What is PVC foam board?
PVC foam board, also known as polyvinyl chloride foam board, is a lightweight board made of polyvinyl chloride resin through a foaming process. Due to its excellent physical and chemical properties, it is widely used in various fields such as construction, advertising, furniture, etc. PVC foam board is waterproof, moisture-proof, mildew-proof, corrosion-resistant, light in weight, and easy to process. It is an ideal multifunctional material.
How is the water absorption of PVC foam board?
Compared with traditional materials such as wood and gypsum board, PVC foam board has extremely low water absorption. This is mainly due to its unique molecular structure and production process. The internal structure of PVC foam board contains a large number of closed bubbles, which not only give the board a lightweight feature, but also prevent moisture penetration.
Normally, the water absorption rate of Cellular PVC foam board after soaking in water for 24 hours is less than 1%. This feature enables PVC board to maintain its physical properties in a humid environment without expansion, deformation or rot. Therefore, PVC foam board performs well in applications that require long-term contact with water, such as outdoor billboards, bathroom partitions, and ship interiors.
What are the advantages of PVC foam board with low water absorption?
Strong durability: Due to the low water absorption of PVC sheet, it will not be affected by moisture and deteriorate in a humid environment, has a long service life, and reduces maintenance and replacement costs.
Anti-mildew and antibacterial: Low water absorption means that moisture cannot penetrate into the interior of the board, thereby avoiding the growth of mold and bacteria and keeping the surface of the board clean and hygienic.
High stability: Under different temperature and humidity conditions, PVC foam board can maintain its size and shape stability and will not deform due to water absorption.
Easy to process: Forex PVC foam board can be cut, nailed, drilled and other operations like wood, but it will not crack or break due to water absorption like wood.
In summary, PVC foam board, with its extremely low water absorption, performs well in many application scenarios that require waterproofing and moisture-proofing, and is a multifunctional material with excellent performance.
