What are the friction coefficients for different tabletop materials to prevent item slippage?

When selecting tabletop materials for homes, offices, or industrial settings, understanding their friction coefficients is crucial to prevent item slippage. The friction coefficient measures the resistance between two surfaces, indicating how well objects stay in place. Here’s a breakdown of common materials and their typical friction coefficients:

1. Wood: With a static friction coefficient of 0.25–0.5, wooden surfaces offer moderate grip. Finished or polished wood may reduce friction, while rough or unfinished wood provides better traction.

2. Glass: Smooth glass has a low friction coefficient (0.1–0.2), making it prone to slippage. Textured or frosted glass can improve grip slightly.

3. Plastic (Laminate): Laminate tabletops range from 0.2–0.4, depending on texture. Matte finishes generally outperform glossy ones in preventing slippage.

4. Metal (Stainless Steel): Polished metal surfaces are slippery (0.1–0.3), but brushed or textured metal can increase friction to 0.4–0.6.

5. Rubber or Silicone Mats: These provide the highest friction (0.6–1.0), ideal for securing items. They’re often added to other materials to enhance grip.

For optimal stability, consider pairing high-friction materials with non-slip pads or textured finishes. Understanding these coefficients helps in choosing the right surface for your needs, whether for dining tables, workbenches, or display areas.
