polymer_dielectric_constant_171
polymerThis is a polymer-based dielectric material with a dielectric constant of approximately 1.71, likely a non-polar organic polymer such as polyethylene, polypropylene, or a similar hydrocarbon-based polymer. Materials in this family are chosen for electrical insulation applications where low permittivity and minimal signal loss are critical. Common industrial uses include cable insulation, printed circuit board substrates, capacitor films, and microwave-transparent housings; engineers select these materials when low dielectric loss, good electrical breakdown resistance, and cost-effectiveness are priorities.

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.
