Microwave Absorbing Elastomers
RFHP Hi Perm™ & RFUHP Ultra Hi-Perm™
Laird Technologies is introducing new higher permeability material within the Q-Zorb™ microwave absorber product line for enhanced absorption in applications constrained with space limitations.
These new products have higher permeabilities than standard Q-Zorb materials which allow for greater attenuation with thinner material. These materials support a broad frequency range and are comprised of flexible elastomeric material that does not crack or break.
In addition, both the RFHP (Hi-Perm) and the RFUHP (Ultra-Hi Perm) are halogen-free and RoHS certified.
Features and Benefits
- Available in a wide range of dimensions and can easily be die-cut or supplied in kiss-cut pads
- Environmentally friendly – Halogen-free and RoHS certified
- Excellent performance at low frequencies (> 10 MHz)
- Flexible elastomeric material does not crack or break
- Higher permeability than standard Q-Zorb materials for greater attenuation with thinner materials
- Lowers the noise or cavity Q in microwave components
- Pressure sensitive backing is available
- Supports a broad frequency range
- UL V0 flame rating (RFHP Hi-Perm only)
- Very thin materials are ideal for compact applications
