polymer

This is a polymer dielectric material characterized by a dielectric constant of approximately 2.24, placing it in the low-to-moderate permittivity range typical of many commodity and engineering polymers. Such materials are widely used in electrical insulation, printed circuit board substrates, and high-frequency applications where controlled dielectric properties are essential for signal integrity and electrical performance.

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.
