ART SORB sheet 50% RH

ART SORB is a silica gel for stabilizing the relative humidity inside museum showcases. ART SORB sheets are a non-woven fabric made of PE / PP impregnated with ART SORB. Each sheet contains 100 g of ART SORB. For 1 m³ of showcase volume you will at least need 5-10 sheets depending on your needs.

Size: 500 x 500 x 1,8 mm. Dry weight about 160 g/sheet (100 grams of ART SORB per sheet). They are composed of ART SORB particles bound in a PE/PP non-woven.

ART SORB sheets are ideal for small spaces such as framing systems and for vertical applications like on back side of display cases. Due to their large active surface sheets are often used to buffer short term changes in relative humidity. They can be cut to appropriate size with a pair of scissors or a cutter knife. ART SORB sheets are available pre-conditioned at 50% RH only, but they adapt rapidly to other climatic situations when exposed in a room with a given relative humidity.

In many applications ART SORB sheets can be replaced by thick, acid-free, archival passe-partout cardboard that have been exposed for >2 days in a room with corresponding climate.
If the buffering capacity of the sheet will notbe sufficient, PROSORB panels or PROSORB sachets can also be used. The latter are also available with suspension holes or in a "quilted version", avoiding that all bead collect at the bottom of the sachet when mounted vertically.

Please be aware that these sheets give off fine dusts of ART SORB during handling. This dust contains corrosive LiCl and should not get into contact with art works, especially metals. Be sure not to transfer any of this dust onto your artwork via your hands or gloves. To be on the safe side concering dust the ART SORB sheets can be sealed into permeable but dustproof materials like TYVEK.

Please note: The specification of 50% RH for the preconditioning of the sheets is based on the manufacturer's information. The actual preconditioning of the sheets is not verified by us.
