What is foamex?

Posted by Andy Hayes on

Foamex is a brand name for a type of expanded PVC (Polyvinyl Chloride) foam sheet. It is a lightweight and versatile material commonly used in various applications, including signage, displays, exhibition stands, and model making. Foamex sheets are rigid, durable, and resistant to moisture, making them suitable for both indoor and outdoor use.

Foamex is manufactured through a process called extrusion, in which PVC resin is heated and mixed with other additives. The resulting molten mixture is then forced through a die, creating a continuous sheet. During this process, gas is introduced into the mixture, causing the material to expand and form a foam structure. The thickness of Foamex sheets can vary, typically ranging from 1mm to 30mm or more.

One of the main advantages of Foamex is its lightweight nature, making it easy to handle and transport. It is also relatively low cost compared to other materials such as wood or metal. Foamex is available in different colors and can be easily cut, drilled, and shaped using standard tools. It can be printed on, laminated, or painted, allowing for customization and branding opportunities.

Due to its versatility, Foamex finds applications in various industries, including advertising, retail, construction, and arts and crafts. However, it's important to note that Foamex is not suitable for structural applications or load-bearing purposes as it lacks the strength and rigidity of materials like wood or metal.
