Cork Powder
Sub-millimetre suberin-rich powder for fillers, friction compounds and specialty chemistry.
Cork powder is a sustainable and highly versatile cork raw material used in a wide range of industrial applications. At Dimas & Silva Cork Group, we upgrade cork powder into a high-value technical product through calibrated particle-size classification and moisture stabilization processes designed to guarantee consistent quality and industrial performance from batch to batch.
Our cork powder is widely used in paints, coatings, cork spray systems, and technical agglomeration applications. It is an important raw material for thermal and acoustic cork coatings, decorative eco-friendly paints, anti-condensation solutions, and natural insulation systems used in sustainable construction projects.
Another major application for cork powder is technical agglomeration for marine decking systems, including boats, yachts, and cruise ships, where cork provides lightweight structure, elasticity, comfort underfoot, thermal insulation, anti-slip properties, and resistance to moisture and marine environments.
Additional applications include: NBR and EPDM rubber compounds, composite materials, friction materials, sealants and fillers, bio-based industrial formulations, lightweight construction materials, and sustainable industrial compounds.
Dimas & Silva Cork Group supplies high-quality cork powder solutions from Portugal to customers worldwide operating in coatings, construction, marine decking, composites, footwear, and industrial manufacturing sectors.
