High-quality PDMS (polydimethylsiloxane) sheets available in thicknesses from 20 µm to 3000 µm and 250 x 250 mm dimensions. Ideal for easier microfluidics devices fabrication, but also for biomedical devices and electronics.
General
Our PDMS (polydimethylsiloxane) sheets are manufactured to meet the requirements for your microfluidics devices fabrication. Available in a variety of thicknesses from 20 µm to 3000 µm, our PDMS sheets offer excellent flexibility and durability.
They can be used to be integrated into your microfluidics devices or as a sealing solution for you chips. They are also suitable for a wide range of applications in industries such as biomedical devices, electronics, and more.
The PDMS sheets are chemically inert, resistant to oxygen, ozone, and ultraviolet (UV) radiation, and highly permeable to gas and water vapor.

(1) Thicker PDMS sheets are supplied with a thin layer of white powder (talc) to prevent them from sticking to each other. Before use, we recommend cleaning the sheets with a mild soap solution to remove any talc residue. Preferably, use a neutral soap (without additives, perfume, or added glycerine) to minimize any risk of residues remaining on the PDMS surface.
