Component Specifications

Definition
A PTFE (Polytetrafluoroethylene) sleeve is a cylindrical component manufactured from PTFE polymer, designed to provide chemical resistance, thermal stability (operating range -200°C to +260°C), electrical insulation, and minimal friction in mechanical junctions. It serves as a protective barrier, seal, or bearing surface in various industrial equipment connections.
Working Principle
The PTFE sleeve operates by creating a chemically inert, non-stick, and low-friction interface between mating surfaces in a junction. Its molecular structure provides excellent dielectric properties and thermal resistance, preventing corrosion, reducing wear, and maintaining seal integrity under extreme conditions.
Materials
Virgin PTFE (Polytetrafluoroethylene) polymer, optionally filled with glass fiber, carbon, or bronze for enhanced mechanical properties. Density: 2.1-2.3 g/cm³, Melting Point: 327°C.
Technical Parameters
  • Hardness 50-65 Shore D
  • Tensile Strength 20-35 MPa
  • Temperature Range -200°C to +260°C
  • Chemical Resistance Resistant to most chemicals and solvents
  • Dielectric Strength >40 kV/mm
  • Coefficient of Friction 0.04-0.10
Standards
ISO 12086, DIN 3754

Frequently Asked Questions

What are the main advantages of using a PTFE sleeve in industrial junctions?

PTFE sleeves offer excellent chemical resistance, high-temperature stability, low friction, and electrical insulation, making them ideal for harsh environments and reducing maintenance needs.

Can PTFE sleeves be used in food processing equipment?

Yes, PTFE is FDA-compliant and suitable for food-grade applications due to its inertness and non-toxic properties.

How does temperature affect PTFE sleeve performance?

PTFE maintains properties from -200°C to +260°C, but may experience cold flow or creep under sustained load at high temperatures; filled PTFE variants can improve this.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
