Polymer compositions intended for the manufacture of pipes for conveying hydrocarbons and articles based on these compositions |
摘要 |
Polymer compositions based on vinylidene fluoride resins which are particularly suitable for the manufacture of pipes for conveying hot hydrocarbons under pressure, comprising by weight; (A) from 60 to 80% of at least one PVDF homopolymer; (B) from 20 to 40% of at least one thermoplastic copolymer of vinylidene fluoride (VF2) and of at least one other fluoromonomer (for example hexafluoropropylene, chlorotrifluoroethylene or trifluoroethylene), containing approximately from 5 to 25% of this other monomer; and (C) a plasticizer, in proportions of 5 to 20% [relative to the total weight of the polymers (A) and (B)], preferably dibutyl sebacate or a polyester of molecular mass of between 1500 and 5000.
