polymer_dielectric_constant_3
polymerThis is a polymer with a relative dielectric constant of approximately 3, placing it in the low-to-moderate dielectric range typical of many commodity and engineering polymers. Such materials are widely used in electrical insulation, circuit board substrates, and RF/microwave applications where low dielectric loss and good electrical isolation are required. The moderate dielectric constant makes this polymer suitable for applications requiring balance between electrical performance and mechanical properties, compared to higher-k ceramics or specialty polymers.

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.
