Brands in Performance Additives

St. Louis Group manufactures and distributes a comprehensive line of smoke suppressants that include traditional smoke suppressants, as well as low cost AOM alternatives and high-performance proprietary blends.

METABLEN™ is the trade name of modifiers, which have been developed originally by Mitsubishi chemical, a world prominent manufacture of methyl methacrylate resins. Adding a small quantity of METABLEN™ to various resins improves and increases their impact strength and processability, and further improves the characteristics, the appearance and the productivity of their final products. *METABLEN™ is provided by Mitsubishi Chemical Corporation, a member of the Mitsubishi Chemical Group.

Our FireBlend® line offers alternatives to antimony trioxide. We produce these proprietary products domestically and tailor them to flame retardant requirements.

Nonionic surfactants carry no electrical charge and are available in a variety of chemical types. The main classes are alcohol ethoxylates, alcohol ethoxylates/propoxylates, ethylene oxide-propylene oxide copolymers, castor oil ethoxylates, amine ethoxylates, fatty acid esters and their ethoxylates. They are used in a wide range of applications where they provide useful characteristics including  emulsification, solubilisation, wetting, dispersion, detergency, foaming and defoaming.

VERSALINK® are low-reactivity aromatic amines for use in polyurea or polyurea-polyurethane hybrid formulations. They can be liquid-processed at room temperature with monomeric and polymeric MDI or TDI prepolymers as well as other diisocyanates and diisocayanate prepolymers. Pot life values can be controlled and are typically in the range of 1-45 minutes, depending upon the specific VERSALINK® and isocyanate used. VERSALINK® products are specialty polymeric, non-toxic diamines that can be used as curatives and chain extenders. The range consists of varying molecular weights for use in highperformance polyurethane, polyurea and polyurea-hybrid applications. They can be processed as a liquid and incorporated with MDI and TDI/MDI prepolymers to improve final performance properties. Formulations using our VERSALINK® curatives combine the high performance of polyurea with the ease of application due to the extended pot-life and application time

Trilon® is a broad product range of high-performance and innovative complexing agents, also known as chelating agents. Trilon® chelating agents belong mainly to the class of amino carboxylates which are organic complexing agents. Chelating agents are able to prevent the deleterious impact of metal ions in technical applications. The presence of free metal ions, such as iron, copper, calcium, manganese, and further other metals, reduces the efficiency or quality of the product due to their catalytic activity, precipitation, or increased microbial growth. Trilon® chelating agents are applied in the manufacture of pulp- and paper, electronic or chemical surface treatment processes, bleaching processes in the textile/leather industry, and versatile chemical processes where metal ions can negatively impact the process.

The SILPURAN® product range comprises HTV solid and liquid silicone rubber (LSR), and room-temperature-vulcanizing grades (RTV-1 and RTV-2). These high-end silicone rubber grades meet the stringent demands of the health-care industry. All products have passed selected ISO 10993 and USP Class VI tests, and so also meet the high safety standards imposed by the health-care industry. The outstanding levels of purity needed for fulfilling the medical requirements of today and tomorrow are ensured by the WACKER CLEAN OPERATIONS program.

Evonik's SIPERNAT® precipitated silicas are well-known and used as an anti-caking agent, carrier, stabilizer, defoamer, rheology controller, microplastic replacement, and numerous others. The SIPERNAT® product range provides a specialized product solution for many challenges. Through advanced product technology, custom application development and best-in-class handling expertise, Evonik's technical team supports customers in finding the right solution to step up the performance.

Santicizer® Plasticizers offer all the benefits of high solvating plasticizers including compatibility in multiple polymer systems such as Polysulfide, PVC and Polyurethane. Because of their high efficiency, less energy is required to fuse PVC formulations. These materials are well suited for plastisol applications, but can easily be used in almost any polymer system that requires additional flexibility and softness.
