First, the mechanical properties: Acrylic has a good comprehensive mechanical properties, in the forefront of general plastics, whether it is tensile, bending, compression and other strength properties are higher than polyolefin, PS and other similar products, but its impact toughness Poor, that is to say it is more sensitive, easy to crack under stress, is a hard and brittle plastic, but only relative to itself, this performance is flat compared to similar products. However, the hardness of the acrylic surface is relatively low, it is easy to scratch, and the strength decreases with the increase of the action time. Therefore, consumers are required to use more care when using it.
Second, electrical properties: Acrylic contains a polar methyl ester group, so its own polarity is not too large, with good dielectric and electrical insulation properties. In the high frequency range, the acrylic power decreases with increasing frequency and is suitable for use as an outdoor appliance. It has excellent arc resistance, and even the surface of the acrylic under the high intensity of the arc does not produce carbonized conductive paths and arc track phenomena due to its large surface resistance.
Third, other properties: Acrylic light transmittance is among the best in all types of light transmissive products, can pass most of the ultraviolet light and infrared light, excellent coloring performance, wide overall color range, and due to its electricity It has excellent performance, so it will not cause discoloration and fading under the action of heat, and the surface gloss is good, and it can be made into an ornament of a luminescent pattern. In addition, acrylic has excellent weathering resistance, although its mechanical properties and optical properties decrease slightly with aging time, but its performance is more advantageous in terms of overall products.
