You do not need to spend a huge fortune building a full high-spec cleanroom from scratch to create a basic controlled clean production zone for electronics assembly, food packaging or cosmetic manufacturing. The EPS Cement Sandwich Panel is the perfect affordable material to upgrade a regular section of your existing factory into a low-grade cleanroom that meets your basic cleanliness requirements. The smooth, seamless, non-porous cement surface of the panel has no tiny cracks, gaps or rough patches that can trap dust, fibers or particles. You can easily wipe down the entire wall surface in minutes, removing all dust residues completely, which is the most basic core requirement for any cleanroom space. Unlike cheap plastic cleanroom panels that build up static electricity easily, the cement facing of the EPS Cement Sandwich Panel is anti-static, so fine dust particles will not stick to the wall surface and will not get blown around by your cleanroom air circulation system. The tight interlocking joints between panels create a completely continuous wall with no hidden gaps where dust can accumulate, and you can seal all the seams with food-grade silicone sealant to achieve a near-seamless surface that is very easy to sanitize. The excellent thermal insulation of the panels also makes it much easier for your cleanroom HVAC system to maintain a stable, controlled temperature and positive air pressure inside the clean zone, drastically reducing your running energy costs. You can build this basic cleanroom in just a few days, for less than 1/3 the cost of a full professional cleanroom construction. This lets small and mid-sized manufacturing businesses create a compliant basic clean production space, without the huge upfront investment that was previously only affordable for very large corporations.
