Expanded PVC and PVC are both thermoplastic materials made of polyvinyl chloride as the main raw material, but they have different properties, characteristics and uses.

PVC, also known as rigid PVC or solid PVC, is a durable, rigid plastic material. It is widely used in various industries due to its excellent chemical resistance, strength and durability. PVC is commonly used in applications such as pipes, fittings, window frames and electrical insulation.

Expanded PVC, on the other hand, is a foamed version of PVC in which a foaming agent is added during its manufacture to expand it and form a cellular core structure filled with tiny air bubbles. This foaming process gives expanded PVC its lightweight nature while still maintaining its strength and rigidity. Expanded PVC is commonly known as foam PVC or PVC foam board. It is available in sheets of various thicknesses and sizes for use in signage, displays, furniture, decorating, model making and construction industries.

1. Rigidity: PVC is known for its rigidity and strength, making it suitable for structural applications. On the other hand, expanded PVC has a lower rigidity due to the presence of air cells. While still providing good strength and stability, expanded PVC is more flexible and somewhat less rigid than solid PVC.

PVC: Due to its rigid nature and high strength, PVC is commonly used in applications that require structural stability and durability. It is widely used in the construction industry for pipes, fittings, window frames, and roofing membranes. PVC is also used in electrical insulation, automotive components, and other industrial applications.

Expanded PVC: Expanded PVC, with its lightweight and versatile characteristics, finds application in various industries. It is commonly used in signage, displays, model making, exhibition stands, interior design elements, and advertising boards. Its excellent printability, ease of fabrication, and cost-effectiveness make it a popular choice for visual communication and creative projects.
