Several models produced by Volkswagen in North America use BASF Basot.
TG melamine resin foam is used as a sound-absorbing material
for the EA888 engine.
Bastot? TG is a thermoset polymer foam specially developed for the thermoforming process, which is mainly used to produce three-dimensional parts with complex shapes as well as customized parts
for tight spaces.
During the thermoforming process, non-woven materials can be attached to the foam surface to enhance the material properties
.
Using Barths in the hood? Foam solves several challenges faced by automotive manufacturers in one fell swoop: it provides excellent sound absorption and flame retardancy in the hot environment of the engine compartment, while reducing the weight of
the hood.
Its open-cell foam structure is particularly conducive to the absorption
of mid- and high-frequency sounds.
The nonwoven wool on the foam surface further improves sound absorption over
the entire frequency range.
Moreover, Basott? It also improves the flame retardancy of the hood and prevents continuous combustion of open flames, meeting the requirements of
UL 94 V-0 fire rating.
Bastot? Foam maintains excellent NVH properties
at temperatures up to 460°F (240°C).
Bastot? With a density of only 9kg/m3, the TG is much lower than the density of conventional soundproofing materials in the engine compartment, helping to reduce fuel consumption and CO2 emissions
