Polycarbonate (PC) is a durable plastic that maintains its toughness, dimensional stability, and excellent impact resistance in a
wide range of temperatures. Typically, the material maintains its electrical insulating properties and resists creep in extreme
temperatures and humid environments. Plastic refers to a group of synthetic or semi-synthetic materials that have been engineered
to achieve specific properties. The most notable characteristics of plastics are its low weight, machinability, corrosion
resistance, and typically good thermal and electrical insulating properties. Certain plastic grades also offer optical
transparency similar to glass, low-friction or self-lubricating surfaces, and exceptional impact resistance. Depending on their
properties, certain plastic grades can be used as alternatives to metal, glass, and ceramic. Unlike metal, plastic may experience
creep, which is deformation caused by longtime exposure to a constant load. Tensile strength, used to indicate the material’s
overall strength, is the peak stress it can withstand before it breaks. Corrosion resistance describes the material's ability to
prevent deterioration caused by atmosphere, moisture, or other medium. Wear resistance indicates the ability to prevent surface
damage caused by contact with other surfaces. Toughness describes the material's ability to absorb energy before breaking, while
hardness (commonly measured as indentation hardness) describes its resistance to permanent surface deformation. Impact resistance
is the measure of a material’s ability to absorb a shock of energy before breaking.
