Boron Nitride Grease CAS 10043-11-5, h-BN Silicone Synthetic Oil for High-Temp Thermal Insulating Electronic Precision
This boron nitride grease is a high‑performance specialty electronic lubricating grease. It adopts silicone synthetic oil as base fluid, filled with finely ground hexagonal boron nitride (h‑BN) powder and stabilized anti‑oxidant additives. Hexagonal boron nitride delivers excellent thermal‑insulating property together with low‑friction lubricating performance. The grease remains stable under high‑temperature operating conditions, offering thermal‑insulating and anti‑wear lubrication for precisio
Product DetailsBoron Nitride Grease CAS 10043‑11‑5, h‑BN Silicone Synthetic Oil for High‑Temp Thermal Insulating Electronic PrecisionThis boron nitride grease is compounded with silicone synthetic base fluid, special thickener, uniformly dispersed fine hexagonal boron nitride (h‑BN) powder and anti‑oxidant stabilizing additives. The h‑BN filler features low electrical conductivity and outstanding thermal stability. It does not soften or decompose rapidly at high service temperature. The silicone synthetic base oil possesses favorable high‑temperature resistance and low‑temperature flexibility, maintaining consistent grease consistency across a wide working‑temperature range. The solid h‑BN particles stay well suspended inside the grease matrix without sedimentation during static storage.
When applied onto sliding and mating surfaces of precision electronic assemblies, the grease forms a continuous, adherent composite lubricating film. This film provides effective thermal insulation between adjacent electronic parts, reduces frictional wear during tiny reciprocating or rotary movement of precision mechanisms, and prevents local thermal runaway risk induced by direct metal‑to‑metal contact under high‑temperature working conditions. It avoids short‑circuit hazards thanks to its insulating characteristics.
Under repeated micro‑vibration and mechanical shearing inside electronic equipment, the grease exhibits reliable shear stability and resists oil bleeding. Anti‑oxidant additives retard thermal‑oxidative ageing of silicone base fluid, slowing performance degradation during long‑term continuous operation. The formulation shows good compatibility with most common engineering plastics and elastomers used within electronic devices.
It is suitable for assembly greasing of precision electronic sliding components, high‑temperature movable connectors and miniature mechanical modules inside power electronic devices. Coating thickness requires precise control. Excessively thick grease layers may impede local heat dissipation where heat transfer is required; insufficient coating cannot deliver complete thermal‑insulating protection and adequate anti‑wear lubrication for moving interfaces.
Do not mix this h‑BN boron nitride grease with hydrocarbon‑based grease, conductive silicone grease or lithium‑based greases. Incompatible blending will destroy the stable suspension of boron nitride filler, cause inconsistent insulating performance and degrade high‑temperature lubricating capacity. Store in tightly sealed original containers inside cool, dry indoor warehouse. Avoid prolonged high‑temperature storage to preserve thermal‑insulating and anti‑wear lubricating performance for high‑temperature precision electronic assemblies.
