ReleaSys™ RM | Rotational Molding Release Agent
Innovative Chemistry; Exceptional Longevity, Ease of Release, and Surface Quality
Miller-Stephenson’s ReleaSys™ RM Rotational molding release agent combines over 50 years of release agent expertise and thermoplastic molding experience. Rotational Molding is a dynamic industry which utilizes an ever-widening variety of thermoplastic resins. In response to this evolution, Miller-Stephenson has developed a robust portfolio of specialized release agents. These formulations are tailored to meet rotational molding efficiency challenges such as shorter, hotter cycles, tighter tolerances, and complex molds. ReleaSys RM is heat stable to 600°F, cures rapidly (even at room temperature), and transfers no mold release to the part. These exceptional performance characteristics are due to this rotational molding release agent’s usage of a proprietary formulation which tenaciously binds to the mold surface, providing a high-slip, robust barrier that is extremely abrasion resistance. The low surface energy of our coating, enhances flow of the melting resin, minimizing surface defects and decreasing cycle times. Benefits of utilizing ReleaSys RM Rotational Molding release agent are the following:
- Multiple releases from a single application
- No Transfer
- Lower Scrap
- Reduced Pigment Build-up; Better Cosmetics
- Increased Productivity through reduced downtime
- No VOC, no Odor; Waterbased formulation
Producing a high quality, dimensionally-controlled rotomolded part would be easy if all parts were the same shape and size, but they are not. For example, a fuel cell for a marine application usually needs to be molded in a shape that will allow it to fit into a very irregular and tight space envelope. A Silo-style storage tank, on the other hand, is a large and regular in shape. The demands placed on the release agent for these two applications are very different. The marine gas tank will usually require a release agent that provides excellent resin flow during the molding process and maximum assistance when releasing from the mold. The large water storage-tank requires similar flow assistance but a modified slip-level to prevent pre-release or other defects. Thanks to Miller-Stephenson’s extensive expertise in the rotomolding industry we understand the problems rotomolders experience and have developed specialized rotational molding release agents to meet these specific requirements.
100% Water-based, Self-Levelling, Zero-VOC – a potent combination
ReleaSys™ RM rotational molding release products should be applied via any method which delivery fine atomization or via a microfiber cloth. Ideally the mold surface would be between 20°C (68°F) and 205°C (400°F). Spray application is recommended, although brushing or wiping may also be used. Optimum multiple release performance is obtained by applying to molds preheated above 60°C (140°F). The ease of release, number of releases/application and surface finish will depend on application technique, mold temperature and number of coats applied. ReleaSys RM has been optimized for use on the following plastics:
- LLDPE, LDPE, MDPE, HDPE, XLPE,
- Polypropylene (PP)
- Nylon / Polyamide
