polymer

This is a synthetic polymer engineered for electrical insulation applications, characterized by its low dielectric constant that minimizes energy loss and signal distortion in high-frequency circuits. The material is commonly employed in electronics and telecommunications where signal integrity and reduced capacitive coupling are critical requirements, making it preferable to standard polymers in applications demanding precise electrical performance.

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.
