Application of large acrylic (plexiglass) in new energy vehicles

Application of large acrylic (plexiglass) in new energy vehicles

Polymethyl methacrylate (PMMA), commonly known as plexiglass, is a recyclable thermoplastic engineering plastic with low density (1.15-1.19g/cm3), high mechanical strength, low melting point (130-140°C), High light rate and easy processing. The use of PMMA and its composite materials as automotive body and spare parts materials, including side triangular windows, lampshades, bumpers, etc., can effectively reduce the vehicle's own weight and achieve the purpose of reducing energy consumption and exhaust emissions.
Comparison of traditional glass and plexiglass performance:
Conventional automotive glazing generally uses inorganic glass made of a silicate-based material. The silicate compound forms a continuous network structure under high temperature conditions, and hardens and cuts after cooling to form a non-metallic material with a certain viscosity and morphology. The material has the advantages of high temperature resistance, flame retardancy and low cost. Plexiglass is formed by injection molding, extrusion or casting of polymer materials. Its chemical nature is plastic products, so its toughness, strength and weight are superior to inorganic glass.
Application of plexiglass in new energy vehicles New energy automobile window glass: Automobile windows can be divided into sandwich type and tempered type according to their structure, and can be divided into front, side, rear windshield and skylight glass according to position. In order to create a good driving vision and driving safety environment, automotive window glass should generally meet the needs of light transmission, impact resistance, weather resistance and debris. Plexiglass not only satisfies the above requirements well, but also has the function of resisting ultraviolet radiation to prevent the inside of the vehicle from being exposed to long-term exposure. On the other hand, the car's outer cover can be made by utilizing the good optical properties of the plexiglass material to protect the entire body from ultraviolet rays without affecting the driving view.
Other accessories for new energy vehicles: In addition to window glass, the application of plexiglass in new energy vehicles also includes other accessories for automobiles, such as taillights, high-gloss decorations, and automobile bumpers. Plexiglass materials are widely used in new energy automobile taillight lampshades because of their light weight, easy coloring, and aesthetics. They are widely used in new energy vehicles with high gloss decorations due to their advantages of scratch resistance, high surface gloss and high hardness. . In addition, the PMMA/ABS composite made of plexiglass and acrylonitrile-butadiene-styrene copolymer (ABS) can be used to manufacture new energy car bumpers. The composite material also has the impact resistance and resistance of ABS. It has the advantages of good temperature, good electrical properties, easy spray coating, and the advantages of plexiglass resistance to scratching, fading, and environmental protection. It is suitable as a product with high quality requirements for materials, and the cost is lower than that of magnesium alloy.
