polymer_dielectric_constant_107
polymerThis is a polymer dielectric material engineered for high electrical insulation performance, belonging to a family of synthetic polymers optimized for capacitive and insulating applications. It is used primarily in electrical and electronic devices where low dielectric loss and stable permittivity are critical, including power distribution equipment, high-frequency circuit boards, and energy storage systems. This material is notable for balancing dielectric reliability with processability, making it a practical choice where ceramic alternatives would be too brittle or where lower-loss polymers are uneconomical.

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.
