Thunder Mats are multi-layered tacky film mats designed to capture particulate from foot and cart traffic upon entering a clean environment. Thunder Mats feature numbered corner tabs on each tacky sheet, making it easy to track the remaining sheets and know when it's time for a replacement. Engineered to withstand heavy foot traffic and cart wheels, Thunder Mats provide a robust barrier against outside particulate while maintaining a smooth surface. The peel-off sheets eliminate the need for messy cleaning and make it effortless to maintain a clean surface. Simply peel away the top layer when it's dirty to reveal a fresh, tacky sheet underneath. These mats are ideal for cleanrooms, laboratories, industrial settings, and other environments that require strict control of dirt, dust, and other particulate.
