For factories that need dust-free or low-dust production environments, such as electronics assembly plants, food processing workshops, and pharmaceutical production facilities, the air tightness and surface smoothness of partition walls are critical to maintain indoor cleanliness, and EPS Cement Sandwich Panel is an ideal material to meet these strict demands. The tongue and groove connection design between panels can be filled with special anti-crack sealant during installation, forming a completely airtight wall structure that prevents outdoor dust from entering the clean zone through wall gaps.

The non-porous smooth calcium silicate face board of the EPS Cement Sandwich Panel does not accumulate dust easily, and workers can wipe the wall surface with a clean cloth or industrial cleaning equipment directly during daily workshop cleaning, which will not leave residual dust in the pores like traditional cement walls. The panel will not shed debris or produce particles after long-term use, which avoids the risk of contaminating precision electronic components or food products. Its stable physical performance will not deform or release volatile substances even in a constant temperature and humidity workshop environment, ensuring that the partition wall maintains high air tightness for more than 20 years. Many clean room construction projects have chosen this panel as the main partition material in recent years, successfully meeting the ISO 14644-1 clean room standards at a much lower total investment than using dedicated clean room metal partition panels.
