While some conventional insulation like e.g. silica fibers, textile glass fibers, mineral wool or ceramic fiber materials withstand the very high temperatures at the exhaust tract, the insulation properties are 3- to 4-times poorer compared to Microporous.
No comparable product offers better thermal insulation properties in the relevant temperature range than Microporous.
Clearly slimmer insulations can be achieved with Microporous. An insulation thickness of 3 – 4 mm substantially reduces the surface temperature of the parts and temperature management to the CAT or DPF (diesel particle filter) is effectively stabilised.
Beside the thermal properties, Microporous also slightly improves the acoustic characteristics in double-wall systems and thus offers a further benefit.
Application of Microporous
In the automotive industry, microporous offers highly effective thermal insulation in the:
- Entry and exit cones in the catalytic converters (CAT)
- Diesel particle filter (DPF)
Further applications in the area of fuel cells, latent heat storage and bearing mats for catalytic converters are intensively under development.
Particularly for these applications, Jay's offer Microporous products.
In most cases, microporous insulation is integrated into the gap between two half shells. The insulation completely follows the three-dimensional form of the shells. Thus almost all geometrical forms can be represented.
Microporous is supplied with different coatings that guarantee a trouble-free installation and welding of the parts. The coating dissolves completely during the process.
The advantages at a glance
- 3-4 times better insulation than conventional product for exhaust
systems
- reduces surface temperature dramatically
- reduces the insulation thicknesses and thus the thickness and/or
size of the construction
- high pressure resistance, therefore forming integration in a
sandwich system possible
- high weight savings
- vibration resistant
- not flammable
- improves acoustic characteristics
- reduces design cost
- reduces part variety – e.g. no heat shield necessary
- almost all forms can be utilised individually
- simple, clean handling and processing
- environment-friendly
