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 ‘commodity’ plastics. The term usually refers to thermoplastic materials rather than thermosetting ones.
Examples of engineering plastics include:
Acrylonitrile butadiene styrene (ABS)
Polybutylene terephthalate (PBT)
Polyethylene terephthalate (PET)
Polyphenylene oxide (PPO)
