Frequently Asked Questions

What is PE Foam?

PE foam is a durable, lightweight, resilient, closed-cell material that is often used for packaging goods during shipping, due to its excellent vibration dampening properties. However, more recently the community discovered that adding PE Foam in between your PCB and switches can change your keyboard to have a beautiful marble-y sound.

We offer a premium IXPE Foam that is permanently antistatic, so you don't risk destroying your keyboard using common packaging materials. Our Foam Pads are 0.5mm in thickness – thick enough to produce a noticeable difference, but not too thick to where fit and compatibility become an issue.

Why not just use regular, cheap PE Foam?

Our PE Foam is specifically made of IXPE (irradiation cross-linked polyethylene). This material requires a more advanced manufacturing process that results in superior mechanical properties. Compared to common PE, IXPE Foam features much smaller cells and is significantly smoother.

Regular PE Foam found in packaging is not suited for electronics use, since it is not antistatic - this means you risk destroying your keyboard with cheap foam! PE Foam usually has its antistatic properties represented by color:

  • White = No antistatic. Not suitable for electronics.
  • Pink = Temporary antistatic coating that wears over time. Suitable for short-term use.
  • Black = Permanent antistatic. Suitable for applications where long-term ESD properties are required.
How does PE Foam change my keyboard's sound?

PE Foam seems to accentuate mid-range frequencies while slightly dampening both low pitch and high pitch sounds. This means if you have a naturally higher-pitched, poppier keyboard, you may find that PE Foam will deepen its sound. Conversely with a naturally lower-pitched, thockier keyboard, PE Foam may brighten the sound profile instead. For more info, we recommend watching this video from nearLucid.
