TECHNYL PURE J 219HT V35 BK is a high temperature polyamide, reinforced with 35% of glass fibers, organic heat stabilized for injection moulding. This grade offers a clean formula free of additives containing halogens and other substances that have the potential to release metallic ions, as metallic ions are known to negatively affect the electrochemical reaction in a PEM Fuel Cell Stack. For this grade a metallic ion content < 8 ppm is guaranteed, based on internal ion migration analysis. Thanks to the innovative formulation it offers lower moisture absorption, improved electrical insulation, higher dimensional stability and good heat stability compared to standard PA66 compounds.
