Balsa core material for composites
BALTEK®
Airex AG
Balsa is the only core material that comes from natural and renewable resources.
Sandwich structures using balsa create a particularly light and strong product. Its end-grain configuration creates optimal physical properties due to the honeycomb like cell structure.
The balsa tree is the fastest growing tree in the world. It can grow from a tiny seedling to an adult 90 feet high in about 5-7 years. It grows straight and tall, with a trunk of about 18 inches in diameter, and is topped by a lush crown of very large leaves.
Each balsa tree produces hundreds of thousands of seeds. These are carefully culled, and only the fittest are germinated in nurseries and planted on the farms.
The other ingredients for rapid healthy growth are contributed by nature: the rich Ecuadorian soil, rainfall that averages 90 inches a year and hot tropical sunlight.
