Arlon’s 85HP is the best in class 250⁰C high glass transition temperature polyimide resin system available on the market today. This unique blend of polyimide resin and micro-fine proprietary fillers results in superior performance for the most demanding thermal and high layer applications. Compared to conventional polyimide systems, 85HP has a lower Z-axis expansion and twice the thermal conductivity of conventional polyimide resin systems. 85HP has proven to reduce cracking and wicking in high layer, high density, thick copper designs that challenge conventional resin systems. Applications for 85HP include mission critical PWB’s for military, aerospace, space, down hole oil and gas drilling and many other high reliability applications. Meets requirements of IPC-4101/40 and IPC-4101/41.
