polymer

This is a polymer material characterized by its dielectric properties at standard temperature (298 K), likely used in electrical insulation or capacitive applications where the ability to store electric charge or resist electrical breakdown is critical. Polymeric dielectrics are chosen over ceramics or glass in applications requiring flexibility, lower density, easier processing, and impact resistance, making them essential in modern electronics where space and weight constraints are significant.

Safety & Biocompatibility

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.
