If you are looking for a solution to microfluidics mass production, our Flexdym pellets may be the perfect material for you.

Microfluidics Scalability Challenges

Microfluidics suffers from a lack of both biocompatible and scalable materials for mass production of microfluidic chips. In this domain, academics favor elastomeric materials, such as PDMS (polydimethylsiloxane), for device prototyping. And although PDMS has a relatively simple fabrication protocol, it also lacks scalability. In fact, PDMS microfluidic devices must be manually bonded and assembled. This hampers commercialization.

On the other hand, industry experts prefer thermoplastic materials, including COC, COP, PS, or PC. This is due to their scalability and compatibility with mass production processes, e.g. injection molding. However, these materials also harbor drawbacks for biomedical applications. For example, they require bonding treatments with harsh chemical and temperature conditions, that are not ideal for surface functionalization. Additionally, they are expensive to use at prototyping stages – limiting their widespread use.

The Flexdym Solution

To solve this issue, we have created Flexdym. Flexdym is a popular alternative to PDMS and specifically created for the scale up of microfluidics devices, thanks to its compatibility with mass production processes. Moreover, Flexdym is ideal for biological applications, because it is certified biocompatible ISO 10993 (parts 4, 5, 6, 10, 11) and UPS Class VI. This demonstrates Flexdym’s low toxicity and its ability to be used for medical applications. Other advantages of Flexdym include optical transparency and low molecular sorption, which make Flexdym a top choice for cell culture and diagnostic applications.

Now you can finally use the same material at all scales, from prototyping to mass production of your chips. Flexdym makes commercialization of microfluidic chips easy.

Flexdym Pellets for Mass Production

Eden Tech has created the Flexdym pellet format as a low cost option for mass production. Flexdym pellets are ideal for commonly used injection molding. But they can also be used for small scale production with the help of a classic hot press.

The pellets can be molded at small scales, suing our Sublym or a hot press, and at large scales using injection molding.

Bond Flexdym to substrate

Versatility: Flexdym Bonding Strength

Flexdym combines the best properties of elastomers, like PDMS, and thermoplastics, like COC, polystyrene or polycarbonate. Flexdym acheives this through its block co-polymer structure composed of styrenic hard blocks and ethylene-butylene soft blocks, which allow it to remain soft, yet compatible with hot embossing.

Flexdym acts as a pressure sensitive adhesive, bonding with a selection of substrates through conformal contact. Flexdym bonding can be accomplished through manual lamination using a roller, or standardised through the use of a press.

Flexdym can be recycled and reused. Simply wash or sterilize the molded material (e.g. via gamma treatment) and re-mold.

Finally, Flexdym has tunable bonding strength, which varies according to the material selected as a substrate.
