polymer

This is a polymer-based dielectric material engineered to provide a dielectric constant around 10.3, positioning it in the high-permittivity polymer category for applications requiring enhanced capacitive performance without the brittleness or processing limitations of ceramic dielectrics. It is used in electronic components, capacitors, and insulation systems where moderate-to-high electrical permittivity is needed alongside the mechanical flexibility, machinability, and cost advantages of polymeric substrates; engineers select this type of material when thermal stability, dimensional tolerance, and ease of fabrication outweigh the superior dielectric performance of ceramics, or when hybrid polymer-ceramic composites are impractical.

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.
