 Fiberglass knitting felt
|
|
 Production:
Fiberglass knitting felt adopt E-Fiberglass, by shear machine incise with 8-10mm fiber, by filling-engine break up imperceptibility feather mat. Into pinprick machine stitchwork, and become production. |
Advantage:
Fiberglass knitting felt adopt e-fiberglass, main element is Al2O3 and CaO. Have excellent heat-resistant, tensile strength,tenacity, fire-resistant and rot-resistant, insulation is very good. It has excellent muffle and heat insulation. |

Application:
|
Fiberglass knitting felt plunges the resin to process plate-type , It could especially supply good effect of the house building and the air conditioner liner to heat and sound insulation material.
Fiberglass knitting felt's surface pass the fitting aluminum foil or plastic cloth to produce belt-shaped. Also supply the hot and cold tube road and the underground pipeline heat preservation and the protection uses.
Fiberglass knitting felt may use for thermostable, the obdurability, fireproof materials and so on. Eg. special request of the automobile roof board, the bonnet protection heat insulation, the damper sound-insulated, the ships industry, the boiler industry also can obtain ideally satisfies, it also instead of asbestos product. |
