Short Description

A pre-filled syringe is a disposable syringe that is already filled with the single dose of medication the patient needs to inject. By avoiding filling the syringe from a vial, the process is faster, easier and more accurate. It is commonly used for dental local anesthesia, vaccines, diabetes, autoimmune diseases and cancer.

Medicinal rubber plungers are widely used as primary packaging for various types of medicines. However, some relatively high-end packaging products such as prefilled syringes require rubber plunger have higher requirements for compatibility. First Rubber Company supplied products will make sure that our rubber components for prefilled syringes will meet all necessary functions.

We offer our customers integrity sealing solutions with the highest quality for their syringe systems. We are specialized to supply rubber plunger stoppers, rubber-lined aluminum seals, and needle shield for prefilled syringe.

The stopper (plunger or bung) is made of rubber that can be of different qualities and types. Today two classes of rubber are mainly used for prefilled syringes: one is chlorobutyl rubber, the other made of bromobutyl rubber.

The cap is located at the opposite end of the cartridge from the rubber plunger, and it is contained into an aluminum metal ring. The lined rubber is typically made of the same kind as the plunger rubber (usually bromobutyl rubber)

Protecting the needle from external forces is another important aspect when it comes to injectables. Both our soft and rigid needle shield that ensure the needle will not damaged during production, filling, and distribution.
