Kuna tofauti gani kati ya karatasi ya epoxy 3240 na karatasi ya phenolic?
The main difference between 3240 epoxy sheet and phenolic sheet lies in their composition, properties, and applications. 3240 epoxy sheet is made from epoxy resin and glass fabric, offering excellent electrical insulation, mechanical strength, and chemical resistance. It's widely used in electrical and electronic industries. Phenolic sheet, on the other hand, is composed of phenol-formaldehyde resin and paper or cotton fabric. It provides good heat resistance, dimensional stability, and machining properties, making it suitable for mechanical and electrical applications. While both materials serve as insulators, 3240 epoxy sheet generally outperforms phenolic sheet in terms of electrical properties and moisture resistance.
