Impact & scratch resistance

Cork recovers more than 85% of its shape after compression, cycle after cycle, across millions of impacts. That makes it the material of choice for surfaces that must survive repeated shock without hardening or cracking — from playground tiles to furniture feet to helmet liners.

Synthetic foams compress out of spec. A yoga mat or helmet liner that starts at 10 mm can harden to a 3 mm pad after eighteen months of use, as the cells collapse and the material densifies. That failure mode is invisible until someone notices the mat no longer cushions a fall.

Cork's cellular geometry — roughly 40 million cells per cubic centimetre — gives it a fundamentally different response. Each cell compresses independently and rebounds when the load is removed. After millions of cycles, the rebound is still above 85%. The material does not densify because the cell walls do not fracture under the loads typical of impact protection.

For furniture and product design, natural cork blocks machine cleanly and hold fasteners without splitting. The same density that delivers impact resistance also provides a tactile surface that does not show scratches the way lacquered wood or painted metal does.
