Description
Only the barks of the trees are used and they are rasped after peeling. This tree is cultivated in tree nurseries and can be peeled 7 years after having been planted out. The rasped wood of the inner trunk is also used in the chipboard industry or for charcoal.
Application
Mimosa tanned leather provides a robust, light and slightly reddish leather, which is sensitive to light and darkens gradually. Today it is used in tanning in combination with oak bark especially for sole leather in the higher price segment and for sanitary shoes. Due to the long production time of this leather the production costs are quite high.
