Polyramic® - Resins for Electronics Laminate
Starfire® Systems has developed a class of "green" polymers called Polyramic® that combine organic manufacturing processes with the performance and stability of inorganic materials. Laminates produced from Polyramic® provide the electrical engineer exceptional flexibility with demonstrated properties including low loss factor (Df of 0.0015), low dielectric constant (Dk of 2.9), halogen free / RoHS compliance, inherent flame retardance (UL-94 V-0), and a low stable x,y CTE (8 - 10 ppm/°C) before the addition of filler materials. Polyramic® have been studied by the Packaging Research Center at Georgia Tech.
