Agglomerated cork blocks are made from cork granules bonded together with a polyurethane binder and pressure/heat treated to produce a very strong and flexible product that retains the characteristics of the natural cork, i.e. flexibility, resilience to compression and so on. The cork blocks are cut into sheets with any thickness required above 1.0mm up to 27mm The usual sheet sizes are 945*635mm.This material has a high density of around 230 kgm3.
