polymer

This is a polymer-based dielectric material characterized by its electrical insulation properties, suitable for applications requiring controlled permittivity. The material is used in electrical and electronic components where dielectric performance is critical, such as capacitors, insulators, and high-frequency circuit boards. Its synthetic polymer backbone makes it a cost-effective alternative to ceramic dielectrics in applications where moderate temperature performance and processability are prioritized over extreme thermal stability.

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.
