Teflon (PTFE) coated blades are primarily used to reduce friction and heat generation during cutting operations, especially when working with:

• Synthetic fabrics (polyester, nylon)

• Thermoplastic materials (PVC, vinyl, laminates)

• Adhesive-backed textiles

This is important because:

• Lower friction = smoother blade movement

• Reduced heat = prevents material melting or fusing

• Cleaner cuts = improved edge quality
