Antistatic ESD Phenolic Bakelite Sheet Electrical Insulation Board

product details

Description

ESD Bakelite Sheet is a high-performance antistatic phenolic laminate manufactured by adding special anti-static agents during the production of traditional Bakelite sheets.

The substrate consists of phenolic resin reinforced with electrical-grade bleached wood pulp paper, providing a hard, dense, and dimensionally stable material.

This material offers uniform and permanent antistatic performance, with surface and volume resistivity maintained even after machining, cutting, or surface grinding. It is widely used in electronics, semiconductor, and precision fixture applications where static discharge control is critical.


Features

  • Extremely stable antistatic performance

  • Surface & volume resistivity: 10⁶ – 10⁹ Ω

  • Antistatic properties remain unchanged after machining

  • Good mechanical strength and rigidity

  • Intermediate electrical insulation, non-conductive

  • Resistance to organic solvents

  • Low water absorption

  • Lightweight and easy to machine

  • High temperature resistance

  • Static performance can be verified by heavy hammer test or needle tester


Applications

  • Mobile phone and electronics test fixtures

  • SMT technology countertops and work surfaces

  • PCB drilling boards and ICT fixtures

  • Semiconductor test fixtures and crystal manufacturing equipment

  • Wafer processing jigs

  • Sensitive electronic component handling tools

  • Hard disk drive manufacturing fixtures

  • High-precision automated fixtures

  • Distribution boxes and electrical panels

  • Molding machines, drilling machines, and grinding table pads

  • Electrical insulation components for motors, generators, transformers, and inverters

  • Gears, bases, baffles, pads, and structural insulation parts
