Engineering Resins

Engineering resins are a category of polymers typically used in more demanding applications than commodity resins. They typically have properties that offer higher performance such heat, chemical, and impact strength resistance which makes them well suited to replacement of metals and other materials in a wide range of electrical/electronic, automotive, aerospace, medical, and industrial applications. They include volume engineering resins ABS, PC, and nylons 6 and 66, as well as PBT, PEEK, PPO, PPS, higher-temperature nylons such as PPAs (polyphthalamides), POM, and LCPs.

FAQ: Engineering Resins

Lower mold temperatures and the associated faster cooling rates produce higher levels of internal stress in the molded part. This arises in part because of the more rapid development of the frozen layer as the material flows into the mold. This can result in flow lines that are visual evidence of impeded flow. It also produces a higher degree of retained orientation in the more rapidly cooled layers at the exterior surface.
