The rubber sealing gasket basically plays a role of sealing and preventing leakage . The more common raw materials for rubber seals are NR, SBR, NBR, SIL, CR, FKM, etc. Because of the different characteristics of rubber raw materials, it may directly affect the sealing function of the seal, so it is necessary to choose the material reasonably. Rubber sealing gasket not only has the function...
Several Common Rubber Sealing Rings 1.Silicone (SIL) rubber sealing ring The characteristic of this kind of sealing ring is that it has good heat and cold resistance, and can be used stably in some places with high temperature, and it also has excellent corrosion resistance and insulation. The sealing rubber ring is often used in household appliances such as electric water heaters and microwave ov...
The working life of O-ring under dynamic pressure is 5-10 times higher than that of conventional rubber sealing products. Compared with other types of sealing rings, The O-ring has the following advantages: 1.Suitable for both dynamic and static sealing conditions; 2.Suitable for a variety of motion modes: rotary motion, axial reciprocating motion or combined motion (such as rotary reciprocating m...
The cross section of rubber seal gasket is round and has certain self-tightening effect. The sealing effect is better than the flat gasket and the compressive force is smaller. From the aspect of material, the main products of rubber pad: silicone pad, nitrile rubber pad, fluoro rubber pad, other rubber pad. Rubber pads with oil resistance, acid and alkali resistance, cold and heat resistance, agi...
In the process of storage and use of rubber, affect by the environment and human forces, the performance and appearance of rubber changes with time, which is the phenomenon of aging. So what causes rubber to age? There are mainly 7 factors as followed: 1.Oxygen: free radical chain reaction will occur between oxygen and molecules of rubber when molecular chains fracture or over cross linked, which ...
There are many kinds of rubber products, but the production process is basically the same. The basic technological process of rubber products with general solid rubber as raw material includes six basic processes: plasticizing, mixing, calendering, pressing, forming and vulcanizing. Of course, raw material preparation, finishing, inspection and packaging and other basic processes are also necessar...
