Application of TPU materials in sealing rings.
Sealing rings are also called gaskets and sealing gaskets. They are usually used in machines, thermos cups, etc. It is an annular cover composed of one or more parts, fixed on a ring of the shaft and bearing, in contact with another ring or gasket, or forming a narrow labyrinth gap to isolate oil and gas, prevent oil from overflowing or passing, and prevent foreign matter from intruding. At the same time, it can also bear pressure, and has the dual functions of pressure bearing and sealing within a certain range.
1. The sealing ring should have good sealing performance within the working pressure and a certain temperature range. The sealing ring made of TPU material can automatically improve the sealing performance as the pressure increases.
2. The friction between the TPU sealing ring device and the moving parts should be small, and the friction coefficient should be stable.
3. The TPU material sealing ring has strong corrosion resistance, is not easy to age, has a long service life, good wear resistance, and can automatically compensate to a certain extent after wear.
4. The structure is simple and easy to use and maintain, which makes the sealing ring have a longer service life.
| (1) Hardness |
| TPU hardness is usually measured by Shore A and Shore D hardness testers. Shore A is used for softer TPU, and Shore D is used for harder TPU. TPU has a wide hardness range, from Shore A60 to Shore D80, which spans the hardness of rubber and plastic. The hardness of TPU is related to many properties. As the hardness increases, the following properties of TPU change. The tensile modulus and tear strength increase, the rigidity and compressive stress (load capacity) increase, the elongation decreases, the density and dynamic heat generation increase, and the environmental resistance increases. |
| (2) Tensile strength and elongation |
| The tensile strength and elongation of TPU are much better than those of polyvinyl chloride plastics and rubber. In addition, TPU does not require or adds very little additives during the processing process, which can meet the requirements of the food industry. This is also difficult to achieve with other materials such as PVC and rubber. |
| (3) Density |
| The density of TPU is approximately between 1.10 and 1.25. At the same hardness, the density of polyether TPU is lower than that of polyester TPU. |
