When purchasing anti-static flooring, do not purchase it if you smell an irritating odor. A good anti-static floor should be moisture-proof. The moisture-proof performance should be reflected by the indicator of water absorption thickness expansion rate, and the higher the value of this indicator, the worse the moisture-proof performance. Floors with poor moisture resistance are highly likely to experience problems such as expansion and deformation in humid environments during the spring and rainy seasons. We remind consumers to purchase flooring with a water absorption thickness expansion rate of less than 10% when making purchases.
