polymer

This is a polymer-based dielectric material engineered for high relative permittivity (dielectric constant ~5.8), making it suitable for capacitive and electrical insulation applications where compact energy storage or signal transmission is needed. The material is typically used in electronics, telecommunications, and power distribution systems where designers need to balance dielectric performance with the cost and processability advantages of polymeric substrates over ceramics. Polymer dielectrics like this offer flexibility in manufacturing, lower density than ceramic alternatives, and resistance to mechanical shock, though they generally trade off some high-temperature stability and maximum permittivity compared to specialized ceramics.

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.
