700HT Intumescent Mat

UNITECO Interat 700HT intumescent catalytic converter support mats with characteristics of both intumescent and non-intumescent mats will work as non-intumescent mat at low operating temperatures less than 350°C based on the spring-like ceramic fiber matrix to provide the holding force while behave as intumescent mat at temperature above 350°C based on holding force to the substrate provided by the small quantity of vermiculite particles within the fiber matrix compensate for thermal gap expansion of the outside shell and present robust performance at continuous working temperature from 750℃ to 950℃

UNITECO Interat 700HT intumescent catalytic converter support mats with characteristics of both intumescent and non-intumescent mats are suitable for mechanical support and insulation of gasoline engine with thin-wall and ultra-thin wall ceramic substrate as well as large diameter medium and heavy-duty diesel cordierite & AT substrates with low coefficient of thermal expansion in diesel emission control devices

UNITECO Interat 700HT intumescent catalytic converter support mats are widely used in the range of emission control devices including large diameter of diesel oxidation catalysts (DOC), diesel particulate filters (DPF), selective catalyst reduction units (SCR) as well as the underbody catalyst converters and close-coupled to underbody catalyst applications
