工程塑料是指强度、模量和 耐磨损 耐疲劳性 韧性等参数较高，主要应用在工业领域作机械结构材料的塑料，某些高端消费产品为提高品质，也会使用工程塑料，如ABS。

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), rather than for bulk and high-volume ends (like containers and packaging).
