| PREPERM® L300 is a special compound with elevated dielectric constants of 3.0. PREPERM® L300 is based on Premix proprietary PPE technology. Extremely low dissipation factor (0.0005) makes PREPERM® L300 an excellent material for high frequency applications. PREPERM® L300 offers stable dielectric constant over wide frequency and wide temperature range. PREPERM® retains its physical properties at very low (-78°C) temperatures. PREPERM® L300 can be injection moulded or extruded. Applications include structural parts for antennas in base stations, point to point, wlan, mobile phones etc. Devices made out of PREPERM® L300 can operate at very high frequencies as PREPERM® L300 offers stable performance even at 120 GHz.&& |
