  • Lined pipes and fittings, associated forming method, and method of improving the chlorine resistance of high density polyethylene pipes
    Patent number: 10213980
    Abstract: A lined pipe or fitting includes an outer layer containing high density polyethylene, and an inner layer containing a blend of poly(phenylene ether), polystyrene, and, optionally, a hydrogenated block copolymer. Relative to corresponding pipes and fittings made from high density polyethylene alone, the lined pipes and fittings exhibit improved resistance to chlorine and chlorine derivatives.
    Type: Grant

  • Thermoplastic composition comprising a compatibilized polyphenylene ether-polyamide base resin and electroconductive carbon black
    Patent number: 5977240
    Abstract: The present invention deals with a thermoplastic composition comprising (a) a compatibilized polyphenylene ether-polyamide base resin, and (b) 1-7 parts by weight per 100 parts by weight of (a) of an electroconductive carbon black, with an Izod notched impact strength of more than 15 kJ/m.sup.2 and a volume resistivity of less than 10.sup.6 Ohm.cm.The compositions of the invention are suitable for molding objects which can easily be painted by an electrostatic coating process.The invention further provides a process for the preparation of the composition of the invention comprising at least two steps. In the first step the base resin is formed. In a further step the carbon black is incorporated in the base resin.The invention further relates to articles formed out of the composition of the invention and to such articles which have been painted by an electrostatic coating process.
