Roller has hard roller core (10) with outer elastic cladding (12). The cladding has elastic matrix material (16) with embedded fibers (19) with diameter of≤800 nm, so that outer surface (20) of the cladding is highly polished with Ra value of≤0.6 microns. The elastic cladding has thickness of 3-20 mm. The matrix material also has embedded powder bulking materials (17) with outer dimensions of≤1 micron at least in one direction. The paper web polishing roller has embedded fibers in the elastic matrix cladding material with a diameter of≤500 nm, (preferably≤200 nm). The outer dimensions of the embedded powder materials are≤800 nm in at least one direction, (preferably≤200 nm). The powder materials are in round or spherical particles, at least partially of carbon. The fibers are carbon fibers. The materials for the fibers and the bulking powders have a thermal conductivity which is higher than the matrix material, and they are evenly distributed through the matrix. The polished elastic cladding surface has a roughness value Ra of≤0.5 microns, (preferably≤0.2 microns, more preferably≤0.1 microns). An Independent claim is included for a roller production process, where the elastic cladding is formed with embedded fibers and bulking powders. |
