Main characteristics of fiberglass needle felt

1. Good thermal insulation: According to physical principles, the thermal conductivity of gas is low, and there are many air pockets inside excellent thermal insulation materials. Fiberglass needled cotton contains countless fine gases, and the fibers are arranged irregularly. It is an excellent thermal insulation material with a thermal conductivity coefficient of 0.2 to 0.040 kcal/mhr. c;

2. Does not burn: The main component of fiberglass is silicide (more than 50%), which is non-flammable, non-deformable, non-brittle, and can withstand high temperatures. at 7000C;

p>

3. Good sound absorption rate: When sound waves invade the fiberglass wool, a large amount of energy will be inhaled due to friction with the fibers and air pockets of different sizes. Generally speaking, the sound absorption rate can reach more than 90%, which canrmits to avoid noise interference;

4. High insulation: fiberglass can withstand high temperatures, has good mechanical properties, and has high chemical stability, making it the best insulation material;

5. High corrosion resistance: fiberglass is not afraid of strong acids and alkalis and will not reduce its functional properties for a long time;< /p>

6. Good recovery: Glass fiber contains many fixed air pockets and has excellent recovery properties. Fearing no impact or vibration, the tensile strength is more than 1.0 kg.

7. Low moisture absorption rate: The moisture absorption rate is usually close to zero.

8. Lightweight and soft: Compared with other insulation materials, fiberglass needle felt is the lightest and softest if installed on machines, it can reduce its weight and heatrge of vibration.

9. Simple construction: size can be cut according to customer.

Glass fiber monofilaments are randomly interwoven and interspersed to form a non-directional three-dimensional microporous structure with small voids and large voids. It has good sound absorption, good shock absorption and good corrosion resistance. Strength and insulation, high temperature resistance and flame retardant properties. High porosity, low gas filtration resistance, high filtration wind speed, high dust removal efficiency and at the same time bending resistance, wear resistance and dimensional stability. Fiberglass needled felt is mainly used to make AZDEL thermoplastic sheet molding compounds and polypropylene sheets. (GMT). Reinforced base material. In the past, needle feltingContinuous fiberglass tee was mainly used. However, after repeated comparisons and material selections, it is believed that when using fiberglass cut needle felt, its processing performance and ease of use are better than those used. is mainly reflected in the shortened fiberglass needle felt. When fiberglass cut needle felt and polypropylene are combined, the fluidity is better.
