Mold release/lubricant

As thermoplastic composites become more widely adopted, an old product is finding new uses.

As thermoplastic composites become more widely adopted, an old product is finding new uses. Acra+ (AcraPlus, Phoenix, AZ, US) started in 1979 with a lubricant product called Joocy-Loob. Used on several military aircraft programs over the years, this multipurpose greaseless agent can function as a machining lubricant, mold release on flexible rubber molds, and as an anti-seize agent on cutting tools. It has been shown to be particularly effective when drilling through reinforced engineering plastics such as polyetheretherketone (PEEK), which are otherwise tough to drill. Available in a variety of weights, the lubricant is reportedly biodegradable and contains no chlorinated solvents or heavy metals.
