Comparing PDMS, glass, microinjection molding, and Edge Embossing
Optical clarity: refers to transmission of visible wavelengths through the material, which can vary widely by material grade
Rigidity: refers broadly to tensile strength and resistance to bending force
Chemical resistance: refers broadly to how well the material resists chemical reaction with organic solvents such as ethanol, methanol, acetonitrile, dichloromethane, and others. Please refer to the linked datasheets to find out about the resistance of a particular grade of material to a particular solvent.
Non-specific binding: refers broadly to non-specific adsorption of proteins, cells, and similar to the surface of the material
Hydrophobicity: refers generally to how much the material resists wetting by water and aqueous liquids. This is typically characterized by a larger surface contact angle as well as propensity of the material to retain air bubbles and exhibit difficulty in fully wetting
Background fluorescence: refers generally to the intensity of fluorescence contained in the material as produced. For many thermoplastics, normal additives in the source resin or small molecules produced during extrusion or molding fluorescence at wavelengths similar to those used for many biochemical assays
