Many polymers degrade under influence of heat, light and oxygen, i.e. by chemical reactions the polymer chain is disrupting. Therefore the mechanical properties and appearance changes partially substantial. By addition of specificially suitable stabilizers this can be inhibit over a long period of time. In this connection one differs between processing stabilizers, which counteract against polymer degradation in the melt stage (compounding, extrusion, injection moulding), long-term heat stabilizers, which counteract against polymer degradation under elevated service temperatures (60 - 130°C) of the finished parts, high temperature stabilizers, which are active up to 180°C, as well as UV-stabilizers as efficient protection of the finished parts against polymer degradation through UV-radiation. Combinations of different types of stabilizers result in additional synergistic effects.
As a zinc producer with a long tradition BrüggemannChemical is able to offer you a broad variety of products for several applications. Direct and indirect zinc oxides are so called thermal zinc oxides which have a broad spectrum of applications. They are utilized for instance in the rubber-, the ceramics/glass-, the pharmaceutical/cosmetic- and the paint/coatings industry. Active zinc oxide and zinc carbonate are produced wet process by precipitation from a zinc containing solution. BrüggemannChemical manufactures products with a specific surface area of up to 100m²/g by a careful drying procedure. Active zinc oxides are mainly utilized in the rubber industry. In cooperation with our customers, BrüggemannChemical has recently developed new application fields in the area of personal care and household. Due to the achieved extremely high specific surface areas, the active zinc products are used for absorption and adsorption materials for instance for Denox- and desulfurizing catalysts and among others for the production of special zinc products for the chemical industry.
BrüggemannChemical is the world's leading supplier of high-performance additives in the area of Polyamides and Polyesters. BrüggemannChemical cooperates closely with customers providing technical support with a team of experienced experts supported by a sophisticated technical and R&D center. Product innovations and product improvements are constantly targeted to market demands. BrüggemannChemical´s additive specialities enable customers to meet high technical requirements in a wide range of applications: Injection molding, extrusion, fibers, monofilaments, packaging films etc. In addition, the AP-NYLON® products for nylon casting comprise a series of additives and the monomer AP-Caprolactam suited for anionic polymerization. With the range of NYRIM® additives customers produce specific nylon block copolymers which exhibit inherent excellent impact resistance down to -30°C. The impact performance can be selected from medium impact to even unbreakability.
Reducing Agents and active Zinc Derivatives
BrüggemannChemical is the leading manufacturer of sulphur-based reducing agents and the sole remaining Sodium-Formaldehyde-Sulfoxylate producer in the western world. As the only company globally with R&D in this area BrüggemannChemical is thus able to offer new product developments, like the unique Bruggolite®FF6M. A reducing agent with significantly better performance and no formaldehyde, which is perfect for post polymerization with the goal of low residual monomer and VOC levels. The range of Zinc derivatives comprises direct Zinc Oxides (American-Process), indirect Zinc Oxides (French-Process) as well as active Zinc Oxides and Zinc Carbonates. The applications of these products cover areas from rubber and paints to cosmetic, personal care and pharmaceuticals.
