polymer

This is a polymer with engineered dielectric properties, designed for electrical insulation and capacitive applications where high permittivity is needed. The material serves specialized roles in electronics, power systems, and RF/microwave components where dielectric constant is a critical performance parameter. Engineers select polymers in this class when they need lightweight, processable dielectric solutions that balance electrical performance with mechanical flexibility and manufacturing convenience compared to ceramic or glass 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.
