High quality silicone rubber bellows

Applications:Rubber stopper or rubber plug is a plug made of rubber material and usually used to seal openings in containers or pipes. Rubber plug is generally made of natural rubber or synthetic rubber materials, with good sealing performance and wear resistance, so it is widely used in industrial, pharmaceutical, chemical, food and other industries pipeline system. Here are some of the main uses of the rubber plugs:

1. Pipe plugging: rubber plugs are widely used to seal the pipe mouth in the pipe system to prevent liquid or gas leakage.2. Sample collection and storage: In the laboratory and medical fields, rubber plugs are used to collect and store samples, such as blood, urine, drugs, etc.3. Chemical reaction: Rubber plug is suitable for sealing and leakage prevention in the chemical reaction system, such as often used in the sealing of the chemical reaction pipeline in the laboratory.4. Device protection: When the position of the device needs to be fixed in the process of machining and installation, the rubber plug can play a certain role. For example, adding rubber plug on the rotor wing plate of the air compressor can alleviate the damage caused by the extrusion shaft sleeve of the rotor wing, and play a role of shock absorption protection.5. Tool assembly: Some assembly in tool manufacturing requires rubber plugs, such as industrial brushes and bristles. In addition, some small medical devices / devices will also need to be the rubber plug.6. Gaskets: Rubber plugs can be used as gaskets to fill and prevent leakage between the two surfaces. For example, it is often used in production to fix the cork to prevent leakage.7. Other applications: Rubber plug can also be used to make racket grip handle, use waterproof belt in car exhaust pipe, etc. It can also be made with special functions of oil resistance, heat resistance, corrosion resistance and other rubber plugs.

Scope of application: Rubber plug is a widely used laboratory tool, which can effectively close the test tubes, beakers and other experimental instruments, to prevent the leakage or contamination of experimental substances. Rubber plug has a certain range of application and advantages and disadvantages, which will be detailed in this paper. The main use of rubber plug is to close the experimental instruments to prevent the leakage or contamination of experimental substances. Because the rubber plug has good sealing, it is widely used in sealing experiments, oxygen consumption measurement, volume measurement, filtration and other experiments. Rubber plugs are also widely used in laboratory biological experiments, such as cell apposition, centrifugation of cell suspensions, separation and purification of lysosomes and other subcellular structures. At the same time, rubber plugs can be used to cover unwanted parts during the experiment to prevent other substances. Advantages The advantages of rubber plug mainly have the following points: good sealing: rubber plug material hardness, good elasticity and corrosion resistance, can effectively close the experimental instruments, prevent the leakage or contamination of experimental substances. Easy to use: the size and shape of the rubber plug are diverse, and can be selected according to the size of the experimental instrument, easy to use. Economic benefit: the price of rubber plug is relatively cheap, is one of the common laboratory equipment. Disadvantages The disadvantages of rubber plug mainly have the following points: easy aging: rubber plug will lose elasticity with the passage of time, become dry and hard, resulting in a decline in sealing performance.

Property: -40ºC to  +150ºC, Aging resist, UV and O-zone resist, low and high temperature resist, corrosion resist, high loading, depending on materials
