Product Description
ISO9011 Standard Phenolic Cotton Rod 10-200mm OD For High Voltage Application
Product Overview
Phenolic Cotton Rods and Phenolic Paper Rods are engineered insulation materials manufactured from cotton cloth or paper impregnated with phenolic resin under high pressure and heat. These materials offer exceptional electrical insulation properties, mechanical strength, and thermal resistance for demanding high voltage applications.
Key Features
  • Low water absorption rate for stable performance in humid conditions
  • High mechanical strength with excellent tensile and flexural properties
  • Superior electrical performance in both dry and moist environments
  • High temperature resistance (B class 130°C)
  • Excellent dielectric properties and mechanical processing capabilities
  • Good surface hardness and abrasion resistance
