As the most advanced aviation composite in the world, SMC materials have incomparable advantages over other non-metallic materials and metal materials:


1、 SMC aviation composite material is an excellent insulating material with high performance and insulation resistance, which can prevent electric leakage, maintain good dielectric performance at high frequencies, do not reflect, do not block the transmission of microwave, and do not rust. It can be used for a long time. It is suitable for applications in crowded or narrow places to avoid the occurrence of electric shock in the box.


2、 It has good corrosion resistance and can effectively resist the corrosion of seawater, gasoline, alcohol, electrolytic salt, acetic acid, hydrochloric acid, sodium potassium compounds, urine, asphalt, various acid-base soils and acid rain. The product itself has good anti-aging performance, and the surface of the product has a protective layer with strong ultraviolet resistance. The dual protection composite product has more excellent anti-aging performance.


3、 The combination of three-dimensional network molecular structure and special reinforced fiber makes the material have good impact resistance, easy machining, convenient drilling and cutting, accurate positioning, and high tensile strength, bending and impact toughness.


4、 SMC material is a smokeless and non-toxic material. It contains no halogen, no harmful substances to human body, and does not produce harmful gases when burning. It is an environment-friendly material to meet the needs of future development.


5、 High quality flame retardant material, the flame retardant performance can reach FVO level, the smoke density level is 15, and the smoke toxicity level is quasi safety level 1 (ZA2). All materials meet the requirements of UL94 at home and abroad.


6、 The meter box body adopts the combination of plate structure, which is modular installation, suitable for handling, simple installation, and can be assembled or disassembled on site. The surface of the cabinet is cast with diamond shaped protrusions, which can prevent small advertisements from sticking.


7、 SMC is a kind of poor thermal conductor, which has low thermal deformation rate at high temperature. Its thermal insulation can reduce the impact of environmental temperature difference on the interior of the box, and can effectively reduce the occurrence of condensation and condensation in the box compared with metal materials.


8、 It is suitable for all kinds of bad weather, and the box can be used in the environment of - 50 ℃~+80 for a long time.
