Engineering plastics are polymeric materials that are used in a variety of engineering applications. Engineering plastics have a wide range of physical and chemical properties that make them suitable for many different engineering applications.

Engineering plastics are used in a variety of industries, including automotive, aerospace, electronics and telecommunications. Common applications include: bearings, gears, automotive components, electrical connectors, fuel tanks, control systems and cables, pumps and valves, seals, housings and fittings.

Engineering plastics also have a variety of properties, including high temperature and chemical resistance, abrasion resistance, low friction, electrical insulation, and low smoke emissions. These properties make it an excellent choice for many engineering applications.

In terms of physical properties, engineering plastics have high strength, stiffness, and impact strength. They also have good dimensional stability, chemical and thermal resistance, low shrinkage, and excellent creep resistance.

Chemical properties of engineering plastics include excellent stability, low moisture absorption, good chemical resistance to acids and bases, good flame retardancy, and good electrical insulation.

Engineering plastics can also be recycled. They are generally categorized as thermoplastics and thermosets. Thermoplastics can be re-melted and re-used, while thermosets can be recycled but must be re-melted and re-processed to make new products.

Overall, engineering plastics are excellent materials to use in a variety of engineering applications. They have a wide range of physical and chemical properties that make them suitable for many different applications. Furthermore, engineering plastics can also be recycled, making them an environmentally friendly choice.
