· JVASP-63760· UBN

UBN is an advanced ceramic material belonging to the boron nitride family, engineered for extreme-environment applications requiring exceptional hardness and thermal stability. It is primarily employed in high-temperature aerospace components, semiconductor processing equipment, and cutting tool applications where conventional ceramics fail. Engineers select UBN for applications demanding resistance to thermal shock, chemical inertness, and performance in abrasive or corrosive environments where cost-effective alternatives cannot withstand operational demands.

Regulatory Screening

Environmental

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
