polymer_dielectric_constant_167
polymerThis is a high-dielectric-constant polymer material, likely an engineering plastic or composite polymer designed for electrical insulation and capacitive applications where elevated permittivity is required. Such polymers are used in capacitors, high-frequency circuit boards, and electrical insulation systems where conventional polymers would be inadequate; they offer the processing advantages of polymer materials (moldability, lower cost, lighter weight) while delivering dielectric performance approaching that of ceramic alternatives.

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.
