The difference between 3240 epoxy glass fiber board and bakelite board

The function of the bakelite board is mainly for insulation, while the 3240 epoxy glass fiber board is made of glass fiber cloth bonded with epoxy resin and heated and pressurized. It has high mechanical performance at medium temperature and stable electrical performance under high humidity. To learn more.

3240 epoxy glass fiber board, also known as 3240 epoxy phenolic fiberglass cloth laminate, the color is yellow and black. This product is made of electrician’s alkali-free glass fiber cloth impregnated with epoxy phenolic resin and baked and hot pressed. 3240 epoxy glass fiber board products have high mechanical and dielectric properties, good heat resistance and moisture resistance, and good mechanical processability. The heat resistance grade is B grade, which is suitable for insulating structures in motors and electrical equipment. Parts, and can be used in humid environments and transformer oil.

3240 epoxy glass fiber board size: 1020*2020 mm, 1220*2020mm, 1220*2470mm, 1220*1220mm, 1020*1020 mm

Bakelite board, also known as bakelite board, full name epoxy phenolic laminated board. The color is orange and black. The specification size is 3-50mm*1000mm*1220/2000mm (thickness * width * length). The bakelite board uses high-quality bleached wooden building paper and cotton linter paper as reinforcements, and is made of phenolic resin made from the reaction of high-purity, fully synthetic petrochemical raw materials as the resin binder.

Bakelite characteristics: Good electrical performance at room temperature, good mechanical processing performance, specific gravity 1.45, warpage ≤ 3‰, and excellent electrical, mechanical and processing properties. Paper bakelite is the most common laminate, and it is also the most widely used and used industrial laminate in the world.

Bakelite application: used in motors, electrical equipment and insulating structural parts that require high mechanical performance. Good mechanical strength, mainly used in the processing of insulating parts in ICT and ITE fixtures, test fixtures, silicone rubber key molds, fixture plates, mold plywoods, table polishing pads, packaging machines, combs, etc.
