PVC is a plastic material that is commonly used for manufacturing packaging, piping, and other applications. It is generally considered to be non-waterproof, but certain grades of PVC may be waterproof. However, the waterproof characteristics of PVC are usually determined by the manufacturer and type of PVC used, so it is difficult to determine whether PVC banners are waterproof without specific information about the type of PVC used. It should be noted that protecting PVC items from water damage can help prolong their service life and avoid damage from water damage during transportation. If you need to know whether your PVC banner is waterproof or not, it is best to contact the manufacturer or distributor for more information.
PVC is an unsatured, which is generally used to manufacture temporary store walls, railings and protective floors for residential areas, offices, campuses, stadiums and other venues. This is because the hydrolysis and oxidation of PVC in the presence of moisture can cause the material to yellow or peel, and ultimately accelerate the growth of microorganisms, so that cleaning work requires greater labor hours to effectively disinfect and eliminate bacterial growth.
To protect the surface of PVC banner from moisture and provide more stability, you can apply waterproof coatings. These coatings can be applied by professional coatings companies or DIY. The waterproof coating can effectively prevent water from penetrating into the PVC banner and protect it from oxidation and hydrolysis. However, the waterproof coating will also increase the cost of the banner.
Therefore, if you want to use PVC banner in a waterproof environment, it is recommended to choose a material with higher resistance to hydrolysis and oxidation, such as PET plastic.
