The Development Trend Of Butyl Rubber Stopper Membrane Technology

1. The membrane has good elasticity and flexibility.
2. The membrane material should have good biological stability and biocompatibility, and undergo strict biological testing, including acute systemic toxicity testing and subcutaneous toxicity testing.
3. The film material and butyl rubber stopper are not easily detached after molding, resulting in secondary pollution.
4. The membrane material should have good isolation performance and be able to prevent the absorption of metal ions in the butyl rubber stopper.
5. It has good lubricity. Due to the movement of the butyl rubber plug during the filling process, good lubricity allows the butyl rubber plug to move on the conveying track.
6. The film material should have good thermal stability, as the butyl rubber plug undergoes different processes in different environments, such as high-pressure humid heat, dry heat, radiation radiation, etc.
