PREPERM® L335 is a special compound with elevated dielectric constants of 3.35. PREPERM® L335 is based on Premix proprietary PPE technology. Extremely low dissipation factor (0.0005) makes PREPERM® L335 an excellent material for high frequency applications. PREPERM® L335 offers stable dielectric constant over wide frequency and wide temperature range. PREPERM® retains its physical properties at very low (-78°C) temperatures. PREPERM® L335 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® L335 can operate at very high frequencies as PREPERM® L335 offers stable performance even at 120 GHz. |
