polymer_dielectric_constant_23
polymerThis is a polymer-based dielectric material engineered for high electrical insulation performance, characterized by a dielectric constant around 2.3—significantly higher than standard polymers like polyethylene but lower than ceramic alternatives. It is used in applications requiring controlled electrical properties, such as capacitors, printed circuit board (PCB) substrates, and signal transmission lines, where the balance between insulation strength and frequency response is critical. Compared to traditional thermoset resins or ceramics, this polymer offers easier processing, better mechanical flexibility, and cost advantages while maintaining the electrical isolation needed in modern electronics.

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.
