Huntsman Automotive - ACOUSTIFLEX S

Supplier: Huntsman Polyurethanes

ACOUSTIFLEX S is stiff, self-supporting MDI-based foam, typically used for the engine compartment as a bonnet liner, as well as for the engine-side dashboard and as a transmission tunnel insulator. It is lighter weight (up to 2/3 less) than competing fibrous materials and, yet, is stiff enough that it secures easily it to the bonnet, simplifying underhood assembly and increasing production efficiency for OEMs.

Price Guide: POA

Self-supporting acoustic bonnet liner

Huntsman testing indicates that components made with ACOUSTIFLEX? S perform better than a range of competitive materials, including fibrous materials. ACOUSTIFLEX S withstands climate cycle tests for bonnet liners, including high heat and humidity, without shrinkage. Moreover, it can be formulated to meet a wide variety of fire resistance requirements, from MVSS 302 to non-burning.

Sold as a system, its batch-block processing is much simpler and requires much lower capital expenditure than glass fibre set-ups.
