Pelsorb
Pelsorb is a moisture sensitive silica gel capable of both absorbing and desorbing moisture, making it ideal for stabilizing relative humidty within an enclosed space(Such as museum display cases or storage cabinets).
Pelsorb can be used to maintain a 45 - 55 % RH (Relative Humidity) level and can operate effectively for 5 years or more.
Pelsorb is available in beads and as sachets of beads which should be placed around the perimeter of the case, or in a drawer. Use 1 sachet or 500g of beads per cubic metre (multiply cubic feet by 0.02832 to get cubic metres).
Pelsorb is shipped in aluminium containers that are both moisture and airtight to ensure it arrives in perfect condition for use.
Pelsorb is a suitable alternative to ArtSorb.
