Engineering plastics are a group of plastic materials that have better mechanical and/or thermal properties than the more widely used commodity plastics (such as polystyrene, PVC, polypropylene and polyethylene).
Being more expensive, engineering plastics are produced in lower quantities and tend to be used for smaller objects or low volume applications (such as mechanical parts), than for large and high volume parts (such as containers and packaging).
This term usually refers to a thermoplastic material rather than a thermosetting one. Examples of engineering plastics include acrylonitrile butadiene styrene (ABS), used for car bumpers, dashboard trim and Lego bricks; polycarbonate, used in motorcycle helmets; and polyamide (nylon), used for ski boots and ski boots.
Engineering plastics are gradually replacing traditional engineering materials such as wood or metal in many applications. In addition to matching or exceeding weight/strength and other properties, engineering plastics are much easier to fabricate, especially in complex forms.
The global engineering plastics market is worth $ 57.2 billion in 2014 and is expected to reach $ 91.78 billion by 2020 at a compound annual growth rate of 8.2%.

Relevant properties
Each engineering plastic typically has a combination of unique properties that can make it the material of choice for multiple applications. For example, polycarbonates are very resistant to impact, while polyamides are highly resistant to abrasion. Other properties are represented by various grades of engineering plastics including heat resistance, mechanical strength, stiffness, chemical stability, self lubrication (specifically used in gear & amp; manufacture) and fire safety.
