Rubber Stopper

Rubber plug is a sealing element made mainly of rubber or thermoplastic elastomer.
- **Material**: The mainstream material is butyl rubber, which is widely used in antibiotic bottles, vaccine bottles, etc. because of its excellent air tightness and strong chemical corrosion resistance; natural rubber has high elasticity but poor chemical stability, and its use is gradually decreasing; thermoplastic elastomer is an emerging material that does not require a vulcanization process, has no precipitates and is recyclable, and is suitable for occasions with high cleanliness requirements.
- **Classification**: According to the structure, it can be divided into conical stoppers, suitable for standard glass medicine bottles; T-shaped stoppers, used for sealing the infusion bag interface, with strong pressure resistance; coated rubber stoppers, with an inert coating on the surface, which can reduce the risk of drug adsorption.
- **Performance Features**: It has good sealing performance and can tightly fit the mouth of the container through elastic deformation to prevent leakage of liquid and gas. However, its temperature resistance is usually not as good as that of metal plugs, and its resistance to certain strong acids, bases or solvents is poor.
- **Application fields**: Widely used in medicine, food, chemistry, laboratories and other fields. It is often used for sealing bottled liquids, and can also be used for waterproofing of underwater equipment, buffering of mechanical equipment, etc.
- **Production process**: Generally made through mixing, vulcanization and other processes. After the rubber raw materials are evenly mixed with various additives, they are vulcanized at a certain temperature and pressure to form rubber plugs of different shapes and sizes.Centripetal Bearings,High-Quality Bearings,Industrial Bearings,Explore our premium centripetal and radial ball bearings.
