Kevlar Piston pump seals for water

The Kevlar fiber seals rings has higher compressive strength and better tear resistance.

Kevlar fiber Mechanical properties:

Strength: 3.6 GPa

Elongation modulus: 131 GPa

Elongation at break: 2.8%

Thermal performance:

Long term use temperature: 180 ℃

Axial thermal expansion coefficient: -2 × 10 ^ (-6)/K

Thermal conductivity: 0.048 W (m · K)

Kevlar fiber characteristics:

1. Permanent heat resistance and flame retardancy, with a limit oxygen index Loi greater than 28.

2. Permanent anti-static properties.

3. Permanent resistance to acid, alkali, and organic solvent erosion.

4. High strength, high wear resistance, and high tear resistance.

5. No molten droplets are produced when exposed to fire, and no toxic gases are produced.

6. When burning the fabric surface, it thickens, enhances sealing, and does not break.
