VPBRS-02 custom color 10ml injection vial rubber stoppers

The main component of butyl rubber plug is polyisobutylene, due to the methyl group in polyisobutylene has a large three-dimensional barrier, and the thermal movement of all molecules is not active, so its permeability is lower than the elastomer, and the number of molecular double chains in the main chain is very small, so its heat resistance and heat resistance are very good, because the butyl rubber plug is unlimited. Therefore, it has a good resistance to memory solvents, and Yingyin can make Youwoo have better chemical stability. Butyl rubber has a high tensile strength, and its hardness is between 8-23.

The drugs encapsulated in the bottle stopper should enter the human body, therefore, the medicinal bottle stopper should have no pyrogen, no abnormal toxicity, no hemolytic reaction, so as to ensure the safety of the drug.

The plug should have the characteristics of convenient packaging and use, convenient and simple in clinical application. The aluminum cap of the traditional natural rubber bottle stopper needs to be scratched with auxiliary equipment, which is extremely inconvenient to use and easy to scratch the rubber plug, causing damage or pollution, while the aluminum-plastic composite cap of the butyl rubber bottle stopper only needs to gently open the plastic cap on the aluminum cap, and the rubber plug will be exposed for easy injection and use.
