What is advantage of TEFLON SEALER, .002 TO .003 THICK?

What is advantage of TEFLON SEALER, .002 TO .003 THICK?

A Teflon sealer (PTFE-based) applied at 0.002 to 0.003 inches thick offers several distinct advantages, particularly in industrial, mechanical, and chemical applications. Here are the key benefits:


1. Excellent Non-Stick Properties

  • Prevents buildup of materials like adhesives, paint, resins, or food.
  • Ideal for molds, tools, chutes, and surfaces exposed to sticky or viscous substances.

2. Low Friction / Lubricity

  • Teflon has one of the lowest coefficients of friction among solid materials (as low as 0.05).
  • Reduces wear and energy loss in moving parts.
  • Enhances sliding performance in assemblies.

3. Chemical Resistance

  • Resists almost all chemicals including acids, bases, solvents, and corrosives.
  • Useful in harsh chemical environments (e.g., chemical processing, lab equipment).

4. Corrosion Protection

  • Acts as a barrier to moisture and corrosive agents.
  • Protects metal surfaces from rust, oxidation, or chemical attack.

5. Electrical Insulation

  • Excellent dielectric properties; useful in electrical and electronic applications.
  • Prevents arcing or shorting in high-voltage areas.

6. Thermal Resistance

  • Withstands a wide range of temperatures (typically -100°F to +500°F or more).
  • Stable in high-temperature environments without degradation.

7. Thin Yet Durable

  • At 0.002–0.003 inches, it’s thin enough not to interfere with part tolerances.
  • Durable enough for moderate wear and chemical exposure.

8. Easy Cleaning / Maintenance

  • Surfaces stay cleaner, require less frequent maintenance.
  • Reduces downtime in production environments.

Typical Use Cases:

  • Fasteners (to prevent galling and seizing)
  • Food processing equipment
  • Chemical tanks or valves
  • Molds and tooling
  • Sliding components and guides
  • Electrical insulation barriers
