Stratocell® S is the standard medium-density grade foam in the range, with a nominal density of 30kg/m3.
The density, closed-cell structure, and polyethylene material mean that Stratocell® S provides high resilience, excellent recovery after repeated compressions, and mid-range stiffness (which makes it suitable for intricate die-cutting and fabrication). It is ideal for protecting consumer electronics, delicate scientific instruments, and similar semi-fragile items. Stratocell® S is often preferred over low-density grades because it provides improved multi-drop protection, ensuring packaging performance doesn’t degrade after the first impact.
Whether you are looking for Stratocell® S in material form or converted into end caps, pads, dunnage, or other foam packaging, we can help. Our foam experts have extensive experience helping businesses like yours source the optimal foam for their applications.
