Product introduction

The SoliFelt™ product range consists of latex bonded fiber board products which remain flexible after production. As a result, SoliFelt™ can be used in applications where the end user requires the strength of a board product with the flexibility and resiliency to ensure a mechanical seal.

For the most demanding applications we proudly present SoliFelt™ ZR-grade, with a classification temperature of 1430°C. As a result it provides a proven solution in applications operating continuously up to 1300°C. The maximum continuous use temperature is a guideline and only applicable in a clean oxidizing atmosphere.

All SoliFelt™ products are manufactured from true Generation III, ultra clean and fine SoliWool fiber and organic binders. As a result SoliFelt™ has a very smooth surface, close dimension tolerances, exceptionally low dust, high handling strength, better thermal insulating performance and greater resiliency after compression thanks to the superior fiber index.

Typical applications

  • Gasket for expansion joints between pre-casted shapes and IFB linings
  • Gasket for ladles and ingots in the steel industry
  • Veneering modules production
  • General technical insulation of furnaces and technical installations

Benefits

  • High fiber index
  • Low shot technology
  • Excellent insulation performance
  • High handling strength
  • Close dimensional tolerance
  • Smooth surface and low dust
  • Easy die-cutting for high temperature gaskets
  • Excellent thermal stability
