NEW! Stoner RotoFlow™ Enhanced for Crosslinked Polyethylene

Stoner RotoFlow™ Improves Quality and Production of Rotationally Molded Parts


Stoner Molding Solutions, the world’s largest manufacturer of rotational mold releases, announces the re-development of RotoFlow™ a high-efficiency mold coating for rotomolded polyolefin, nylon, and crosslinked resins.

Stoner RotoFlow™ was released in 2015 as a flow enhancer to increase detail in rotationally molded polyolefin and nylon parts. Now the NEW RotoFlow™ is available in a larger 13oz size with a new formula that is compatible with crosslinked polyethylene.

Inserts, tight radii, threads, and deep cavities are often hard-to-fill areas of rotationally molded parts. This common problem can result in weak or defective components of the molded part often leaving it unusable. Stoner RotoFlow™ increases the flow of Polyolefin, Nylon, and crosslinked resins into these difficult areas producing a fully molded part and nearly eliminating voids, pinholes, bridging, thinning, and static lines on the surface.

Stoner RotoFlow™ users have reported higher part quality, increased production efficiency, and reduced operational waste allowing them to achieve higher production goals in less time using this product.

Stoner RotoFlow™ does not contain ozone depleting substances or chlorinated solvents. Stoner RotoFlow™ is sprayed directly onto the internal mold surface and is suitable for use with most metal surfaces.

Benefits of Stoner RotoFlow™

  • Improves the quality and consistency of rotomolded Polyolefin, Nylon, and crosslinked parts.
  • Removes pinholes, voids, and blow outs.
  • Improves the appearance and operational performance of threads.
  • Increases the strength of inserts.
  • Contains no Class I or Class II ozone depleting substances.
  • Contains no CFC or HCFC propellants or solvents.
  • Contains no chlorinated solvents such as 1,1,1 trichloroethane or methylene chloride.
