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.
