The melting point of glass fiber is 680 ° C, the boiling point is 1000 ° C, the density is 2.4 ～ 2.7g/cm³. The tensile strength is 6.3 to 6.9g/d at the standard state, and the moisture is 5.4 ～ 5.8g/d.
Enhanced rigidity and hardness: The increase in glass fiber can increase the strength and rigidity of the plastic, but the toughness of the same plastic will decrease.
Good toughness, not easy to deform, good impact resistance: During the process of glass fiber application, sometimes deformation due to stretching or gravity, but because of its good toughness, it will return to its original when the force within the ending range, and use it. Use it. Use it. Use it. Use it. Use it. efficient.
Good heat resistance: Glass fiber is an inorganic fiber with a very small thermal conductivity, which will not cause burning and reconcile heat resistance. In the production materials that are often used as fire prevention tools, many hidden safety hazards can be reduced.
Humidity: The water absorption of glass fiber is 1/20 ~ 1/10 of natural and synthetic fibers. The water absorption rate is related to the glass component. The water -free fiber water absorption is the smallest and the high -alkali fiber water absorption is the largest.
Crisability: The brittleness of glass fibers is higher than that of other fibers, not tolerated and easy to break. But when the diameter of the fiber is less than 3.8 μm, the fiber and its products have good softness.
Good corrosion resistance: the chemical stability of glass fiber depends on its chemical composition, medium nature, temperature and pressure. Glass fiber has good tolerance on corrosive chemicals such as acid and alkali, is almost not affected by organic solvents, and stabilizes most of the inorganic compounds.
