Introduction: By applying high-count fiberglass, GFNF series has the excellent properties such as heat-isolation, fire-resistance, anti-corrosion and heat-preservation. It's the most characteristic and newest heat-preservation material of inorganic silicate at present. Feature (1) Lightness, heat resisting, low thermal capacity and low thermal conductivity, soft and excellent fire-isolation. (2) Anti-heat energy and heat stability. (3) Anti-mildew, anti-insect, un-scattered and good stretching resistance. (4) Excellent anti-ageing. (5) Excellent sound absorbability, adsorption and filtering. (6) It can be cut, sewn according to requirements and it's also easy to construct. Application: (1) This mat is widely used for wrapping material of all kinds of heat source (coal, electricity, oil, and gas) and heat-presentation of central air- conditioning pipelines. (2) It can be used as the materials for heat-isolation and fire-resistance. (3) It can be used as the materials for seal, sound absorption filtering and insulation. (4) Excellent material for heat-conducting, heat-presentation. (5) It can be used as materials for sound isolation, heat insulation and heat- resistance in vehicles, vessels and aircrafts. (6) It can also be used for touching fire and all kinds of flue in which the temperature is less than 600.
