PURITY ­ PERFORMANCE

Test results prove that ash content has LITTLE EFFECT ON GASKET PERFORMANCES, BUT TRACE IMPURITIES have a BIG impact on performance and TRACE ADDITIVES such as phosphorous, can greatly reduce oxidation weight loss rates. 98% purity mean up to 20,000 ppm of impurities, “DON’T CONFUSE PURITY WITH PERFORMANCE!”

Critical Impurity Element GRAFOIL Sheet
Chromium (Cr) < 5 ppm
Sodium (Na) < 150 ppm
Sulfur (S) < 500 ppm
