Characteristics of plastics

Light weight, high strength. Plastic light, the density of plastic is between 0.9 to 2.3 grams/cubic centimeter, only about 1/2 of 1/8 ~1/4 of steel, aluminum, and the lower density foam, approximately between 0.01 to 0.5 g/cm³. Calculation of strength per unit mass than strength, reinforced plastic strength of close to or even more than steel. For example, steel alloys, the tensile strength per unit mass is 160 MPA, with glass-fiber-reinforced plastic can reach 170 to 400 MPA.

Excellent electrical insulation properties. Almost all plastics have excellent electrical insulating properties, such as minimum dielectric loss and excellent arc characteristics, the performance is comparable to ceramic.
