Topas Cyclic Olefin Copolymer (COC)
Cyclic olefin copolymers are a new class of polymeric materials that exhibit a unique combination of properties which can be customised by varying the chemical structure of the copolymer.
Performance benefits include:
Low Density
High Transparency
Low Biofringence
Extremely Low Water Absorption
Excellent Water Vapour Barrier Properties
Variable Heat Deflection Temperature up to 170oC
High Rigidity, Strength and Hardness
Very Good Blood Compatibility
Excellent Biocompatibility
Very Good Resistance to Acids and Alkalis
Very Good Electrical Insulating Properties
Very Good Melt Processability/Flowability
Topas COC resins are suitable for the production of transparent mouldings for use in optical data storage, optic eg lenses, sensors and industrial products.
These materials are also of particular interest for primary packaging of pharmaceuticals, medical devices and diagnostic disposables.
Topas is
currently supplied as an unreinforced water-clear transparent material.
Glass-filled, tinted and pigmented formulations are also under
development.
