Introduction to gasket materials and types

Due to the fact that gaskets are made of viscoelastic materials, the initial set compression amount and rebound blocking ability will cause long-term deformation after long-term use, and will gradually lose sealing performance, leading to leakage. Long term deformation can cause the elasticity to disappear, which is also the reason why the gasket loses its sealing performance. What are the reasons why Yuantian gasket manufacturers cannot recover from deformation?
At present, there are more and more varieties of gaskets, which can be divided into various types based on their efficacy, characteristics, structural characteristics, and sealing principles, as follows:
1. Classified by structural form: rectangular frame dust washer; Fillet dust washer; Foot shaped dust washer; J-shaped dust washer; Triangle dust washer.
2. Classified by function: single function dust washer; Dual function dust washer.
3. According to whether it is framed or not: frameless dust washer; Frame type dust washer.
4. Classified by composition: single type dust washer; Combination dust washer.
