Chem-Trend is a leading global manufacturer of process chemical specialties with a main focus on high-end mould release agents. Chem-Trend develops mould release agents used for the production of moulded components made of composites, rubber, thermoplastics, or polyurethane, die lubricants for application in the die casting industry, as well as purging compounds and inside and outside tyre paints. In addition, Chem-Trend manufactures specialized ancillary products, such as mould maintenance products, mould cleaners and mould sealers for the individual industries. Chem-Trend celebrated its 50th anniversary in 2010.
In 2016, Chem-Trend acquired the Ultra Purge™ business from Moulds Plus International to widen its product portfolio for thermoplastics processing operations.
Ultra Purge ™ products are ready-to-use or concentrated chemical, mechanical or hybrid chemical/mechanical purging compounds designed to increase productivity during color and material changes, startups and carbon removal procedures. Ultra Purge™ products are recommended by major machine and colorant producers as the most cost-effective and efficient solution for cleaning plastic processing machines. Contaminants are safely ejected without harming the screw, barrel or hot runner. Expanding agents in most Ultra Purge ™ products allow the material to clean even the hardest-to-reach areas inside your machines. Ultra Purge ™ is effective for color changes, material changes and the removal of black specks. Ultra Purge™ works at the processing temperature of the production material.
Lusin® Protect G 31 F is an anti- corrosion protectant developed specifically for use in the packaging industry and is applicable for food grade applications where incidental food contact is possible.
The new product is a dry film which provides significant benefit over typical oil-based rust inhibitors. The dry film does not creep between mold plates, slides and core adjustments and can be easily removed from the mold cavity by the simple process of part molding, allowing for time and labor savings. Additionally, unlike typical oil-based rust-inhibitors the new product does not produce “oil marks” on transparent and optical parts.
During the rotomolding process, ground thermoplastic resins are tumbled against the inner surface of a hot rotating moulding tool, where the powder will coat the mould surface and fuse together. In this way, seamless hollow components can be manufactured. Irregular shaped components in particular often comprise areas such as tight corners, narrow cross-sections or inserts near to side walls, which the moulding resin will have difficulties to flow into and fully coat the surface or fuse together. This can for example lead to surface “pinholes”.
With the Flow Promoter, Chem-Trend has developed a solution which helps the material to reach and adhere to difficult areas, thus ensuring that the moulded part takes on an even, blemish-free surface.
