Boratherm

Boratherm™ GA 6 is submicron ground alumina produced by the calcination of carefully selected synthetic aluminum hydroxide (ATH). Boratherm™ GA grades are often used in combination with Boratherm™ SA and Boratherm™ SG grades in order to enhance a formulation’s particle packing and flow properties, resulting in improved thermal conductivity and stability (filler-settling). To guarantee a consistent product quality of the Boratherm™ GA grades, the chemical composition of the raw materials and the product particle size of the final products are closely monitored and kept within a narrow variation.

Boratherm™ H5 F13.0 is produced from a carefully selected, naturally occurring, platy, sedimentary mineral that predominantly consists of partially hydrated magnesium-calcium carbonate. The mineral’s platy particle shape and sub-micron particle size make Boratherm™ H5 products an effective rheology modifier in aqueous suspensions and other fluids. Boratherm™ H5 F13.0 is stearic acid surface-treated Boratherm™ H5 to render the surface hydrophobic. To guarantee a consistent product quality for the Boratherm™ H5 grades, the chemical composition of the raw materials, the product particle size of the final products, and the treatment process (in the case of the Boratherm™ H5 F13.0) are closely monitored and kept within a narrow variation.

Boratherm™ SA 0020 spherical alumina particles are made from a special fusion process using high-quality ground alumina material. Boratherm™ SA grades are used in various applications because of their high thermal conductivity, heat resistance, and low thermal expansion. Due to the sphericity of the particles and the possibility to combine grades, one can obtain very high packing densities, resulting in formulations with excellent thermal conduction while maintaining low viscosity and easy application.

Boratherm™ SG 200LVS is a blended product produced from carefully selected synthetic aluminum hydroxide (ATH). This product is used in applications where heat-dissipation and fire-retardancy are critical properties, e.g., in thermal interface materials (including electronic vehicle battery heat management), casting resins for power transformers, and potting and encapsulating materials in electric and electronic applications. The particle size distribution of the Boratherm™ SG 200LVS is already optimized, so blends with other finer or coarser aluminum-containing grades are no longer needed to obtain the optimum packing density, resulting in the right balance between flow and thermal conductivity.

Boratherm™ SG150 E is produced from carefully selected synthetic aluminum hydroxide (ATH). Boratherm™ SG-E grades are used in various applications because of their high thermal conductivity, flame retardancy, smoke suppression, and low viscosity. Combining these grades with finer products (ATH or Al2O3-based) makes it possible to obtain a high packing density, resulting in excellent thermal conductivity. Boratherm™ SG is perfectly suited for formulations needing good flowability. It is specially designed to offer an ultra-low surface area and large particle sizes.

Boratherm™ SG25/10 is produced from carefully selected synthetic aluminum hydroxide (ATH). Boratherm™ SG25/10 is a micronized functional filler used in formulations for applications in which thermal conductivity is an important property. It has very good chemical inertness (for outdoor and chemical applications). The standardized quality of Boratherm™ SG25/10 is guaranteed by means of an ISO 9001-certified quality management plan. The chemical composition of the raw material and the finished product is closely monitored, and the particle size is kept within a narrow variation. Boratherm™ SG25/10 is perfectly suited for formulations needing good flowability. It is specially designed to offer an ultra-low surface area and large particle sizes.

Boratherm™ GA6 S21.5 is submicron ground alumina produced by the calcination of carefully selected synthetic aluminum hydroxide (ATH). Boratherm™ GA grades are often used in combination with Boratherm™ SA and Boratherm™ SG grades in order to enhance a formulation’s particle packing and flow properties, resulting in improved thermal conductivity and stability (filler settling). Boratherm™ GA6 S21.5 is the surface-modified (1.5 % w/w coated) version of Boratherm™ GA6, a submicron ground alumina tailored to improve the stability of thermally conductive uncured polymeric composites. Changes in type of treatment and loading level are possible to meet your specific requirements. To guarantee a consistent product quality for the Boratherm™ GA grades, the chemical composition of the raw materials, the product particle size of the final products, and the treatment process (in the case of the Boratherm™ GA6 S21.5) are closely monitored and kept within a narrow variation.
