Material description
Technical felt with a thickness of 4 mm is a durable non-woven fabric made from a blend of natural and synthetic fibers. Thanks to the high wool content (70%), it retains excellent thermal insulation properties, is strong, flexible, and at the same time easily workable. Polyester gives the material greater dimensional stability and wear resistance.
Suitable for production:
decorative and hobby projects
upholstery and fillings
industrial cutouts, gaskets, and insulations
mats for machines and tools
packaging and protective elements
