polymer

This is a high-permittivity polymer dielectric material engineered to achieve a dielectric constant around 21, significantly higher than typical unfilled polymers. Such materials are typically achieved through ceramic filler incorporation (alumina, barium titanate, or similar) into a polymer matrix, combining the processability of plastics with enhanced electrical properties. Industries including electronics, telecommunications, and power distribution leverage these materials in applications requiring compact capacitive devices, high-voltage insulation systems, and energy storage components where the combination of dielectric performance and polymer workability provides advantages over traditional ceramic alternatives.

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.
