PVC leather is waterproof in humid environment with the following characteristics. Combining material properties and practical application scenarios, a clear conclusion can be drawn:
1.Basic Waterproofing: Dense Surface, Blocking Water Penetration
The core component of PVC leather is PVC resin, which has a tight molecular structure. The relief and coating create a dense surface layer. This physical property effectively stops water from seeping in and keeps the room dry when exposed to humidity for short periods of time,such as rain or splashing water. PVC leather entrance mats, for example, can withstand moisture absorption and deformation in humid environments. When the placenta comes into contact with a fondue or spilled coffee, the liquid stays on the surface, leaving no trace after wiping.
2.Restrictions in Humid Environments: Long-Term Water Absorption Risk
PVC leather is waterproof, but prolonged exposure to humid conditions (such as rainy seasons or poorly ventilated basements) can affect its performance:
Water absorption: Some PVC leather may have mildewed edges or seams due to water absorption by substrates,such as fabric, but the overall surface remains dry. Metamorphosis risk: PVC leather may be slightly deformed if exposed to heavy objects or to high temperature andhumidity for prolonged periods of time, but this is a relatively minor problem under normal use.
3.Compared to Other Materials: Waterproofing is Better Than Genuine Leather and PU Leather
Compared to Genuine Leather: Due to its natural pore structure, real leather absorbs water and expands easily, requiring an extra coating to achieve the same waterproofing as PVC. However, PVC leather requires no complex treatment to achieve basic waterproofing.
Compared with polyurethane leather: PU leather has improved breathability because of its polyurethane properties, but it is slightly less water resistance. PVC leather is more stable in humid conditions and is suitable for outdoor products, luggage and other items that are often exposed to water.
