polymer

This is a polymer material characterized by its dielectric constant measured at 295 K (room temperature), belonging to the broader class of electrical insulating polymers. While the specific polymer composition is not detailed here, such materials are engineered to control electrical properties and are critical in applications requiring controlled permittivity and low loss characteristics. Polymers with well-defined dielectric constants are essential in electronics, power systems, and telecommunications where precise electromagnetic behavior is needed to prevent signal distortion, manage capacitance, or provide reliable insulation.

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.
