polymer

This is a dielectric polymer material engineered for electrical insulation applications, identified by its dielectric constant value of 2.77. The designation suggests a specialized polymeric formulation optimized for capacitive or insulating performance in electronic systems where controlled permittivity is critical. Dielectric polymers of this class are widely used in capacitors, printed circuit boards, high-voltage insulation, and electronic packaging where low electrical losses and stable dielectric properties are essential; the specific dielectric constant of ~2.77 positions this material for applications requiring moderate permittivity—useful in signal integrity, power distribution, and thermal management applications where lower-permittivity alternatives may be insufficient.

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.
