Characteristics of Glass Fiber Needle Mat: 1. Heat Resistance and Specification It 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 Insulation According 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/mhr℃ 3.Noncombustible Material The 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 Absorption When 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 Insulation Glass fiber is the best insulation material because it is able to
resist high temperature and has good mechanical property and high
chemical stability. 6.Anticorrosion Glass fiber can resist corrosion of strong acid and alkali.Its
functions will not be diminished after long-term use. 7.Good Restoring Force Glass 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 Rate Its moisture absorption rate is usually close to zero. 9.Lightweight and Soft Material In 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 Construction It 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 wall’s 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 appliances 4. 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.
