Related Introduction

The basic requirements of mechanical seal materials:

① Have certain mechanical properties, such as tensile strength, elongation, etc.;

② The elasticity and hardness are appropriate, and the compression permanent deformation is small;

③ It is resistant to high and low temperatures, does not decompose or soften at high temperatures, and does not harden at low temperatures;

④ Compatible with the working medium, without swelling, decomposition, hardening, etc.;

⑤ Good oxidation resistance and aging resistance, durable;

⑥ Wear-resistant and non-corrosive to metals;

⑦ Easy for forming and processing, and low price.
