As China's leading manufacturer of premium plastic products, Jinbao PVC specializes in producing high-quality PVC foam boards known for their exceptional water-resistant properties. Understanding water absorption rates is crucial for selecting the right material for your applications, particularly in environments where moisture exposure is a concern.
PVC foam boards exhibit remarkably low water absorption rates, typically ranging from 0.5% to 1% by volume when tested under standard conditions (24 hours at room temperature). This exceptional water resistance stems from the closed-cell structure of the foam and the inherent properties of polyvinyl chloride material.
The density of PVC foam boards plays a significant role in their water absorption characteristics. Higher-density boards (above 0.7 g/cm³) generally show lower water absorption rates compared to their lower-density counterparts. Jinbao PVC offers various density options to suit different application requirements.
The surface finish of PVC foam boards influences their water resistance. Our boards feature a smooth, non-porous surface that creates an additional barrier against moisture penetration, further enhancing their water-resistant properties.
Temperature variations and exposure duration significantly impact water absorption rates. Under normal conditions, our PVC foam boards maintain their low absorption properties even with prolonged exposure to humid environments.
The low water absorption rate makes PVC foam boards ideal for marine applications, where they maintain structural integrity even under constant exposure to moisture and salt water.
In building applications, the minimal water absorption ensures long-term performance in areas prone to moisture, such as bathroom partitions and outdoor signage.
Water absorption testing follows international standards, including:
24-hour immersion tests
Long-term exposure evaluations
Accelerated aging assessments
Jinbao PVC conducts rigorous quality control testing to ensure consistent water resistance across all our PVC foam board products, maintaining our position as an industry leader.
While our PVC foam boards offer excellent water resistance, proper installation and maintenance can further enhance their performance:
Proper sealing of edges in wet environments
Regular inspection for any damage
Appropriate ventilation in indoor applications
With proper care, Jinbao PVC's foam boards maintain their water-resistant properties throughout their service life, typically exceeding 10 years in normal conditions.
Jinbao PVC offers PVC foam boards in various configurations:
Thickness range: 1mm to 30mm
Standard sizes: 1220mm x 2440mm and 1830mm x 3050mm
Multiple density options for different applications
Please note that while we provide these standard specifications, we do not offer customization, cutting, or drilling services.
Understanding water absorption rates is essential for selecting the right PVC foam board for your specific application. Jinbao PVC's premium PVC foam boards offer industry-leading water resistance, making them ideal for applications where moisture exposure is a concern.
