This post was last edited by ljtjbx on 2015-12-2 08:28. Short answer: When injecting resins such as polyamide, polyethylene, polypropylene, polyamide 66, and PBT, which of these resins must be dried? Why? Answer: Resins such as polyamides, polyamide 66, and PBT must be dried. They contain amide groups and ester groups, are prone to absorbing water, and are susceptible to hydrolysis during high-temperature processing. —————————————————— Please note: We will close this post after 24 hours, and at that time we will announce the best reply (the best assistance), as well as the answer and explanation.

To inject resins such as polyamide, polyethylene, polypropylene, polyamide 66, and PBT, which of these resins must be dried? Why? Answer: Polyamides, polyamide 66, and PBT must be dried, as they contain amide groups and ester groups that make them susceptible to absorbing water; moreover, they are prone to hydrolysis during processing at high temperatures.
