Fiberglass sleeving high temperature: mainly used for electrical insulation materials, FSG soft, self-extinguishing silicone glass fiber sleeve. FSG series soft self-extinguishing silicone resin glass fiber sleeving is woven from alkali-free glass fiber yarn, and then treated with high temperature and coated with silicone copolymer resin.
The fiberglass sleeving high temperature has certain dielectric properties, good self-extinguishing and superior flexibility, and is widely used for H-class motor insulation; in-machine wiring clusters for household appliances and electronic instruments such as energy-saving lamps, refrigerators, air conditioners, bathroom heaters, TVs Wait for insulation protection.
Fiberglass sleeving high temperature is woven with alkali-free glass fiber, coated with special polyurethane resin and baked. This coating is well combined with glass fiber and can maintain the dielectric strength after aging. The glass fiber insulation sleeve has reliable electrical properties, good heat resistance, excellent flexibility, and resistance to acids, alkalis, and organic solvents. It is used for wiring insulation of Class F (155 ° C) motors, electrical appliances, and various household appliances. With mechanical protection.
Fiberglass sleeving high temperature use glass fibers, so the use of glass fiber insulation sleeves also depends on the role of glass fibers. What role does glass fiber have?
The role of glass fiber:
1. Enhance the rigidity and hardness. The increase of glass fiber can improve the strength and rigidity of plastic, but the toughness of the same plastic will decrease.
2. Improve the heat resistance and heat distortion temperature; take nylon as an example, the nylon with glass fiber added, the heat distortion temperature is increased by at least more than two times, the general glass fiber reinforced nylon temperature resistance can reach more than 220 degrees
3. Improve dimensional stability and reduce shrinkage;
4. Reduce warpage;
5. Reduce creep;
6. The flame retardant performance will interfere with the flame retardant system due to the candle wick effect and affect the flame retardant effect;
7. Decrease the gloss of the surface;
8. Increase hygroscopicity;
9. Glass fiber treatment: The length of glass fiber directly affects the brittleness of the material. If the glass fiber is not handled well, the short fiber will reduce the impact strength, and the long fiber treatment will increase the impact strength. To make the brittleness of the material not to drop greatly, we must choose a certain length of glass fiber.
