polymer

This is a polymer material characterized by a low dielectric constant (approximately 2.48), making it part of the family of low-loss electrical polymers used in high-frequency applications. Such materials are employed in electronics and telecommunications where signal integrity and minimal dielectric loss are critical, particularly in printed circuit board substrates, transmission line insulators, and microwave components where they reduce signal attenuation and crosstalk compared to standard polymer dielectrics.

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.
