Is Cork a good material?
Mechanical strength & Durability: Cork has high mechanical strength between -80C and 140C. Cork is extremely durable and has a high friction coefficient, so it will survive repeated impacts or rubbing/abrasion extremely well. Hypoallergenic: Cork does not absorb dust, so is ideal for use as flooring and wall coverings.
