Polysorb Built-in Desiccant Solutions: The Right Choice for a Variety of Rigorous Applications

In today’s business world, ensuring reliability and building trust with customers is critical, given the competitive environment.

The significance of aggressive moisture control — in electronic products, for example — is often not noticed until product failure makes the problem obvious, and by then it is too late. Ensuing deficiencies can result in expensive product loss, customer confidence, and a decrease in loyalty.


Dealing with Permeation and Condensation

A good place to start when dealing with potential water vapor adulteration is to select packaging alternatives with the most minimal water vapor transmission rate available.

Assembly of the device should take place in a temperature and humidity-controlled environment to prevent unwanted moisture from compromising the product. The fact is, though, that the best bulwark against moisture damage is the incorporation of a desiccant.

Essentially, a desiccant absorbs moisture from its surrounding environment. This absorption can be either physical or chemical.

There is a wide variety of desiccants, with each presenting its own adsorption qualities. Special attention must be paid when settling on a desiccant to assure it is compatible with the intended use.

The optimal point at which to incorporate a desiccant into any product is as part of the design process. The choice of a desiccant is contingent on a number of factors:

  • How much moisture should be removed from the headspace air in the package or product?
  • Is there the chance of moisture ingress through the package or product?
  • What is the expected service life of the package or product?
  • What is the desiccant’s compatibility with the product?
  • Are there space constraints?
  • What are the expected environmental conditions that will affect the product during shipping, storage and use?

Polysorb Injection Molded Polymer Desiccant: Smart, Space-Saving Desiccant Packaging Provides Protection for Your Products.

Polysorb from Multisorb Filtration Group transforms conventional internal product components or housings to become their own desiccant packaging. By infusing desiccant directly into the product’s thermoplastic material, the products adsorb moisture in their own hermetically sealed interior space, which is invisible to end-users.

Provides Long-Term Protection

Polysorb provides a high degree of protection, as well as significant vibration-resistance to products that are designed for frequent use and prevents the possibility of consumers disposing of the sorbent.

Saves Space

In applications where space is limited, Polysorb desiccant packaging offers an invisible sorbent solution for an improved level of protection.

Features Customized Adsorption Rates

Polysorb achieves maximum service life protection. By collaborating with Multisorb engineers, customers can implement an adsorption rate specific to their requirements. This provides better exposure time during manufacturing and assembly when compared to ordinary desiccants.

Reduces Shrinkage

Polysorb offers substantial reinforcement over neat resin and provides more advanced injection molding characteristics. The consequence is stronger dimensional stability with less shrinkage.

Typical Applications:

  • Electro-Optical Devices
  • Automotive Electronics
  • Lighting Systems
  • Laser Systems
  • In-Vitro Diagnostics
  • Pharmaceuticals

Polysorb Has Consistently Demonstrated Significant Effectiveness in Preventing Moisture from Disrupting Product Performance.
