Experience performance beyond standard medical and packaging plastics
TOPAS® COC (cyclic olefin copolymer) is a glass-clear and extremely pure plastic for healthcare, packaging, and electronics applications. From insulin delivery, to food contact films, TOPAS® COC is the high performance material of choice. The broad global regulatory compliance of TOPAS® COC can make your next development a simpler task.
TOPAS® COC is manufactured by our subsidiary TOPAS Advanced Polymers GmbH and sold by Polyplastics in the Americas, Japan and Asia Pacific.
- High purity
- High clarity and gloss
- Heat resistant
- Fine detail reproduction
- Chemical resistant
- Film and molding grades
- Broad regulatory compliance
- Moisture barrier
- Low dielectric constant
- Recyclable with PE
- Easy thermoforming
Introduced in the 1990’s, TOPAS® COC is made with high purity using our original metallocene catalyst process. For demanding medical and diagnostic applications, TOPAS® COC outperforms glass, silicones, PC and other materials, delivering the highest level of performance in drug delivery, medical devices, and diagnostic disposables.
TOPAS® COC resin is a powerful tool for packaging film improvement, delivering improved stiffness, superior twist and cutting in twist films, high shrinkage in shrink films, barrier improvements in food and medical films, and the ability to design high performing recyclable films from a polyolefin (PE or PP) base without incompatible resins or layers.
Raw ingredients and production method
TOPAS® COC is a cyclo olefin copolymer (COC) copolymerized from norbornene and ethylene using a metallocene catalyst.
Comonomer content determines the glass transition temperature, so TOPAS® COC grades with high cyclic olefin content have higher heat resistances.
