Isorights EcoFrax 550 vermiculite intumescent catalytic converter support mat made of suitable content of vermiculite and AES (Alkali Earth Silicate) fiber through wet process paper making technique, the AES fiber with the composition of Calcium and Magnesium Silicate (CaO+MgO+SiO2) which could be degradable after inhaled into human body is much more environmentally friendly to human body than the regular (RCF) refractory ceramic fiber and PCW (polycrystalline wool fiber) mats.

Isorights EcoFrax 550 vermiculite intumescent catalytic converter support mat as kind of cost-effective and environmentally friendly exhaust catalyst support mat is especially designed of Euro 4 gasoline (TWC) three-way catalytic converter including underbody catalyst, manifold catalyst as well as close-coupled catalyst in the European market.
