Butyl Rubber Plunger Stopper for Prefilled Syringe

For prefilled syringe, the butyl rubber stopper is a best choice. The medication inside the prefilled syringe is already filled before leaving the factory. Therefore, the contact time between the medication and rubber piston is usually as long as 1-3years. Consequently, the stopper needs to have excellent chemical inertness and compatibility, which is exactly what butyl rubber stoppers possess. Also, compared to silicone rubber, possess similar good chemical and biological performance, butyl rubber is more cost-effective. For detailed specifications, please refer to the table below.
