- Features and Benefits
- BORATHERM™ SA grades are used in formulations (thermosets and thermoplastics) for applications where excellent heat dissipation is critical to the operating and longevity of the device/component, e.g. packaging of battery-packs, plastic parts for housing of electromotors and charging units for EV’s.
- To guarantee a consistent product quality of BORATHERM™ SA grades the chemical composition of the raw material and product particle size of the final products are closely monitored and kept within a narrow variation.
