Clean Diesel Made Possible Corning® DuraTrap® AT Filters Particulate filters for diesel emissions systems Diesel engines are an increasingly popular choice for fuel-efficient passenger cars and light-duty trucks. Advanced filters support the drive to improve fuel efficiency and meet tighter regulations. Corning® DuraTrap® AT diesel particulate filters use advanced materials and monolithic design to deliver: • High filtration efficiency • Excellent pressure drop performance • Enhanced durability Porous Material* CTEc (x10-7/˚C) Intrinsic Density (g/cm3) Volumetric Heat Capacity @ 500˚C (J/cm3 K) Corning’s aluminum titanate (AT) composition enables high performance light-duty filters by combining low coefficient of thermal expansion (CTE) with high hea

Corning® DuraTrap® AT Filters Performance Corning DuraTrap® AT filters use a stabilized aluminum titanate for outstanding performance and durability. Introduced in 2005, these filters have been proven in millions of vehicles. Corning’s aluminum titanate material provides low thermal expansion to enable durable monolithic construction that allows for: • Low pressure drop and excellent regeneration efficiency to help improve fuel consumption • Increased ash storage capacity and larger filtration surface area compared to segmented filters Additionally, its engineered pore structure enables customers...
