Silica Gel Orange Beads

Orange Indicating Silica Gel, sometimes known as Yellow Indicating Silica Gel, is comprised of a naturally occurring mineral silicon dioxide that is purified and processed into a beaded form. When the beads are dry, they appear yellow/orange in color, and when they have become saturated with moisture to about 15% by weight the beads will change to a green color. This type of indication enables users to visually confirm when the desiccant is needs to be replaced or regenerated.

In 1998, the European Union determined that Blue Indicating Silica Gel, which is contains cobalt dichloride, a known human toxin, and prohibited its use within European markets. Orange Silica Gel conforms to the European Union requirements for moisture indicating desiccants. Similar to Blue Silica Gel, Orange Silica gel is used in a variety of industries and applications, such as compressed air dryers, gas drying and transformer breathers.

Orange Indicating Silica Gel in a 2mm-5mm bead size. Orange Silica Gel also has a high adsorption capacity, and will remove moisture at temperatures as high as 150° F (65°C). However, it is best used at room temperature (70‐90° F /21-32°C).

Orange Indicating Silica Gel is a non-toxic, pollution-free desiccant that will meet the needs of environmentally-conscious companies. That said, Orange Silica Gel should not be used in direct contact with products that are intended for consumption, such as food and pharmaceuticals.

Accidental release measures
Personal precautions Respiratory protection, eye protection Methods for cleaning up Sweep the spil area, avoid rising dust
Handling and Storage
Keep ni a tightly closed container, stored ni a cool, dry, ventilated area. Protect against physical damage. When pouring into a container of flammable liquid, ground both containers electrically to prevent a static electric spark. Containers of this material may be hazardous when empty since they retain product residues(dust, solids); observe al warnings and precautions listed for the product.
Exposure Controls/Personal protection Airborne Exposure Limits: Silica(synthetic, amorphous):
-OSHA Permissible Exposure Limit(PEL)-
80/(%Si02)mg/m3(TWA) for amorphous silica, including natural diatomaceous earth.
Personal Respirators (NIOSHApproved):
fI the exposure limit si exceeded and engineering controls are not feasible, a half facepiece particulate respirator (NIOSH type N95 or better filters) may be worn for up ot ten times the exposure limit or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier, whichever si lowest. Afull-face piece particulate respirator (NIOSH type N100 filters) may be worn up to 50 times the exposure limit, or the maximum use concentration specified by the appropriate regulatory agency, or respirator supplier, whichever si lowest. fI oil particles (e.g. lubricants, cutting fluids,
glycerine, etc.) are present, use aNIOSH type Ror Pfilter. For emergencies or instances where the exposure levels are not known, use a full-facepiece positive-pressure, air-supplied respirator. WARNING: Air-purifying respirators do not protect workers ni oxygen-deficient atmospheres.
Skin Protection:
Wear protective gloves and clean body-covering clothing.
Eye Protection:
Use chemical safety goggles. Maintain eye wash fountain and quick-drench facilities ni work area.
