Polyester felt

Description

A mechanically bonded, non-woven fabric composed of 100% Polyester fibers. Polyester felt is thick, soft texture with good tensile strength and holds its shape well. It is often used for cushioning in containers and drawers because the texture minimizes the shifting of objects.

Physical and Chemical Properties

• Heat resistance: Generally has good heat resistance, but the specific temperature tolerance varies depending on the type of polyester felt. Some types can withstand temperatures up to 300°F (150°C).  
• Chemical resistance: Resistant to many chemicals, including acids and alkalis.  
• Moisture resistance: Polyester fibers are hydrophobic, meaning they don't absorb much water. This makes polyester felt resistant to mildew and mold.  
• UV resistance: Has good resistance to fading from sunlight.  

Forms and Sizes

Available in rolls and sheets. Thicknesses of 1/8" 1/4" and 1/2" are available.
