polyurethane billets for sealing are widely used in daily production and life. It can be said that seals are used in many ways. Seals, for example, play an important role in the operation of instruments. In order to prevent foreign matter from entering, it is necessary to use seals in the machine. But there are many varieties of seals. Sometimes we need custom polyurethane billets for sealing. Now let's take a look at the reasons for this.
Reasons for custom polyurethane billets for sealing:
- According to the usage, the polyurethane billets for sealing can be divided into acid-resistant seals, alkali-resistant seals, high-temperature-resistant seals, low-temperature-resistant seals and oil-resistant seals, etc. Many machines cannot work without seals. For example, the oil seal. If there is no oil seal, oil may leak, and even cause the machine to fail to work.
- In different working environments, seals for different purposes should be selected. Such as high and low temperature environment, acid and alkali solution, oil resistance, etc. Different materials should be selected for seals working in different environments, such as the high temperature resistance of fluororubber. Therefore, we can customize seal products for flexible application.
- In addition, sometimes the hardness of the polyurethane billets for sealing is also an important factor affecting the use. Not all seals are soft, such as PTFE seals are relatively hard.
Properties of the polyurethane billets for sealing:
- Temperature environment: from -40°C to +200°C;
- Corrosion environment: acid resistance, alkali resistance, salt resistance, oil resistance, other chemical corrosion resistance, etc.;
- Wear-resistant environment: wear rate 16mm³ (DIN 53516);
- Pressure-resistant environment: tensile strength ≤ 60Mpa;
- Hardness requirements: Shore hardness ≥ 95 Shore A.
