What Is Expanded PVC?

Structure of Expanded PVC
Structure of Expanded PVC

Expanded PVC, also known as expanded polyvinyl chloride or expanded PVC foam, akin to cellular PVC materials, is a lightweight and versatile material produced through advanced extrusion manufacturing processes. Its structure is characterized by a closed-cell PVC foam core, which is surrounded by a smooth and rigid outer skin.

●  Closed-Cell PVC Foam Core

This central part consists of a network of closed, gas-filled cells, providing the material with its lightweight properties and excellent insulation capabilities. The closed-cell PVC foam core ensures versatility in the creation of boards and elongated structures.

●  Smooth Outer Skin

Encasing the closed-cell PVC foam core is a smooth and rigid outer skin. This outer layer adds durability and provides a finished surface, making expanded PVC suitable for a wide range of applications.

Types of Expanded PVC Material

Whether you're working on signage, furniture, interior decoration, or construction projects, our expanded PVC solutions — including PVC foam boards, PVC trim boards, and PVC mouldings — offer the perfect balance of durability and workability.
