Composition cork rolls and sheets are perhaps the most versatile of all cork products. These items are manufactured from natural cork grains and therefore maintain most of the same characteristics attributed to cork in its natural state. Cork rolls and sheets are used for many products, including bulletin and tack boards, gaskets and protective pads, underlayment and insulating material, coasters, hot pads, model, crafts and hobby needs, and much more.
Different cork grain sizes and distinctive formulations of binders are used in the manufacturing process to create composition cork rolls and sheets in grades and appearances to satisfy specific purposes and uses.
Benefits of Composition Cork
Composition cork materials have high oil resistancy, a high degree of compressibility with practically no lateral flow, an unusual degree of recoverability and a high degree of impermeability under relatively low bolting pressures. They also possess inherently high friction values and will withstand extremely high bolting pressures without crushing. Composition cork materials are generally recommended for use where sustained temperatures at the sealing line do not exceed 250°F, and are not to be used for the sealing of alkalies, inorganic acids, or oxidizing solutions.
Composition cork consists of binder that is typically the natural resins in cork, phenolic resins, protein, or other special polymeric binders. These binders coat each particle of cork and are joined together under pressure to form a solid mass.
