FAQ
Q: How does meta-aramid compare to cotton or polyester damper fabric?
A: Meta-aramid (Nomex®) offers 3× the heat resistance of cotton and 5× the fatigue life of polyester. Cotton dampers lose tension after 100–200K cycles at high power; meta-aramid maintains Kms through millions of cycles.
Q: Can you match the compliance (Cms) of my current damper?
A: Yes. We adjust GSM, weave pattern, and resin coating to match your target compliance curve. Send us your current damper spec or a sample, and we'll reverse-engineer the fabric.
Q: Is the fabric pre-coated with resin?
A: We offer both: bare fabric for your in-house resin process, and pre-coated (phenolic/epoxy/polyimide) for plug-and-play stamping. Resin type and coating weight are customizable.
Q: What width is best for high-volume stamping?
A: 160cm is our standard, optimized for maximum die-cutting yield per roll. We can also slit to narrower widths (80cm / 100cm) if your press requires it.
Why Upgrade to Meta-Aramid Damper Fabric?
- 3× the Thermal Headroom vs cotton/polyester — handles sustained 500W+ RMS without compliance drift
- 10× the Fatigue Life — maintains linear Kms through millions of excursion cycles
- Zero Humidity Drift — no shrinkage in tropical climates, no sagging in dry conditions
- Lighter Than Cotton — 158gsm meta-aramid performs like 200gsm cotton at lower moving mass
- Resin Versatility — bonds perfectly with phenolic, epoxy, and polyimide systems
