1. Good electrical performance
Fiber-reinforced polyester materials used in the manufacture of electrical products have the following electrical properties:
Insulation resistance (24h immersion in water): 1.0x10 MΩ
Arc resistance: 180s
Tracking resistance index: ≥600v
Insulation protection and anti-creepage index comply with relevant DIN/VDE standards. This material not only has excellent electrical insulation, but also maintains good dielectric properties at high frequencies, is not subject to electromagnetic effects, and does not reflect electromagnetic waves. These properties are far beyond what metal materials can compare.
2. Chemical resistance
Fiber-reinforced polyester materials have good corrosion resistance characteristics such as acid, dilute alkali, salt, organic solvents, and seawater, while metal materials are not resistant to acids and seawater.
3. Lightweight and high strength
Specific strength and specific modulus are one of the indicators to measure the bearing capacity of materials. The specific modulus of fiber-reinforced polyester material is equivalent to that of steel, but its specific strength can reach 4 times that of steel.
4. Good fatigue resistance
The tensile strength of fiber-reinforced polyester is slightly better than that of steel. The fatigue limit of steel and most metal materials is 40%-50% of its tensile strength, while the fatigue limit of fiber-reinforced composite materials is generally higher than this. One value, the highest can reach 70%-80%.
5. Gap sensitivity
When the component is overloaded and a small amount of fiber breaks, the load is quickly distributed on the undamaged fiber to reach the mechanical balance again. This is incomparable to metal components.
6. Low thermal conductivity and small expansion coefficient
When there is a temperature difference, the thermal stress generated is much smaller than that of metal.
7. Excellent UV resistance and anti-aging performance
Among non-metallic materials, fiber-reinforced polyester materials have excellent anti-aging properties. The anti-aging performance test shows that the maximum aging thickness of the surface is less than 50μm in 20 years in different places of use and different climatic zones. The minimum thickness of most boxes is 5mm, which is less than 1% of the thickness of the box, so there is no obvious impact on the mechanical properties of the box. The company has adopted a special UV-resistant surface treatment process to further strengthen its aging resistance.
8. Long service life
The history of use in Europe can prove that its service life is at least 20 years; the simulated aging test shows that its service life is more than 20 years, which far exceeds that of traditional materials such as metals. Some companies that use such materials to produce pipes also claim that their pipes have a service life of 50 years.
9. Flame retardant, smokeless, non-toxic
This material is a kind of flame-retardant material, the flame retardant grade is FV0 (the highest level of non-metallic materials), the smoke generation level under high temperature burning is 15 (smoke level 1-100), and the smoke is non-toxic , The toxicity level is ZA1 (quasi-safety level).
