Original Press Release:



Humidity Sponge - Regenerable/Indicator



The latest in drying technology turns any container into a desiccator. Indicator bag particles show when moisture capacity has been reached.

Nontoxic and ideal for clean rooms

Humidity Sponges(TM) meet FDA requirements for use in direct contact with food and drugs. Desiccant (sodium calcium aluminosilicate hydrate) is nontoxic and is a GRAS (Generally Recognized as Safe) material. Ideal for storing food/pharmaceutical samples, electronics, PC boards, optics, chemicals and equipment.

Outer material is made of DuPont's Tyvek breathable, high-density polyethylene. Zero-Dust bags are certified as Class M3.5 (formerly Class 100) clean room compatible.

Retains 16% moisture, guaranteed

Drying capability depends on volume, temperature and moisture. As a benchmark, one bag will maintain dry conditions in a container with a volume of two gallons (476 cubic inches/7800 cubic centimeters). Bags are guaranteed to retain 16% moisture by weight; typical results are 37% moisture absorption. Each bag measures 3 x 3 x 1/4 inches and weight is 3/8 ounce.

Indicator Humidity Sponges(TM)

Indicator Sponge has one side of clear film and one of white Tyvek. It contains blue particles which turn pink when the desiccant has reached its moisture capacity and needs to be replaced. Indicator Humidity Sponge(TM) cannot be regenerated.

Regenerable Humidity Sponges(TM)

Regenerable Sponge has white Tyvek on both sides and may be regenerated and reused continuously. Regeneration requires heating in an oven at 220°F (104°C). Included in each pack is a Relative Humidity Card which changes from blue to pink to show when bags need to be regenerated.
