Frankly speaking, certain anti‑static floors may contain formaldehyde. Adhesives are adopted during base‑material production, and formaldehyde serves as one of the main components of adhesives. Nevertheless, it does not mean all anti‑static floors are problematic. Compliance with national standards is the critical factor.

What are the stipulations of national standards? According to national requirements, the formaldehyde emission of base materials shall meet Class E1 standard, namely formaldehyde emission below 9 mg/100 g. Higher‑grade products can reach Class E0 (formaldehyde emission ≤ 0.05 mg/m³), and some test results can even achieve ≤ 0.04 mg/m³. Products satisfying above standards are safe for human bodies.

Conditions vary among different materials. PVC anti‑static floors contain no formaldehyde by themselves; ceramic anti‑static floors are inorganic materials with zero formaldehyde emission risks; for all‑steel and calcium‑sulfate floors, attention shall be paid to whether adhesives in base materials and veneers comply with standards.

How to judge during purchasing? Here are three practical tips. First, check test reports. Request suppliers for environmental‑protection test reports issued by third‑party institutions to verify whether indicators such as formaldehyde and VOC conform to national standards. Second, smell samples. Do not purchase products with strong pungent odor. Third, check certifications. Products with China Environmental Labeling Certification (Ten‑Ring Certification) are more trustworthy.

Brief summary: Qualified products manufactured by regular manufacturers guarantee environmental‑protection performance. Avoid cheap, unknown three‑no products, which carry a much higher risk of excessive formaldehyde.
