Products Materials
Rubber diaphragms are typically made from high elasticity rubber materials such as nitrile rubber (NBR), fluoro rubber (FKM), or silicone rubber (VMQ).
Nitrile rubber is a synthetic rubber that is known for its excellent resistance to oil, fuel, and chemicals, making it a popular choice for applications in the automotive and oil industries.
Fluoro rubber, also known as FKM, has exceptional resistance to high temperatures, chemicals, and fuels. This material is commonly used in applications where extreme operating conditions are expected, such as aerospace and oil and gas industries.
Silicone rubber is known for its high temperature resistance, excellent electrical insulation properties, and good flexibility. It is commonly used in applications where a wide temperature range is expected, such as medical devices, food processing equipment, and consumer electronics.
Overall, the choice of rubber material for a diaphragm depends on the specific requirements of the application, including the type of fluid or gas being sealed, the temperature range, and the mechanical stress the diaphragm is expected to endure.
| 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 |

Functions Of Rubber Diaphragms:
1. Sealing: Rubber diaphragms are used to seal fluids or gases in pressure sensors, valves, pumps, and other devices.
2. Pressure measurement: Diaphragms can be designed to be highly sensitive to pressure changes, making them useful for pressure sensors and other measurement devices.
3. Control: Diaphragms can be used to control the flow of fluids or gases in valves and regulators.
4. Protection: Diaphragms can provide a protective barrier between different fluids or gases, preventing contamination or unwanted reactions.
5. Flexibility: Diaphragms can flex and move in response to changes in pressure or flow, making them useful in applications where flexibility is required.
6. Durability: Rubber diaphragms are designed to withstand high pressures, temperatures, and mechanical stresses, making them highly durable and reliable.
