Product Details
400 kg/m³ PVC Foam Sheet is a high-density closed-cell structural foam engineered for applications requiring exceptional compressive strength, dimensional stability, and long-term durability. Manufactured from premium polyvinyl chloride (PVC) resin through an advanced foaming process, this rigid foam sheet combines lightweight performance with outstanding mechanical properties.
Compared with lower-density PVC foam, the 400 kg/m³ PVC foam sheet offers significantly higher compressive and shear strength, making it an excellent core material for composite sandwich structures, industrial components, marine applications, transportation, and construction projects.
Its closed-cell structure provides excellent resistance to water absorption, chemicals, corrosion, and weathering, ensuring reliable performance even in demanding indoor and outdoor environments. The material is easy to machine, thermoform, bond, laminate, and CNC process into complex shapes, making it ideal for custom manufacturing.
