Full definition
Chemical-resistant flooring for research and testing laboratories where spills of acids, bases, solvents, and biological materials are anticipated. Key requirements: (1) Chemical resistance — withstand dilute acids (HCl, H₂SO₄), bases (NaOH, NH₃), and common solvents (acetone, IPA, toluene) without swelling, discoloration, or degradation. (2) ESD control — conductive or dissipative (10⁶-10⁹ ohms) for labs with flammable solvents or sensitive instruments (ANSI/ESD S7.1). (3) Easy decontamination — smooth, sealed, non-porous surface with welded seams for spill containment. (4) Non-slip — COF >0.5 even after chemical exposure. (5) Stain resistance — light colors (gray, white, blue) for visual detection of spills and contamination. Material options: homogeneous rubber (best overall chemical resistance and durability — Nora is the market leader), vinyl/PVC (wider color range, good chemical resistance), and epoxy/PU resin (seamless coating system, maximum chemical resistance for aggressive environments). Thickness: 2-4 mm for rubber/vinyl tiles and rolls. Installation: full adhesive with heat-welded seams for impervious surface. Per SEFA-3 (Scientific Equipment and Furniture Association — lab floor chemical resistance standard), ANSI/ESD S20.20, and local fire codes for flammable chemical storage areas. Coved base (curved transition from floor to wall) recommended for spill containment. Brands: Nora, Gerflor Mipolam, Forbo, Stonhard.
