Felt is manufactured from a variety of materials such as wool, synthetic fibres, cow's hair and coconut fibres. The raw materials to be used and the density of the felt to be made are determined according to the application for which the felt is to be used and the specifications required. For instance, felt can be soft and easily shaped, but it can also be as hard as steel. The sophisticated production techniques used allow felt to be given its specific properties.
All types of felt can be supplied in many different colours, thicknesses and densities and in the most wide-ranging forms, such as strips, rings, discs, rolls etc. The properties can vary from static to temperature-resistant and from water-repellent to self-adhesive.
