What Is Keyboard Foam? Enhance Your Typing Experience with High-Performance Polyurethane Foam

What Is Keyboard Foam?

Enhance Typing Feel and Acoustics with Polyurethane Keyboard Foam

Keyboard foam—also known as sound dampening foam for mechanical keyboards—is a specialized material placed between internal keyboard layers such as the PCB and the positioning plate. It reduces typing noise, absorbs vibrations, and protects components, making it a crucial part of modern keyboard design, especially in OEM/ODM production.

Why Use Keyboard Foam in Mechanical Keyboards?

Keyboard foam improves both feel and function in several important ways:

✅ 1. Noise Dampening

Helps reduce high-pitched sounds and vibrations caused by key switches. Especially useful for hollow keyboard cases.

✅ 2. Enhanced Typing Experience

Adds a layer of cushioning that softens the bottom-out keystroke, making typing smoother and quieter.

✅ 3. Component Protection

Prevents wear and tear on internal layers like the PCB, plate, and case.

Best Material for Keyboard Foam: Microcellular Polyurethane Foam

Not all foams are created equal. Among various materials, microcellular polyurethane foam is one of the most effective for keyboard acoustic treatment and structural support.

Key Features of Polyurethane Keyboard Foam:

• High elasticity and resilience

• Superior vibration isolation and shock absorption

• Excellent acoustic dampening

• Available in customizable thicknesses and densities
