ERJ staff report (DS)
Minneapolis, Minnesota -- Plas-Tech Engineering, Inc., a plastics moulding company has used a specialised TPE compound for a new range of single-use syringes.
Plas-Tech uses Teknor Apex's Medalist medical elastomers instead of thermoset rubber for the tiny plunger tips or seals that prevent drugs in the tube or barrel of the syringe from flowing backward as the plunger is depressed. While silicone coatings are widely used to ensure smooth movement of the plunger within the barrel, Plas-Tech uses a non-silicone coating to prevent possible interaction with the drug contents.
The Medalist range of medical elastomers includes many standard high-purity elastomer compounds, along with a comprehensive body of test data and resources for designers and processors. Compounds are available with hardness from Shore OO 25 to Shore A 87 and include clear, translucent, and opaque formulations.
