Preventing Moisture Damage

Moisture is a detrimental factor when it comes to manufacturing or processing electronics, pharmaceuticals, medical devices, or sensitive chemicals.  Where gaskets and other sealing solutions work to ensure an enclosure is waterproof, that does not guarantee the container is also moisture-proof. ​

​There are many external sources that can go into consideration in regards to ensuring an application is moisture protected.  Permeable material use is one including the use of plastic, rubber or fabrics on the casing or around the casing.  Temperature and other environmental perimeters can also cause part failure in regards to transitioning the humidity to condensation in the field or in shipping.  While the challenge of ensuring the safety of a product in the presence of these variables can be daunting, at FSR we are trying to come up with new ways to solve difficult problems with easy solutions.

Desiccants are non-dusting Tyvek fabric bags with sorbent fill that work to absorb the moisture in an application and prevent failure before it happens.  Commonly used desiccants include:

• Molecular Sieve - Operational in a wide range of environmental conditions with an improved temperature resistance over other sorbents.  Excellent in electro-mechanical and diagnostic applications.
• Silica Gel - Can absorb a variety of chemical substances, however it is more temperature sensitive.  Most commonly used in pharmaceutical and nutraceutical applications.  
• Clay - Inexpensive and reusable, however with an increased risk of releasing moisture at high temperatures in comparison to the Molecular Sieve and Silica Gel.
