· KHS

KHS is a lightweight ceramic material belonging to the structural ceramics family, characterized by a relatively low density combined with moderate stiffness. It is employed in applications where weight reduction is critical without sacrificing rigidity, particularly in aerospace, automotive, and thermal management systems where the balance of low mass and reasonable elastic properties provides engineering value over heavier alternatives.

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.
