Perma-fil E'Glass Wool

Construction:

Saveguard Perma-fil E’Glass Wool is manufactured from drawn continuous filament E’Glass yarns, that are cut to the required staple length. The staple fibres are then processed using traditional textile machinery to open the fibres and produce a high volume blown wool. Perma-fil Glass Wool's possesses outstanding thermal and acoustic insulation properties and are used primarily in automotive exhaust silencer applications.

Properties:

Glass Yarns have a minimal amount of surface dressing to assist in processing, this is usually organic i.e. starch or silane and will disappear at temperatures above 200C. Without effecting the performance of the Glass Fibre.

Untreated E’Glass Fibres are suitable for continuous use at temperatures of up to 600C in exhaust applications however tensile strength continues to reduce noticeably as temperatures increase above 400C .

Glass Fibres are:

are resistant to oils, solvents and most chemicals although contact with hydrofluoric acids, strong alkalis and live steam should be avoided.

are non combustible.

have a low thermal conductivity

Colour:

Black/Dark Grey
