Pemasok yang Diaudit ORANGE SILICA GEL is a heavy metal free, environmental-friendly humidity indicator SILICA GEL for protection of goods and miscellaneous substances widely USED in Transformer Breathers & Air Dryer in Power Sector.
ORANGE SILICA GEL is an alumino-silicate gel in the form of hard Round Shape or Spherical Beads form, with a very high resistance to crushing and a low attrition rate. Orange Silica Gel has a longer life than most other adsorbents and can reduce operating costs in most applications. It is also known as Nontoxic Indicating Silica gel
Orange Indicating Silica Gel is a spherical/beads type with very high mechanical integrity. The degree of moisture uptake is indicated by a color change from orange to Green & Orange to Colorless at 6 - 8 % weight water absorption. Silica Gel Orange meets the world demand for a heavy metal free and environmental friendly indicating agent.
Orange Silica Gel Available Sizes: 1-3 mm, 2-4 mm, 3 - 5 mm
Non-indicative white silica gel:
