1、Engineering plastic Engineering plastics 1 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

2、 quantities and tend to be used for smaller objects or low-volume applications such as mechanical parts, rather than for bulk and high-volume ends like containers and packaging. The term usually refers to thermoplastic materials rather than thermosetting ones. Examples of engineering plastics includ

3、e acrylonitrile butadiene styrene ABS, used for car bumpers , dashboard trim and Lego bricks; polycarbonates , used in motorcycle helmets ; and polyamides nylons, used for skis and ski boots . Engineering plastics have gradually replaced traditional engineering materials such as wood or metal in man

4、y applications. Besides equalling or surpassing them in weight/strength and other properties, engineering plastics are much easier to manufacture, especially in complicated shapes. The global market for engineering plastics in terms of revenue was estimated to be worth $45.2 billion in 2022 and is e

5、xpected to reach $76.8 billion by 2022.2Relevant propertieseditEach engineering plastics usually has a unique combination of properties that may make it the material of choice for some application. For example, polycarbonates are highly resistant to impact, while polyamides are highly resistant to a

6、brasion. Other properties exhibited by various grades of engineering plastics include heat resistance, mechanical strength, rigidity, chemical stability and fire safety.
