Fiberglass Needle Mat High Silica Silencer Repacking Material 25MM 130KG 1800℉
This amorphous silica glass fibre felts is carded by silica fibers to produce a high volume batt, is mechanically needled to bond the fibers which results in a dimensionally stable felt, possessing excellent thermal and acoustic insulating properties, it is completely free of chemical binder. The needle system and the fibres diameter gives the final blanket high air permeability, high density, great thermal insulating capacity and acoustic absorption. The high level of silica gives the product increased compactness, flexibility and resistance to high temperatures.
High silica needle mats are suitable for continuous used at temperature up to 1800℉. Its properties include low coefficient of thermal conduction, low heat storage and absolute in combustibility. High silica needle mat is asbestos free and not hazardous to health. This needle felt consists of silica fibres that will take very high temperatures and pressures. It is suitable for confined spaces, or as a thermal barrier in conjunction.
Continuous working temp.: 1800degree F
Instant working temp: 2200degree F
