Purpose  

To offer the electronics and semiconductor industries an  environmentally friendly Cobalt Free Humidity Indicator  (HI) card.

What are they?

Cobalt Free HI Cards provide humidity level indication  for dry packaging to electronic and semiconductor  manufacturers who desire a card without cobalt.

Why use them?  

Many products are highly sensitive to moisture.  In order  to constantly verify that dry packaging methods are  not compromised during storage and tansport of these  products, humidity indicator cards allow users along the  supply chain to monitor the package conditions.

Indicator spots change from brown to green after  exposure to the relavent relative humidity conditions.  The  cards are reversible and change as conditions change in  the packaging environment, allowing users to monitor the  conditions of product packaging.

The environmentally friendly Cobalt Free HI cards do not  contain cobalt and some configurations can be produced  with less than 900 ppm halogen levels where reqired.

Available configurations

Cobalt Free HI Cards are available in all standard  configurations and humidity ranges, including indications  at 5, 10 and 60 percent relative humidity levels. 

Süd-Chemie continues to manufacture a full range of  blue-to-pink Cobalt-Dichloride based humidity indicator  cards and Cobalt-Dichloride Free HI cards that are also in  full compliance with relevant JEDEC standards and ECB  regulatory, reporting and labeling requirements.
