Cork Mat 3mm 50mm (2 inch) Bulk Pack 100

Cork Mat 3mm thick, round 50mm diameter. Bulk pack of 100. Cork is a completely natural raw material with unique properties. More than half the world's cork comes from Portugal. The tree has a lifetime 170 - 200 years, and the harvesting of the bark is absolutely harmless to the tree. The bark grows back within 9 - 10 years and can then be re-harvested. More than 85% of its volume is filled with air, which makes it light, impermeable to liquids and gases, elastic and compressible, provides thermal and acoustic insulation, is a fire retardant and is highly abrasion-resistant. Cork sheets can be easily cut and are perfect for pin boards, model making and even acoustic insulation.
