The combination of high performance fiber and low-content-vermiculite, together with low-content of organic binder, endow micro-intumescent mat unique thermal performance: behave as non-intumescent mat under low temperature and as intumescent mat under high temperature, thus ensure its excellent performance in 250 to 750 deg.C.

After optimization, KY860 shows greater durability than KY800, achieve additional 50% performance raise in aging test.

KY800/860 series have been widely used in diesel exhaust after-treatment  either tube design or box design in China OEM Market. Over 600,000 diesel vehicles have been successfully assembled with KY800/860 and NO NEGATIVE feedback till now.
