HeBoFill® CL-SP 035

1 of 14 products in this brand
HeBoFill® CL-SP 035* is a high-purity boron nitride powder with a very distinct crystal structure and single crystallites in the range of 35 pm. It is further characterized by its low density and intrinsic high thermal conductivity. Since large crystallites conduct heat much faster, it is predestined for use as a filler and additive in plastics. Thereby, their thermal conductivity is significantly increased, while simultaneously maintaining good electrical insulation.
