improved flexibility are particularly useful for manufacturing flexible tubes for conveying various fluids such as, for example, hot water, chemical products, hydrocarbons.
