Benefits of McLube
for Rotational Molding
Over 80% of the rotational molding industry uses one or more types of polyethylene. McLube’s consummate line of release agents for rotomolding includes tailor-made formulas for reliable release of cross-linked polyethylene (PEX, XPE, XLPE), linear low-density polyethylene (LLDPE), low-density polyethylene (LDPE), and high-density polyethylene (HDPE). We also offer rotomolding release for traditional PVC materials and new materials to the rotomolding industry, such as Nylon 6, ECTFE, polycarbonate, and polypropylene.

Common Rotomolding Challenges and How McLube Solves Them
Prerelease and Warpage
McLube’s rotomolding release agents create a thin, even film along the mold wall delicate enough to facilitate excellent surface finishes but durable enough to resist abrasion. We analyze the unique relationship that exists between every customer’s material and tooling to provide a release agent that offers enough slip for effortless separation but not so much as to cause prerelease from the mold wall.
“Swirling” is a result of excess static electricity buildup during rotational molding of dry, colored polymer resins. McLube’s line of rotational molding release agents includes anti-static coatings that reduce static buildup as resins wash over the mold surface during initial heating steps. Reduced static prevents particle separation, allowing for normal blending during the rotational molding process. Is your rotomolding process experiencing pigmentation swirling? Some rotational molders may simply be able to slow rotation during heating to prevent excess static. Contact McLube and one of our experienced Technical Representatives will help you solve color consistency issues and, if necessary, seamlessly integrate our anti-static release agent into your existing process.
Poor Surface Finish
The most important factor for excellent surface finish is the condition of the molding surface itself. McLube release agents accentuate quality tooling surfaces by forming thin, even coatings that compliment, but never diminish, the finest details. Our mold release technology also includes proprietary additives that help to protect your mold walls from dirt, rust, grime, and microscopic abrasions. Protecting your mold surfaces will extend tooling lifespan and prevent deterioration of surface finish due to material abrasion of the substrate over time. Contact McLube to learn more about how our release agents for rotomolding can improve surface finish and reduce rejection rates while saving you time and money.
