Looking for Fiberglass Needle Punch Felt in Thailand? Introducing general spec of E-glass fiberglass needle punch mat available in Thailand. Thickness can be as thin as 3mm.
What is Needle Punch felt? What is it made of?
E – Glass fiber is an inorganic fiber that is thermally, electrically, and chemically stable. Needle punch felt is made by opening the long glass fibers into wool.
It is made into a felt shape after undergoing a needling process. Due to its stability and relatively low cost, it is used in a wide range of industrial applications. In general, no binder is used for the felt.
What is the characteristics and its applications?
Needle punch felt made from mainly E glass fiber are used as a material for heat insulation and sound absorption especially in high-temperature areas. The characteristics of E long glass fiber (non combustibility, electrical insulation) and the shape of the needle punch felt brings the following performance.
1. Heat resistance can be at a safe operating temperature of 650 ℃ or less.
2. Workability is high with safety. It is easy to cut and does not contain asbestos.
3. In general, wide variety of size are available.
| Thickness (t) | Density (g/m2) | Width (mm) | Length (m) |
| 3～25 | 300～3500 | 1,000～2,000 | 5～30 |
Its applications are wide range such as;
Automobiles and relate industry: ships, automobile mufflers, agricultural machine, construction machine mufflers, thermal insulation materials for diesel engines
Natural resource industry: Insulating material for gas equipment/insulating material for oil equipment/sealing material for gas water heaters
Boiler/Furnace Industry: Insulation materials for various boilers, insulation curtain for industrial furnaces, etc.
Sound-absorbing purposes: interior materials for machine rooms, heat-insulating sound-absorbing materials for factory equipment
FYI, what is E Glass?
There are several types of glasses invented for the glass fiber use. For example,
“C” (stands for “Chemical”) glass has an excellent chemical resistance.
“S” (stands for “strong”) glass has high strength.
“E” glass is electric glass, which has high dielectric breakdown characteristics.
It is an alkali-free. E-glass fiber is made by spinning this type of glass to a diameter of around 9 to 13 μm in general. Since this fiber has high strength and elastic modulus, it is used mainly for FRP with silane or borane surface treatment.
How Are Needle Punch Felt Mats Manufactured?
Needle punch mats are industrial insulation materials primarily made from E-glass fibers. These fibers are mechanically interlocked using special needles (needles punches) without the use of adhesives, ensuring stable performance even in high-temperature environments.
1. Raw Material Preparation
E-glass fibers are used as the main raw material. They are fed into the production line, where they are loosened and processed into a cotton-like form.
2. Carding (Fiber Opening and Alignment)
A carding machine is used to further separate and align the fibers, forming a thin, uniform layer. This process ensures consistent fiber density, improving the strength and insulation performance of the final product.
3. Layering
Multiple layers are stacked according to the required thickness and density. By adjusting the layering process, the strength and thermal insulation properties of the mat can be customized.
4. Needle Punching (Mechanical Interlocking)
Special needles punch through the material thousands of times per square meter, interlocking the fibers together. This step enhances the durability and heat resistance of the mat.
5. Finishing and Cutting
Additional treatments, such as heat resistance enhancement or water-repellent processing, may be applied as needed. The mats are then cut into the required sizes before being shipped.
Through this manufacturing process, needle punch mats achieve a lightweight structure with excellent thermal insulation performance, making them ideal for high-temperature environments.
