TOPAS® COC Grades (Cyclic Olefin Copolymer)

Cyclic olefin copolymers are a class of polymeric materials with property profiles which can be varied over a wide range during polymerization. Performance benefits are: Low density High transparency Low birefringence Extremely low water absorption Excellent water vapour barrier properties Variable ...

TOPAS COC Elastomer is a variant of COC that offer a unique set of properties because it’s a pure polymer
• Ultra low level of extractables • Good mechanical properties (as a static gasket) • Excellent static leakage performance • Good moisture ingress barrier

Polyplastics has commercialized DURACON® POM (Polyoxymethylene / Acetal) PM Series for medical applications.In the medical device marketplace, manufacturers and end users demand high quality materials from reliable suppliers. As the world’s leading manufacturer of POM, Polyplastics now adds DURACON®&n...

The combination of high transparency, higher shatter resistance than glass and excellent moisture barrier makes TOPAS® COC particularly attractive for prefillable pharmaceutical primary packaging. The material is also characterized by high purity and excellent biocompatibility.
Examples of applications include prefillable syringes and vials as well as a variety of prefillable containers that can be used, for example, as part of injection systems.
Injection molding and injection blow molding/stretch blow molding are typical manufacturing processes for this type of pharmaceutical packaging.
In addition, TOPAS® COC is increasingly used for pharmaceutical blister packaging due to its high transparency, biocompatibility and excellent moisture barrier.

Packaging for medicines and medical devices must meet such demanding criteria as biocompatibility, protection against external influences, optimum shelf life, clear labeling and easy handling and removal. Blister packs have become increasingly popular for medicines in tablet form because they are easy and safe for patients to use and help them to comply with dosage recommendations. Modern medical devices often need to be protected from moisture, while clarity is desired for easy identification and quality control.
