Application

В самом названии войлока обозначено основное предназначение данного материала в машиностроении.  Данный материал предназначен для неподвижных уплотнительных устройств  — уплотняющих прокладок. Как правило, прокладки применяются для уплотнения  прилегающих поверхностей с целью герметизации.

Coarse wool felt for pads has a number of unique properties:

  • low thermal conductivity and thermoregulatory qualities;
  • excellent heat and noise insulation ability;
  • durability, resistance to mechanical, temperature and chemical influences;
  • complete environmental safety for humans and the environment;
  • naturalness, absence of chemical components in the composition;
  • elasticity, flexible structure of the material, but at the same time strength and wear resistance;
  • the felt does not burn, but only smolders.

Thanks to this, pads made of coarse felt have found wide application in a wide variety of areas.

Felt pads have high elasticity, soften impacts and reduce vibrations of mechanisms. Because of this, they are widely used to seal joints in fuel tanks, steering columns, gearbox plugs, filters and other joints.

Felt pads are resistant to sulfuric acid. This property is responsible for the widespread use of felt gaskets in chemical plants, as well as in petrochemical, steel and construction industries.

Очень широкое применение войлок грубошерстный для прокладок нашел как материал, который применяют для виброизоляции и шумоизоляции.  Он сегодня занимает первые места среди акустических материалов. Он обладает рядом характеристик, которые присущи звукопоглощающим материалам высокого класса. Используется для шумоизоляции   многими производителями  автомобилей, включая и все именитые немецкие фирмы. Которые,  также  используют  войлок в своих штатных решениях.

It is widely used in construction, and recently there has been a steady upward trend in the use of this material. This is due to the fashionable trend towards the use of environmentally friendly and natural materials.

Coarse wool felt for gaskets has a high density. Holds grease well. Has high elasticity. It is resistant to abrasion. Protects components and parts from dust and water.

Coarse wool felt for gaskets is produced in two grades, depending on the degree of compaction:

  • A - with a density of (0.32±0.02) g/cm;
  • B - with a density of (0.26±0.02) g/cm (for soft pads);
