ACOUSTIC PERFORMANCE

The noise reduction is a function of material mass per unit area. Material thickness should be set to provide desired sound transmission loss. Patches at 2 mm thick are widely used over sheet metal holes.

ADHESION CHARACTERISTICS

When subjected to a 180° peel at a rate of 200 mm/min on a 25 mm wide test specimen, the material has a peel strength >10.0 N (4.0 N/cm) when applied to cold rolled steel.

ELEVATED TEMPERATURE

Material will withstand automotive bake cycles and still maintain its performance requirements.

FLEXIBILITY/

CONFORMABILITY

The material will remain flexible and conformable at temperatures

as low as -30°C.

FLAMMABILITY

Meets FMVSS 302, self-extinguishing
