Cyclo-Olefin Copolymers - Properties and Applications

Background

Cyclo-Olefin copolymers are engineering thermoplastics derived from the ring-shaped norbornene molecule. It is in turn made from dicyclopentadiene (DCPD) and ethylene.

Key Properties

Cyclo-Olefins exhibit:

        Glass-like transparency and high light transmittance

        Low dielectric loss

        Low water absorption

        Low outgassing

        Excellent dimensional stability

        High heat resistance

        Good chemical resistance

        Hydrophobic properties

        High melt flow rates allowing precise moulding

        Lower density than glass

Applications

Cyclo-Olefins are used for:

        Light guide panels

        Laptop computer screens

        Contact lenses

        Compact discs

        Barrier sheets in medical applications

        Packaging films and blister packs for medication packaging in which case a layer of cyclo-olefin copolymer may be laminated between layers of polypropylene.

        Bottles such as those used for cosmetic packaging

        Lenses

        Automotive parts

        Industrial parts
