TraSys 4000 RotoFlow is a mold coating that facilitates the flow of polyolefin (including Cross-Linked Polyethylene) and nylon resin into hard-to-fill areas of rotational molds. RotoFlow helps fill in voids around inserts, tight radii, threads, and deep cavities. RotoFlow prevents pinholes on the surface of rotomolded parts. It reduces bridging, thinning, blowholes, and static lines.

Bearing the NSF® Mark assures Stoner Molding customers that RotoFlow® has been tested and approved for use in food-grade rotationally molded plastics.
