TOPAS COC

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  • E...

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.
