Silicone High Precision Rubber Seal , Custom Nbr O Rings Epdm Fkm O Ring Seal Gasket
Rubber seals are a common basic element in sealing devices, which plays a very important role in the contradiction of leakage and sealing. Solve the problems of leakage and sealing in the process of mankind's conquest of nature. It has been an important way to promote technological progress and prevent and reduce environmental pollution. Rubber seals are a kind of rubber product widely used in sealing technology. Because rubber has valuable elastic polymer materials, with a wider temperature range, giving less stress in different media will produce greater deformation. This deformation can provide contact pressure, compensate for the leakage gap, and achieve the purpose of sealing.
Rubber Mateials
| 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 |

Silicone:The term silicone covers a large group of materials in which vinyl-methyl-silicone (VMQ) is often the central ingredient. Silicone elastomers as a group have relatively low tensile strength, poor tear and wear resistance. However, they have many useful properties as well. Silicone has a good heat resistance, good cold flexibility, and good ozone and weather resistance as well as good insulating and physiologically neutral properties.
