Cork is no longer just for wine. Amorim Cork Composites has launched a new blend of cork and thermoplastic that it says improves sound insulation while being more durable than traditional materials in an automobile. For years, several automakers have used shredded, shredded textiles from cars that are no longer worn, to insulate vehicles.
Cork does a much better job
This new product, called MAC020 Heavy Mass Layer, is 100% recyclable. Traditional materials, normally used in this sector, cannot claim the same. According to Amorim, this product can be used in cars, trains, buses and caravans. In fact, everything that needs to be isolated to prevent outside noise from entering the cabin.
No more expensive
This is the latest step towards building sustainable automotive solutions that go beyond the obvious. Another example is a vegan interior, although this particular route could be a decoy.
The Portuguese company Amorim has been manufacturing cork stoppers for over 130 years, and the composites department was created to look into other areas where cork could be useful. As stated, the MAC020 is not 100% cork, but a hybrid including thermoplastics. These plastics come from recycling, which further reduces waste.
Better thermal insulation
According to Mr. Amorim, this material is very suitable for cars because of its lightness and durability. It also has thermal and acoustic insulation properties, making it ideal for electric vehicle applications. Contrary to popular belief, electric vehicles are not as quiet as one might think. Since there is no motor to muffle exterior and interior noise, sound intrusions are often more pronounced.
No need to cut down a tree to harvest cork
For every ton of cork produced, 73 tons of CO2 are sequestered by the cork oak forest. No trees are felled to produce cork. Cork oaks are debarked by hand so as not to damage them. strives to use more sustainable materials in the manufacturing process. Even at the top of the range there is enough demand for manufacturers like Bentley to offer eco-friendly options. Combined with Porsche’s very promising synthetic fuel, it’s safe to say that a 911 with a tweed interior and cork insulation could be even greener than a Taycan.
