The Sublym hot embossing machine is the first portable plug-&-play hot embossing machine on the market. It is also dramatically cheaper than classic hot embossing machines priced in the range of hundreds of thousands of dollars. 

Flexdym Roll - Microfluidic Product Development

Flexdymâ„¢ Roll – Microfluidic Device Development

The Flexdym rolls are ideal to boost your device product and more cost-effective than our starter pack. The rolls are available in 3 standard lengths: 20 meters, 35 meters or 90 meters. Each roll is approximately 17 cm wide.  The thickness of the sheet is then available in 4 different thicknesses: 250 µm, 750 µm, 1200 µm and 2000 µm.

Flexdym Rollâ„¢ – Microfluidic Device Development 

Want to boost your microfluidic device development with a scalable and cost-effective alternative to PDMS?

The Flexdym™ is the new biocompatible alternative to PDMS specifically created for the scale up of microfluidic devices and microfluidic device development, in both academia or industry. Flexdym is ideal for biological applications, such as organ-on-chip and point of care diagnostics, because it is certified biocompatible. More specifically, Flexdym™ is certified ISO 10993 (parts 4, 5, 6, 10, 11) and UPS Class VI,  tested for toxicity and can be used for medical applications. Other advantages of Flexdym™ include optical transparency, low molecular sorption properties and reduced gas permeability.

Flexdym is a block co-polymer that combines the best properties of PDMS and thermoplastics. With Flexdymâ„¢ device replication is done in minutes and device assembly is a no treatment process. Flexdymâ„¢ bonds to a variety of substrates including COC, COP, PS, PC, PMMA, and PDMS. But the bonding strength varies according to the substrate, providing the option between reversible and permanent bonding (see table below). For this reason, Flexdymâ„¢ is an excellent option for wearable devices, flexible electronics, or reversible sealing of microfluidic cartridges.

The Flexdymâ„¢ rolls are the perfect format for users who need a more cost-effective option after testing our starter pack, but it is also compatible with roll-to-roll embossing methods of mass production. Here, the price per device decreases dramatically, as the roll length increases.

If you are interested in first testing out the Flexdym polymer, check out our Flexdymâ„¢ Starter Pack. But if you are interested in Flexdymâ„¢ for injection molding mass production or 3D printing, you should see our Flexdymâ„¢ Pellets.

Flexdym Handling

A Flexdym sheet is protected with films on either side, to avoid contamination of the material by dust particles or other substances. Keep the protective films on the sheet when cutting (using scissors or die cut). Remove the films once you are ready to sandwich your Flexdym sheet between your mold and counter mold.

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.

Flexdym Mechanical Properties.

Flexdym combines properties of thermoplastics and elastomers. This explains it’s elasticity (Young Modulus of 1.15 MPa) and simultaneous ability to be hot embossed. 

Molding Flexdym:
The Sublym Machine vs. A Hot Press

Eden Tech’s mission is to create user-friendly microfabrication solutions to help researchers boost chip production. With the creation of Flexdym, it was important to offer an affordable machine to mold the material.

Flexdym’s thermoplastic properties means it can be molded via hot embossing, just like other thermoplastics (e.g. COC, polystyrene, or polycarbonate). Hot embossing involves utlizing pressure, heat and  time to transfer features from the mold to the material. Hot embossing is a great alternative to casting and soft-lithgraphy methods of microfabrication.

Explore below 2 methods of hot embossing: 

Sublym Machine

Optimized for Flexdym molding in only 1-2 minutes!

Compact & User-friendly design that requires little to no training.

Dramatically cheaper than most standard clean room equipment. This small investment is an opportunity for you to begin exploring microfluidics. Read more

Molds For Hot Embossing

Expoxy-resin mold | Eden Tech

Epoxy Resin Mold

Epoxy resin molds are one of the best options for hot embossing. They remain robust through repeated molding cycles. Our Epoxym kit enables the fabrication of epoxy mold replicas from Silicon wafers.

Glass Mold

Glass Mold

Etched glass molds are another robust option for hot embossing. 

 

 

 

Metal Mold

Metal Mold

Metal molds, such as those made from aluminium, are a good option. 

 

 

 

Silicon Wafer

Silicon Wafer

The least ideal option for hot embossing are SU-8 & silicon wafers, due to their fragility and ease of breakage. However, when carefully handled and coated with non-stick spray, they do the trick. 


Flexdym Brochures & Documents

Flexdym is our original and patented material, developed by our CEO Emmanuel Roy. Unlike other materials used in microfluidics device fabrication, Flexdym is the first material created specifically for microfluidics biomedical applications. Our Sublym hot embossing machine was then created to render device replication fast and easy. It is compact, user-friendly and affordable. Finally, our Epoxym kit produces robust mold replicas from silicon wafer molds. For more information on any of these products, check out our brochures below.
