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
