A PROCESS FOR MAKING HIGH PURITY TRANSLUCENT PERFLUOROELASTOMER ARTICLES |
摘要 |
Perfluoroelastomer articles comprising perfluoroelastomers having copolymerized units of tetrafluoroethylene, a perfluoro(vinyl ether), and a nitrile-containing cure site monomer are at least partially cured and then exposed in air to temperatures between 150 DEG and 350 DEG C for 1 to 70 hours in order to lighten the article's color and render it translucent or transparent. The resulting articles contain less than 200 ppm metals. |
