Full definition
Rubber flooring engineered to maintain flexibility, non-slip properties, and structural integrity at sustained temperatures of -25 to +5°C inside refrigerated storage rooms, freezers, and cold processing areas where standard flooring materials become brittle and slippery. Material selection is critical: EPDM or NR-based compounds (glass transition temperature well below -40°C) maintain elasticity and anti-slip properties at freezer temperatures. SBR becomes stiff below -20°C and is not recommended. Key requirements: non-slip in wet conditions (condensation and frost are constant — aggressive textured surface, COF >0.5 per ASTM D2047 at operating temperature), resistance to freeze-thaw cycling (repeated temperature swings from warm loading to cold storage), anti-fatigue properties (cold room workers stand on hard, cold concrete), thermal insulation (reduces heat loss from cold slab into the room), and compatibility with cleaning chemicals. Thickness: 8-12 mm (thicker for insulation and cushioning). Installation: moisture-resistant PU adhesive (standard water-based adhesives fail below 5°C). Pre-condition adhesive and flooring above 15°C before installation, then allow cure before lowering room temperature. Per FDA 21 CFR 177.2600 for food-contact areas. Brands: Nora, Mondo, Regupol.
