The development trend of butyl rubber stopper membrane technology
The membrane material must have good biological stability and biocompatibility, and must undergo rigorous biological testing, including acute systemic toxicity testing and subcutaneous toxicity testing.
1. The elasticity and flexibility of the membrane are better.
2. The membrane material must have good biological stability and biocompatibility, and must undergo rigorous biological testing, including acute systemic toxicity testing and subcutaneous toxicity testing.
3. The membrane material and the butyl rubber stopper are not easy to fall off after being formed and combined, resulting in secondary pollution.
4. The membrane material must have good isolation performance, which can prevent the absorption of metal ions in the butyl rubber stopper.
5. With good lubricity, due to the movement of the butyl rubber stopper during the filling process, the good lubricity allows the butyl rubber stopper to move on the conveying track.
6. The film material must have good thermal stability, because the butyl rubber stopper has to undergo different processes in different situations, such as high-pressure damp heat, dry heat, radiation rays, etc.
