polymer_dielectric_constant_191

polymer

This is a polymer-based dielectric material, likely a thermoset or thermoplastic engineered for electrical insulation applications where controlled dielectric properties are required. The designation suggests it belongs to a family of polymers optimized for capacitive or insulating functions in electronic and electrical systems, making it suitable for applications demanding stable performance across temperature and frequency ranges.

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.
