PREPERM® L700HF is a special compound with elevated dielectric constants of 7.0. PREPERM® L700HF is a special compound based on Premix proprietary PPE technology. Extremely low dissipation factor (< 0.001) makes PREPERM® L700HF an excellent material for high frequency applications. PREPERM® L700HF offers stable dielectric constant over wide frequency and wide temperature range. PREPERM® L700HF is modified for injection moulding. Applications include structural parts for antennas in base stations, point to point, wlan, mobile phones etc. Devices made out of PREPERM® can operate at very high frequencies as PREPERM® offers stable performance even at 120 GHz. |
