Thermal + EMI Absorbing
RF Absorber Selection Guide: Applications & Specs
An RF absorber is a tuned part, not a broadband wall. See the five application families, why their dB numbers differ, and the checks to run before you commit.
ZIITEK Knowledge Hub
Thermal management, explained by the engineers who make it.
Selection guides, comparisons and compliance references for thermal interface, sealing, EMI-absorbing and heating materials — grounded in real datasheets and real designs.

Materials & Selection
Which material fits the job — and how to read the spec sheet before you commit.
By Application
Thermal design worked through end to end, per industry and per board.
Specifying & Sourcing
Drop-in replacements, compliance evidence and converting — from spec to purchase order.

Sealing & Cushioning
Open-Cell vs Closed-Cell Foam for Gaskets
Open-cell foam cushions and absorbs sound; closed-cell foam seals water out. Compare compression set, water absorption, IP ratings and flame behaviour.

How Long Do Thermal Pads Last? Life by Application
Thermal pad life is three clocks, not one: up to 12 months in storage, 3-10 years in service, and zero recovery once a pad is re-clamped. How to tell which.

High-Conductivity Thermal Pads (15–18 W/mK)
Server pads at 15–18 W/mK only pay off when the bond line is thin and the pressure is real. Read the datasheet, size hardness, set assembly pressure, qualify.

Thermal Runaway: Materials That Help Contain It
How mica, aerogel, ceramic-fiber and silicone-foam barriers slow thermal runaway propagation between cells, and the specs to check before you specify.
Die-Cutting & Converting
Custom Die-Cut TIM Parts: A Capability Checklist
A custom die-cut TIM part is a stack, not an outline. Seven questions — material, tolerance, format, operations, tooling, delivery, quality — set feasibility.
