Volkswagen has chosen BASF’s sound-absorbing Basotect TG melamine foam for the acoustic layer in the Volkswagen EA888 engine for the Jetta, Golf, Passat, Tiguan, and Beetle models produced in North America.

Basotect TG is the only thermoset melamine foam, which is specifically manufactured for thermoforming in order to make sophisticated three-dimensional components and customised elements for tight spaces.

The use of Basotect on the engine cover helps to address multiple challenges faced by automotive manufacturers. It provides superior noise absorption, flame resistance and weight reduction in the high heat environment of the engine compartment, BASF informs in a statement.

Because of its open-cell, fine foam structure, the sound absorption values in the medium and high frequency ranges are very good. The use of a non-woven fleece covering the BASF foam helps increase the noise insulation over the whole range of frequencies. The acoustic insulation ensures Volkswagen drivers and passengers will have a superior driving experience.

Basotect makes the engine cover flame-retardant and prevents it from maintaining a flame. These fire resistant properties aid in Basotect’s ability to meet the UL 94 V-0 fire rating. The BASF foam can withstand temperatures up to 460 ºF (240 °C) while maintaining its NVH properties. Basotect TG is also much lighter than conventional insulating materials used in under-hood applications, which is highly desirable as it reduces both fuel consumption and CO2 emissions.

Volkswagen’s EA888 engine with four cylinders has set the benchmark for small-displacement turbocharged engines. Designed to be lighter and more fuel-efficient, the new EA888 Gen 3 is turbocharged and the direct-injection four-cylinder’s additional low-speed torque has also enhanced the performance of the car.

Holli Woodard, market development specialist for Basotect in North America said, “In order to meet the ever-tightening North American automotive fuel efficiency and emission standards, smaller, higher-performing and direct-injection engines are being used in today’s automotive manufacturing. These engines create higher levels of heat and noise that impact the driving comfort. Car manufacturers and suppliers are increasingly looking for new materials to solve this challenge.” (GK)
