Rubber Solid Disc Washer Description
Rubber solid disc washer is a common rubber product, and the following is its related introduction:
Material
Usually, there is nitrile rubber (NBR), styrene-butadiene rubber (SBR), hydrogenated nitrile rubber (HNBR), ethylene propylene diene monomer (EPDM), silicone rubber (SILICONE), fluorine rubber (VITON), neoprene (CR), natural rubber and perfluoroelastomer (FFKM) and so on.
| Diameter | Thickness | Hardness |
| 5mm to 150mm | 1mm to 10mm | 30 to 90 Shore A |
Peculiarity
Good elasticity: It can adapt to the slight displacement and deformation between the connectors to a certain extent, play the role of cushioning and shock absorption, and reduce the wear and vibration between the components.
Good sealing: It can fill the gap between the connectors, effectively prevent the leakage of liquids, gases, and other media, and ensure the tightness of the system.
Corrosion resistance: It has a certain resistance to many chemical substances, and can maintain good performance and prolong service life in corrosive environments such as acid and alkali.
Insulation: It has good electrical insulation properties, which can be used in electrical equipment to prevent problems such as current leakage and short circuits.
Abrasion resistance: It can withstand a certain degree of friction, is not easy to wear, and ensures stable performance in long-term use.

Fields of application
Electronic appliances: It is used for sealing and damping the shell of electronic products, such as connecting internal components such as mobile phones, computers, TVs, etc., to prevent dust and moisture from entering, and to reduce the impact of vibration on electronic components.
Automobile industry: in the automobile engine, transmission, braking system, and other parts, it is used to seal oil and gas, cushion vibration, such as cylinder gaskets, oil seal gaskets, gaskets at the connection of transmission shafts, etc.
Machinery manufacturing: the connection parts of various mechanical equipment, such as bolts and nuts, flange connections, etc., play the role of sealing, buffering, anti-slip, anti-loosening, etc.
Piping system: used to connect the pipeline to prevent the leakage of liquid or gas in the pipeline, such as the flange sealing gasket of water pipe, gas pipe, oil pipe, etc.
Construction industry: There are applications in door and window installation, waterproof engineering, etc., such as door and window sealing gaskets, which can improve the sealing of doors and windows and prevent rainwater wind, and sand from entering the room.
Production process
Molding method: the rubber raw material is put into the mold, and the vulcanization molding is carried out at a certain temperature and pressure, and the gasket produced by this method has high dimensional accuracy, regular shape, and stable quality, but the mold cost is high, and it is suitable for large-scale production.
Cutting method: using a gasket cutting machine to cut the vulcanized rubber sheet into the desired shape and size, this method is highly flexible and can produce gaskets of various sizes and shapes, but the utilization rate of the plate is low, and the production efficiency is relatively low.
