SMC is the abbreviation of Sheet molding compound, SMC composite material, SMC molding compound or sheet molding compound (commonly known as FRP material). The main raw materials are composed of SMC special yarn, unsaturated resin, low shrinkage additives, fillers and various additives. SMC has the advantages of superior electrical performance, corrosion resistance, light weight, easy and flexible engineering design, and its mechanical performance can be comparable to some metal materials, so it is widely used in electrical, electronic, vehicle, construction, chemical, aviation and other industries in. As the most advanced and popularized electrical equipment housing manufacturing material in the world, SMC composite material has incomparable advantages with other non-metallic materials and metal materials:
1. Excellent electrical insulation performance: SMC is an excellent insulation material; it has high-performance insulation resistance, prevents leakage, and can maintain good dielectric properties at high frequencies. It does not reflect or block the propagation of microwaves. Rust can be used for a long time. 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.
2. High-quality flame-retardant materials: The flame-retardant performance of SMC composite materials can reach FVO level, and the smoke toxicity level is quasi-safe level. Our company’s materials can meet UL94 requirements at home and abroad.
3. Excellent corrosion resistance: SMC composite materials 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 UV resistance. The dual-protection product has higher anti-aging performance.
4. Excellent mechanical properties: SMC composite material is mainly composed of excellent insulating material dimensional network molecular structure and special reinforcing fiber, so that the material has good impact resistance, easy to machine, easy to drill and cut, and accurate positioning , Has high tensile strength, bending and impact toughness.
5. Environmental protection and non-toxic materials: SMC composite material is a kind of halogen-free and no harmful substances to the human body. It is a new type of environmentally friendly material to meet the needs of future green development.
6. Low thermal conductivity and small expansion coefficient: SMC composite material is a kind of high temperature resistance and low thermal deformation rate, and its thermal insulation can reduce the influence of environmental temperature difference on the inside of the box. Compared with metal materials, it can effectively reduce condensation inside the box. happened.
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 degree of the surface is small in different places of use and different climatic zones, so it has no obvious impact on the mechanical properties of the cabinet. Our company has adopted a special UV-resistant surface treatment process to further strengthen its aging resistance.
