Paper Phenolic

Machining Phenolic

Paper phenolic is a versatile composite material made from paper layers impregnated with phenolic resin. This economical material offers good electrical insulation properties and mechanical strength, making it a popular choice across various industrial applications.

The manufacturing process involves layering kraft paper with phenolic resin under high pressure and heat, creating a dense, rigid laminate. This process results in a material that combines good mechanical properties with excellent electrical insulation characteristics at a cost-effective price point.

Key Characteristics of Paper Phenolic

  1. Cost-Effective: More economical than glass-based laminates while still providing good performance for many applications.
  2. Electrical Insulation: Provides reliable electrical insulation properties, making it suitable for various electrical applications.
  3. Machinability: Easy to machine and fabricate with standard tooling, offering good dimensional stability.
  4. Mechanical Strength: Offers good mechanical strength for general-purpose applications, though not as high as glass-based laminates.
  5. Heat Resistance: Can withstand moderate temperatures and maintains its properties up to approximately 125°C.
  6. Moisture Sensitivity: While treated to resist moisture, it's more sensitive to humid environments than glass-based alternatives.

Paper phenolic's balance of cost, electrical properties, and ease of fabrication makes it an excellent choice for many industrial applications where extreme environmental conditions aren't a factor. While it may not match the performance of high-end glass-based laminates, its economic advantages and reliable performance make it a staple material in electrical and mechanical applications where cost-effectiveness is crucial.
