In a world where few manufacturers have the capability to keep EMI shielding and thermal products made under one roof, the latest RF & microwave absorber line completes our advanced product offering.
Our absorbers are offered in the form of automated dispensing epoxy and cavity resonance pads. Both options offer quick-turn prototypes.
The automatically dispensed absorbers reduce RF signals, suppress standing waves and RF noise. In addition, these epoxy absorbers adhere well to metal surfaces, mounts permanently thus avoiding the need for die-cutting for tape. They have low outgassing and are electrically equivalent to our cavity resonance sheets absorber products.
Our epoxy absorber comes in Commercial and High Performance grades to suit your needs:
Our absorber pads survive outdoor exposure and have a wide working temperature range. Designed to be flexible, the absorber pads can be cut and fitted to compound curves. In addition, they have low outgassing and are RoHS compliant and halogen free. The absorber pads are a great cost-effective solution.
Our absorber pads range from Commercial to High Performance grades. Contact our sales team to learn which one best suits your product.

Aerospace technology demands exceptional performance, reliability, and safety. As the industry faces increasing challenges, materials must evolve to meet these needs.
RF absorbers are vital for signal integrity in radar and aerospace, where precision is key. Advanced designs with improved materials and automation enhance reliability and noise suppression, addressing the need for greater accuracy.
E/E architectures are shifting to domain-centralized and zonal models, improving connectivity and integration. TennMax’s thermal and EMI solutions optimize key components for next-gen vehicles.
Here are a few commonly asked engineering and application questions about RF and microwave absorbers:
An RF absorber is a material designed to absorb radio frequency and microwave energy to reduce reflections and electromagnetic interference (EMI).
Common materials include carbon-loaded foams, silicone rubbers, ferrite ceramics, and composites engineered for specific frequency ranges and absorption characteristics.
RF absorbers are used in aerospace, defense, telecommunications, electronics manufacturing, and testing environments to control EMI and improve signal integrity.
TennMax provides a range of RF absorbers including flexible silicone sheets, molded gaskets, and custom form-in-place (FIP) solutions tailored to your application.
Consider frequency range, absorption efficiency, mechanical properties, environmental conditions, and form factor. TennMax experts assist in selecting or custom-designing the ideal absorber.
