Product Description


Continuous monofilament glass fibre material, capable of withstanding thermal shock and vibration and showing good recovery from compression. The material is stable in arduous environments, does not accelerate corrosion of metallic components and exhibits excellent acoustic properties, making it suitable for use in hot silencing applications in the presence of high gas flow-rates. Examples include GT exhausts silencing, steam vent silencing and compressed air bleed silencing. Also used in other specialist applications, including hot/cold gas filtration, lubrication in metal extrusion processes, etc.
