Electrical insulation molding compound is a plastic with resin as the matrix and glass fiber as the reinforcing material, commonly known as "FRP". It has the characteristics of light weight, high strength, good temperature resistance, corrosion resistance and excellent insulation. It is widely used in electrical appliances, machinery, instruments and meters, electronics, chemical industry, vehicles and ships and other industrial fields. Electrical insulation molding compound SMC/BMC polyester molding compound is mainly composed of resin, thickener, low shrinkage additive, filler, internal release agent, colorant, stabilizer, etc. The resin paste is prepared first, and then used to impregnate or mix with the reinforcing material to process into preform material.
As a kind of thermosetting engineering plastics specially used in the field of electrical and electronics, fiber-reinforced unsaturated polyester molding compounds for electrical use have achieved rapid development in both output and application in recent years, and have a great tendency to replace traditional thermosetting molding compounds such as phenolic and amino. In the medium and low voltage electrical appliance market, BMC products include: metering cabinet, junction cabinet, power cabinet, electrical switch, high-voltage insulation, railway insulation, explosion-proof lampshade, switch box, junction box, low-voltage instrument box, electrical components, electrical insulation, plastic encapsulated motor, etc. Among them, the application of explosion-proof electrical equipment shell is an emerging market.
1. BMC products are used in insulating parts of household appliances
For example, the market of motor coils and other packaging materials for air conditioners, washing machines, refrigerators and other products has changed the situation previously monopolized by Japanese enterprises, and the production and sales of such products have increased rapidly in the market. Many home appliance manufacturers use BMC material molded plastic to produce components such as vent trim panel, refrigerator handle, control panel and door outside watch. The main uses in small household appliances are the side plate and door handle of toast stove, the covering layer of iron bottom plate, frying pan bottom and cover, etc. Heating, ventilation and air conditioning are used in humidifier base, spiral pipe drip pan and other fields.
2. BMC products are used in meter box materials, lampshade and switch
SMC/BMC is still a blank in the market of high-voltage electrical products. With the continuous improvement of the working voltage of the power system, the requirements for the comprehensive performance indicators of high-voltage insulating materials are more stringent, and the electric breakdown strength is also required to go up to a higher level on the original basis. Through the optimization of SMC/BMC electrical formula, the problems such as large internal defects of existing products and large electrical strength dispersion coefficient caused by uneven materials are solved, so that the application field of electrical BMC material is expanded to high-voltage insulation materials, which meets the growing demand of the electrical industry for SMC/BMC.
It is believed that with the excellent insulation performance, relatively low dielectric constant and the advantages of light weight, high strength, temperature resistance and corrosion resistance of BMC material, it is bound to have a broader development space.
As a leading BMC/SMC molds and BMC/SMC molded products manufacturer in China, Aobang Technology Company Limited provide various products, BMC/SMC molds including but not limited to motor mold, auto parts mold, SMC cable bracket moulding and frame molding; BMC/SMC molded products including but not limited to BMC/SMC motor, SMC auto parts. The high-composite precision molds produced by Waiwai Tree have the characteristics of low energy consumption; our SMC and BMC molds have no waste, and there is no need to clear the inner cavity. Having only a small temperature difference, our SMC/BMC composites have stable mold temperature, good appearance, and high efficiency. Thus, they are now widely used in new energy vehicles, high-speed rail, and electric motors. Feel free to contact us if you have any related need!
