Catalyst Substrate

The catalyst portion of a catalytic converter is comprised of three main components: (1) the substrate; (2) the washcoat; and, (3) the catalytic components. The substrate is the 'core' of the catalytic converter. It can be made of ceramic, metal foil or wire mesh. The substrate contains numerous small flow-through channels (called "cells") through which the exhaust gases pass. The substrate is sized - both its volume and its cell density - specific to the engine and associated exhaust application. The function of the substrate is to have the applicable volume of exhaust gas pass through it while minimizing flow backpressure, and to provide a large surface area to be coated with washcoat and catalytic metals.

Hypercat's long-term close-knit partnerships with various vendors allows us to offer an array of finished products including:
