I am reviewing ball valve specs from supplier in China and they are using seals made of polyphenyl PPL. I can find little or no information on this material to judge is suitability for use on boiler and pressure vessel piping. The valve supplier sent me a spec sheet that is little or no use. Anyone have any info on this stuff?
