Stearic acid chemical compound Britannica
WebDensity of Stearic acid: 0.9408 g/cm 3: Melting Point of Stearic acid: 69.3 °C: Boiling point of Stearic acid: 361 °C Web1 hour ago · This study investigates the effect of adding stearic acid (SA) on the thermal conductivity of polyamide 6 (PA6)/boron nitride (BN) composites. The composites were prepared by melt blending, and the mass ratio of PA6 to BN was fixed at 50:50. The results show that when the SA content is less than 5 phr, some SA is distributed at the interface … copying text from a web browser
