polymer

This is a polymer dielectric material designed for electrical insulation applications where controlled permittivity is required. Based on its designation, it belongs to the family of engineered polymers formulated to achieve specific dielectric performance characteristics, making it suitable for capacitors, circuit boards, and other electronic components where precise electrical behavior is critical. The material is chosen over standard polymers when applications demand balanced dielectric properties with good processability and cost-effectiveness compared to 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.
