Engineering plastics are a group of plastic materials that exhibit superior mechanical and thermal properties in a wide range of conditions over and above more commonly used commdity plastics. The term usually refers to thermoplastic materials rather than thermosetting ones.

Examples of engineering plastics include:

Acrylonitrile butadiene styrene (ABS)
Polycarbonates (PC)
Polyamides (PA)
Polybutylene terephthalate (PBT)
Polyethylene terephthalate (PET)
Polyphenylene oxide (PPO)
Polysulphone (PSU)
Polyetherketone (PEK)
Polyetheretherketone (PEEK)
Polyimides

Engineering plastics
Engineering thermoplastics are sold in much lower quantities and are thus more expensive per unit weight. Despite this, they are widely used in everyday products. For example ABS is used to manufacture car bumpers and dashboard trim, polycarbonate is used in motorcycle helmets and polyamides (nylons) are used for skis and ski boots.
Typically, an engineering plastic is chosen for its range of enhanced physical properties e.g. polycarbonate is highly impact resistant and polyamides are highly resistant to abrasion. In these types of applications, designers are looking for plastics that can replace traditional engineering materials such as wood or metal. The advantage gained is the inherent ¡®formability¡¯ (ease of manufacture) of plastics as opposed to metal-working or fabrication.

Other properties exhibited by various grades of engineering plastics include high heat resistance, mechanical strength, rigidity, chemical stability and flame retardency.
