Cleanroom walls are made of materials that are specifically designed to minimize particle generation, control static electricity, and resist chemicals. The choice of materials depends on the level of cleanliness required in the cleanroom and the specific industry standards that need to be met. Here are some common materials used for cleanroom walls: 1.Smooth, Non-Porous Surfaces: Cleanroom walls are typically smooth and non-porous to prevent the accumulation of dust and particles. Common materials include stainless steel, fiberglass-reinforced plastic (FRP), and epoxy-coated surfaces. 2.High-Pressure Laminates (HPL): HPL panels are made by impregnating multiple layers of kraft paper with phenolic resin and topping it with a decorative layer. These panels are durable, easy to clean, and resistant to chemicals, making them suitable for cleanroom walls. 3.Vinyl or PVC Panels: Vinyl or PVC panels are often used in cleanrooms because they are easy to clean, resistant to chemicals, and pro
