Boratherm™ SG200 E
- CAS Number
- 21645-51-2
- Chemical Name
- Alumina Trihydrate (ATH)
- Chemical Family
- Aluminum Compounds
Boratherm™ SG200 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.

- Benefits and Features
The amount of magnetic particles is controlled at a low level making the materials ideally suitable for electronic applications.; BORATHERM™ SG-E grades are also used as flame-retardants. The mechanism of flame-retardancy is mainly based on the endothermic decomposition of the aluminum hydroxide (heat-sink effect) while simultaneously releasing water vapor. This reaction starts at about 200°C.; BORATHERM™ SG-E grades are also used in applications where heat-dissipation and fire-retardancy are both critical properties, e.g. in Thermal Interface Materials (including Electronic Vehicle Battery heat management), casting resins for power transformers and potting & encapsulating materials in electric and electronic applications.
