Washers are mechanical components placed between a bolt, nut, or screw and the surface it is fastened to. Nylon and Teflon (PTFE) washers are specialized types of washers made from high-performance synthetic materials, each with unique properties suitable for specific applications.
Nylon Washers
Features:
- Material: Made from polyamide, commonly known as nylon.
- Durability: Lightweight yet strong.
- Low Friction: Reduces wear on fastened surfaces.
- Electrical Insulation: Provides excellent non-conductive properties.
- Corrosion Resistance: Resistant to chemicals, oils, and solvents.
- Temperature Range: Can withstand moderate temperature ranges (-40°C to 100°C).
Applications:
- Electrical Insulation: Prevents metal-to-metal contact in electrical systems.
- Automotive: Used in vibration damping and noise reduction.
- Plumbing: Common in fixtures requiring chemical resistance.
- Electronics: As spacers or insulators in circuit boards.
Teflon (PTFE) Washers
Features:
- Material: Made from polytetrafluoroethylene (PTFE), a highly versatile fluoropolymer.
- High Temperature Resistance: Can withstand extreme temperatures (-200°C to 260°C).
- Low Friction Coefficient: Reduces wear and enables smooth movement.
- Chemical Resistance: Unaffected by most chemicals, solvents, and acids.
- Non-Stick Properties: Prevents adhesion of contaminants.
- Electrical Insulation: Excellent dielectric properties.
Applications:
- Chemical Industry: Used in environments with aggressive chemicals.
- Food Processing: Complies with FDA standards for non-contaminating surfaces.
- Aerospace: Withstands high temperatures and pressure variations.
- Mechanical Seals: Ensures minimal wear in moving parts.
