The properties of modern polymer systems can be specifically modified and adapted to special requirements through the use of fillers. Needle-shaped fillers such as Tremin 939 and platelet-shaped fillers such as Trefil Phlogopit give thermoplastics excellent values in terms of mechanical strength and heat resistance.
For thermosetting materials, the surface-treated quartz flour types of the Silbond product range have proven their worth for decades and largely determine the required mechanical, thermal and electrical characteristics of epoxy resins. Epoxy resins are used in electrical engineering in transformer construction and for the manufacture of insulators and dry transformers. If the components are exposed to strong thermal alternating stress, the use of Silbond fused silica powders prevent damage.
For elastically deformable polymers such as fluoroelastomers or silicones, high elasticity of the end product is important. Products from the blocky wollastonite Tremin 283 series are recommended for use in temperature and chemical-resistant sealing rings. They increase the tensile strength and lead to excellent dimensional stability. For tires, floor coverings, hoses, cables and similar applications, HPF offers a broad portfolio of different kaolin grades from its own deposits. They offer an increased modulus of elasticity, good tensile strength and very good colorability.
Increasing electrification is creating new challenges for masterbatch and compound manufacturers. Electrical components with high energy density require efficient dissipation of the heat generated while maintaining electrical insulation performance. Silatherm products are part of smart thermal management and are used in thermally conductive plastics.
Even for recycled plastic material, HPF The Mineral Engineers offer a smart solution for odor absorption with Rescofil.
Thanks to many years of experience in the processing of mineral fillers, HPF The Mineral Engineers also offer optimized particle distributions for higher fill levels or mineral mixtures. Silanization tailored to the customer's system leads to significantly better homogenization and even better mechanical and thermal properties.
