The MW1000-series microwave absorbing materials are developed to meet the requirements of complex mechanical structures and high-volume production. The main working frequency is in the millimeter wave range.
The MW1000- series series uses various polymers as carriers, filled with specially formulated ferrite to form composite materials, which can effectively help improve antenna gain and reduce intracavity resonance.
The MW1000-series has excellent environmental adaptability to harsh environmental conditions: wide operating temperature range, oil resistance and UL-94 V0 flame rating. Material can be molded into complex shapes according to mechanical design. The magnetic filler makes the product have excellent wave absorbing performance even when the incident angle is greater than 65 degrees.
