Difference between glass fiber surface felt and continuous felt

Glass fiber felt is a sheet-shaped product made of continuous precursor or chopped precursor which is non directionally combined by chemical binder or mechanical action. It is divided into different types. Next, Yiying glass fiber briefly introduces the difference between glass fiber surface felt and continuous felt.

Glass fiber surface felt is generally used to improve the surface effect and reduce the influence of cloth texture on the surface.

Application field of surface felt:

1. Electronic field

Decorating the electronic device area can obtain electromagnetic or RF shielding; Multiple effects of electrostatic protection, and can be used for satellite reflector.

2. Chemical containers and filtration

It is suitable for pipes, tanks, tanks and seawater corrosion resistant to various concentrated acids and alkalis. It can also be used to filter corrosive gases or liquids.

Continuous felt is generally used as diversion material, and short cut felt will be used a little in the hand pasting process to increase the interlayer force, which is less used.

characteristic:

1. The product is tear resistant. As the continuous felt precursor is continuously looped, isotropic and has high strength (about 1-1.5 times the strength of the chopped felt), it is tear resistant.

2. Product surface finish, high product surface finish, can be used for decorative surface.

3. The product designability can be applied to different product requirements and forming processes, such as pultrusion, RTM, vacuum casting and molding, through the change of felt layer and tightness and the difference of adhesive.

4. Easy to cut, good flexibility and film covering, easy to form, and can adapt to more complex molds.
