polymer

This is a polymer-based dielectric material characterized by a relatively high dielectric constant (approximately 5.7), making it suitable for electrical insulation and capacitive applications where moderate permittivity is advantageous. The material is typically used in electronics, power distribution, and RF/microwave applications where controlled dielectric behavior is needed to balance electrical performance with mechanical properties. Compared to standard polyethylene or polypropylene, this polymer offers enhanced electrical performance in capacitors and insulation layers without the brittleness of ceramic dielectrics, making it a practical choice for applications requiring both electrical functionality and material toughness.

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.
