Flow Promoter for Rotational Molding

REQUEST FREE CONSULTATION

Poor surface part appearance caused by pinholes and other blemishes can form during the early stages of the rotational molding process. This is caused by tumbling resins being unable to reach and remain in the places where they are most needed.

A solution that can alleviate this common issue is the Chem-Trend Flow Promoter, which is designed to help attract molding resin to these potentially “starved” areas, helping to ensure that your molded part takes on an even, blemish-free surface. While Flow Promoter does not replace the release agent, it is an ideal complement for rotomolders who want to improve the look and quality of finished parts.

Benefits for rotational molding:

Most effective surface improvement: Better coverage, with no visible fouling or buildup on the mold, is provided by the Flow Promoter.

Blemish-free parts with minimal pinholing: Complete powder coverage of mold surfaces, even in the most difficult areas is promoted. Plus, reliable forming thanks to faster drying time.

Excellent part replication: Consistency is created by better molding of threads, insert encapsulation, complete edges, and letter formation.
