Composite material, manufacturing process therefor and uses thereof

A composite material obtainable by a process for producing a composite material, the process comprising the steps of:

• providing mm-sized particles comprising at least particles of a porous optionally at least partially compressed open-cell melamine formaldehyde resin and mm-sized particles of at least one non-rigid foamed resin;
• mixing said particles with at least one reactive adhesive in a concentration of 6 to 18 g of reactive adhesive per 100 g of mm-sized particles;
• reacting said reactive adhesive with said particles in the presence of aerial moisture thereby bonding said particles together during said mixing process;
• transporting said mixture into a mould;
• and irreversibly compressing said mixture to a block in a mould without additional heat to a density greater than 50 kg/m3 to form a block of said composite material.

A laminate comprising a composite material, said composite material being obtainable by a process for producing a composite material, the process comprising the steps of:

• providing mm-sized particles comprising at least particles of a porous optionally at least partially compressed open-cell melamine formaldehyde resin and mm-sized particles of at least one non-rigid foamed resin;
• mixing said particles with at least one reactive adhesive in a concentration of 6 to 18 g of reactive adhesive per 100 g of mm-sized particles;
• reacting said reactive adhesive with said particles in the presence of aerial moisture thereby bonding said particles together during said mixing process;
• transporting said mixture into a mould;
• and irreversibly compressing said mixture to a block in a mould without additional heat to a density greater than 50 kg/m3 to form a block of said composite material.

A method of using a composite material for polishing and/or cleaning applications with a liquid, said composite material being obtainable by a process for producing a composite material, the process comprising the steps of:

• providing mm-sized particles comprising at least particles of a porous optionally at least partially compressed open-cell melamine formaldehyde resin and mm-sized particles of at least one non-rigid foamed resin;
• mixing said particles with at least one reactive adhesive in a concentration of 6 to 18 g of reactive adhesive per 100 g of mm-sized particles;
• reacting said reactive adhesive with said particles in the presence of aerial moisture thereby bonding said particles together during said mixing process;
• transporting said mixture into a mould;
• and irreversibly compressing said mixture to a block in a mould without additional heat to a density greater than 50 kg/m3 to form a block of said composite material.
