EUROPLEX® COC FILMS FOR MICROFLUIDIC APPLICATIONS
Technical Information
Product Characteristics
High transmission
EUROPLEX® COC Films for microfluidic applications provide excellent light transmission and brilliance due to a low intrinsic absorption.
Chemical resistance
EUROPLEX® COC Films exhibit outstanding chemical resistance for a variety of solvents, e.g. acetone, ethanol, isopropanol, ethyl acetate, as well as very good acid and base resistance.
Thermal stability
Two types of EUROPLEX® COC Films are available with glass transition temperatures of 78°C and 142°C, respectively. This helps customers to realize applications with various requirements in thermal stability.
Biocompatibility
With regard to the composition, the applied COC polymer material complies with the regulations of the European Pharmacopoeia, Monograph 3.1.3. “Polyolefines”.*
Processability
EUROPLEX® COC Films can be easily processed by laser cutting and laser welding.
Bonding-process
The following bonding-processes are suitable:
- Laser welding
- Thermal bonding
- Solvent bonding, e.g. using cyclohexane or toluene
- Ultra sonic welding
