Product Description

Composition Cork:

When it comes to sustainable and eco-friendly materials, cork stands out as a versatile and environmentally conscious choice. Portugal is renowned for its production of high-quality cork products, from cork board material to cork floor tiles and everything in between.

Cork is harvested from the bark of cork oak trees without harming the tree itself, making it a renewable resource. The production process is eco-friendly, with minimal waste generated during manufacturing. This aligns perfectly with the growing demand for green building materials and sustainable practices.

Composition Cork Constituents

  • Suberin: Approximately 40% of composition cork consists of suberin, a hydrophobic substance that helps reduce water penetration.
  • Lignin: Comprising 22%, lignin provides structural support.
  • Polysaccharides (Cellulose and Hemicellulose): These make up 18% of the material.
  • Extractables: About 15% of composition cork includes extractable components.
  • Others: The remaining percentage includes various additional constituents 1.

Applications of Composition Cork

Composition cork sheets have various applications due to their unique properties. Some common applications include:

  1. Flooring: Composition cork sheets are often used as an eco-friendly flooring material. They provide cushioning underfoot, insulation against temperature changes, and sound absorption properties, making them suitable for residential and commercial spaces.

  2. Footbeds and Insoles: Cork is often used in the construction of footbeds and insoles for shoes. Its natural cushioning properties provide comfort and support for the wearer, helping to absorb impact and reduce foot fatigue. Cork footbeds also mold to the shape of the wearer's foot over time, providing a personalized fit.

  3. Heel Lifts and Wedges: In some shoe designs, cork is used to create heel lifts or wedges to provide additional support and cushioning under the heel. These components can help to improve stability and alignment for the wearer.

  4. Lasts: In last making, which is the process of creating the form around which a shoe is constructed, cork is sometimes used as a filling material. It can be molded and shaped to create custom lasts that match the contours of the foot, ensuring a better fit for the finished shoe.

  5. Midsoles and Outsoles: While less common than other materials like rubber or EVA foam, cork can also be used in the construction of midsoles or outsoles for certain types of footwear. Cork midsoles can provide lightweight cushioning and flexibility, while cork outsoles offer durability and traction.

  6. Wall Coverings: These sheets can be used as wall coverings to add texture and warmth to interior spaces. They can also act as acoustic panels, absorbing sound and reducing echo in rooms.

  7. Bulletin Boards: Composition cork sheets are commonly used to make bulletin boards in homes, offices, schools, and community centers. Pins and tacks can be easily inserted into the cork surface to display notes, memos, and other materials.

  8. Crafts and DIY Projects: Cork sheets are popular materials for various crafts and DIY projects. They can be easily cut, shaped, and glued onto surfaces to create coasters, trivets, placemats, and other decorative items.

  9. Gaskets and Seals: Due to their compressibility and resistance to moisture, composition cork sheets are used in the manufacturing of gaskets and seals for automotive, industrial, and aerospace applications.

  10. Musical Instruments: Cork sheets are used in the construction of musical instruments, such as saxophones, clarinets, and oboes. They are often used as key pads and damping materials to provide airtight seals and improve sound quality.

  11. Underlayment: Composition cork sheets are used as underlayment for laminate, hardwood, and engineered wood flooring. They provide a smooth and cushioned surface, as well as thermal and sound insulation properties.

  12. Model Building: Model builders often use cork sheets to create landscapes, terrain, and building foundations in architectural and diorama projects.

  13. Packaging: Cork sheets can be used as protective packaging material for delicate items during shipping and transportation. They provide cushioning and shock absorption to prevent damage.

  14. Thermal Insulation: Due to their low thermal conductivity, composition cork sheets are used as insulation material in applications where temperature control is important, such as refrigeration units and HVAC systems.
