polymer_dielectric_constant_188
polymerThis is a polymer-based dielectric material, likely engineered for electrical insulation applications where a moderate dielectric constant (approximately 1.88) is desired. Polymers with this dielectric range are commonly used in capacitors, printed circuit boards, and cable insulation where a balance between electrical performance and mechanical processability is required. This material would be selected when higher dielectric constants (ceramic or filled polymers) are unnecessary, offering advantages in weight, cost, and ease of fabrication 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.
