Red EPDM Round Rubber Bungs 90 Shore A NBR Plug Hole Solid
Custom Mold Silicone Rubber Round Stopper /Plugs/Natural NBR Plug Hole Solid
Rubber Description
The primary purpose of a rubber stopper is to prevent a gas or liquid from escaping its container during a scientific experiment. Rubber stoppers can also prevent the contamination of samples by protecting the contents of laboratory glassware from air. Last, the use of rubber stoppers allows experimenters to shake or mix solutions without spilling them.
There are many advantages of rubber stoppers for which they are extensively used across various industries, laboratories and even in homes.
Rubber Stopper Types
- Solid Rubber Stoppers- Solid rubber stoppers are generally used for beer and wine equipment. These types of rubber stopper are also handy for other projects around the house. Solid rubber stopper sizes vary from size 000 through size 15
- One-hole Rubber Stoppers- One hole rubber stops are generally used as laboratory stoppers. They are available with the rubber stopper manufacturers, generally in standard and custom sizes.
- Two-hole Rubber Stoppers- These sturdy rubber stoppers are also lab-grade corks that are used for test tubes and flasks that contain liquids. They fit tightly to and prevent any kind of chemical leaks.
Rubber Material
| Materials | ||
| NR | Natural Rubber | High tensile strength, good ductility |
| SBR | Styrene Butadiene Rubber | Uniform quality , less foreign matter but weak mechanical strength , can be mixed with NR , widely used in tire industry , shoe soles , tape , conveyor belt , etc |
| BR | Polybutadiene | |
| IIR | Butyl Rubber | Gas is less permeable and resistant to heat, sunlight and ozone |
| EPDM | Ethylene propylene Rubber | |
| CR | Polychloroprene Neoprene | Excellent heat aging, weather resistance, ozone resistance |
| XNBR | Carboxylated NBR / Carboxyl Butadience Acylonitrile | This gelatinization is rapid sulfur addition, short scorching time, short safe storage period, compared with the general NBR, excellent wear resistance, other characteristics are similar. |
| NBR | Nitrile Rubber ( Buna ) | Resistant to alcohol, it is the most common rubber raw material for oil seal and O-ring at present |
| HNBR | Hydrogenated Nitrile / Highly Saturated Nitrile ( HSN ) | Better temperature and weather resistance than NBR, similar oil resistance to NBR, used as seals for new R-134A refrigerant system. |
| PU | Polyurethane Rubber | High hardness, high elasticity, abrasion resistance are difficult compared to other rubbers, aging resistance, ozone resistance, oil resistance is also quite good, the general PU air tightness is good |
| CSM | Hypalon , Polyethylene | Good heat resistance, weather resistance, ozone resistance, acid resistance, often used for oxidation resistant drugs (except nitric acid, sulfuric acid) |
| ACM ( PA ) | Polyacrylate Rubber | It has good resistance to petrochemical oil, high temperature and weather. It is worse than general oil adhesive. It is widely used in automotive transmission system and power system seals. |
| ECO | Epichlorohydrin / Hydrin | Good oil resistance, heat resistance and ozone resistance |
| VAMAC | Vamac ( Ethylene / Acryllic ) AEM | Petrochemical oil resistance, heat resistance, weather resistance, ozone resistance are good, compared with PA has better temperature, widely used in automotive transmission system and power system seals. |
| SIL | Silicone Rubber | Tensile strength is worse than general rubber and does not have oil resistance, heat resistance, weather resistance, ozone resistance, low temperature are excellent, suitable for high and low temperature environment, and alcohol resistance. |
| FSIL | Fluorinated Silicone Rubber | Good resistance to oil, solvent and fuel oil, good resistance to high and low temperature, used in space parts, but mostly limited to static seals, its strength and wear resistance are not good. |
| FPM / FKM | Fluoro Carbon Rubber | High TEMPERATURE RESISTANCE IS BETTER THAN SIL, CHEMICAL resistance, MOST oil AND several solvents (EXCEPT KETones, LIPids), weather resistance, ozone resistance are good, cold resistance is poor, widely used in automobile, chemical plant parts |
