Characteristics of Fiberglass Needle Mat

1. Heat Resistance and SpecificationIt can resist high temperature of 700, 850 and 1000 and be cut into different thickness (3mm~100mm) according to the requirements of customers.2. Excellent Heat InsulationAccording to physical principle, the thermal conductivity rate of gas is smaller than that of solid.For excellent heat insulation materials, there should be many air pockets inside the materials. As an excellent heat insulation material, the glass fiber cotton has innumerable tiny air pockets, and its fibers are arranged irregularly with a thermal conductivity coefficient between 0.2~0.040 kcal/mhr3.Noncombustible MaterialThe main element of glass fiber is silicide (over 50%) which is noncombustible and will not deform or embrittle even under high temperature for 3 consecutive hours.4. Good Sound AbsorptionWhen the sound wave enters the glass fiber cotton, its energy will be absorbed by the cotton due to the friction between fibers and different sizes of air pockets.? Generally speaking, the sound absorbing coefficient of the glass fiber cotton is higher than 90%. Therefore, it is a good material for preventing the interference of noise.5. High InsulationGlass fiber is the best insulation material because it is able to resist high temperature and has good mechanical property and high chemical stability.6.AnticorrosionGlass fiber can resist corrosion of strong acid and alkali.Its functions will not be diminished after long-term use.7.Good Restoring ForceGlass fiber contains countless air pockets, so it has excellent restoring force to resist any impact and vibration with a tensile strength over 1.0 kg.8.Low Moisture Absorption RateIts moisture absorption rate is usually close to zero.9.Lightweight and Soft MaterialIn comparison with the other heat insulation materials, glass fiber products are the lightest and softest material.? If installed on machinery, it can help reduce the burden of weight and vibration.10.Simple and Easy ConstructionIt is simple and easy to use glass fiber for all kinds of thermal insulation, heat insulation, refractory and sound absorbing engineering or products.

Application:1. Building: for roofing, flooring and walls thermal and acoustical insulation, guarantee the building object be the energy-saving type.2. Ship and automobiles: replace the structure and shell body of the metal and pure plastic wooden materials, reduce the needed driving force, save energy, extend the life.3. Heat insulation for industry equipment, parts and duct and household electrical appliances4. Aviation and space flight: thermal and acoustic insulation for thin panel and nail-board by fire-proofing fabrics, used for the thermal insulation and sound absorption of engine system, Absorbing noises and purifies the tail gas.5. Traffic: widely used in railway, highway, sports ground, water construction, environment-protection project, would shorten the construction period, extend the using life.
