PC (polycarbonate) is a type of amorphous thermoplastic known for its high impact resistance and transparency. It also demonstrates good electrical insulation properties and moderate chemical resistance.
Available in a range of rod and plate formats, PC is commonly used in the automotive industry for the production of instrument panels, pumps, valves and more. It is also used in other sectors for the production of protective gear, medical devices, intermal mechanical parts and more.
Electroplating can be functional, decorative or corrosion-related. Many industries use the process, including the automotive sector, in which chrome-plating of steel automobile parts is common.
Bead blasting results in parts with a smooth surface with a matte texture. Used mainly for visual applications and can be followed by other surface treatments.
Painting the surface of a part improves its aesthetic appearance and can provide brand recognition to consumers. In addition, painting can have a protective effect on parts.
Polishing is the process of creating a smooth and shiny surface, either through physical rubbing of the part or by chemical interference. The process produces a surface with significant specular reflection, but in some materials is able to reduce diffuse reflection.
Engineer's Pro Tips
- PC is suitable for applications that require high hardness and transparency. Its light transmission properties are only slightly inferior to PMMA (acrylic) making it a suitable (and more lightweight) alternative to glass.
- The material is also relatively tough, allowing it to undergo chemical polishing. In high temperatures or situations with high light exposure, PC can begin to turn yellow.
