Bottom Layer: Thickness 5 mm, Flammability Rating UL94 HB

Component Specifications

Definition

The bottom layer is a critical structural component of anti-fatigue mats, engineered to distribute weight evenly, absorb impact forces from standing workers, and provide a stable base that prevents mat slippage. It interfaces directly with the floor surface while supporting the top comfort layer, typically featuring specialized geometric patterns or cellular structures to enhance durability and ergonomic performance in industrial environments.

Working Principle

Operates through compressive deformation and energy dissipation: when pressure is applied (e.g., from standing workers), the material compresses to absorb shock and reduce strain on legs/feet, then returns to original shape. The textured underside increases friction with flooring to prevent movement, while the internal structure distributes load across the entire mat surface.

Materials

High-density closed-cell foam (EVA, PVC, or polyurethane), rubber compounds (natural/synthetic), or thermoplastic elastomers (TPE). Density range: 300-800 kg/m³. Thickness: 3-10 mm. Shore hardness: 40-70A.

Frequently Asked Questions

What is the primary function of the bottom layer in anti-fatigue mats?

To provide structural stability, prevent slipping, and enhance shock absorption by distributing weight evenly across the floor surface.

How does material density affect performance?

Higher density materials offer better durability and load distribution but may reduce comfort; optimal density balances support with ergonomic benefits.

Can bottom layers be replaced separately?

Typically integrated during manufacturing; replacement requires full mat substitution unless designed with modular components.
