Preoxidized filament

Product Introduction

Pre-oxygenated wool is an insulation material made of pre-oxidized wool (PAN-based pre-oxygenated wool) compounded by a special process, with extremely low density, which is one of the lightest materials currently used in the rail industry. The product processing process does not add any binder, the material is completely green and environmentally friendly. It is a non-combustible material.
