Epoxy fiberglass laminate sheet

Also known as 3240 epoxy phenolic fiberglass cloth laminate, the color is yellow and black. This product is made of alkali-free glass fiber cloth for electricians impregnated with epoxy phenolic resin and baked and hot pressed. The product has high mechanical and dielectric properties, good heat resistance and moisture resistance, and good machinability. The heat resistance grade is Class B. It is suitable for insulating structural parts in motors and electrical equipment, and can be used in humid environments and transformer oil.

Board size: 1020*2020 mm, 1220*2020mm, 1220*2470mm, 1220*1220mm, 1020*1020 mm

Electrical insulation bakelite

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

Features: Good electrical properties 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 largest industrial laminate in the world.

Application: Used for motors and electrical equipment with high mechanical performance requirements and insulating structural parts. It has good mechanical strength and is mainly used in the processing of insulating parts in ICT, ITE jigs, test jigs, silicone rubber key molds, jig plates, mold splints, table grinding pads, packaging machines, combs, etc.

The difference between epoxy board and bakelite:

Epoxy board refers to epoxy resin board reinforced with glass fiber,

Bakelite is phenolic plastic board,

The strength of epoxy resin board is much higher than bakelite,

Bakelite has low toughness, poor elasticity, brittleness and cannot be used as a bow arm.

1. The price difference is not big. Epoxy board is 23 to 43 yuan/kg, while bakelite is around 19 to 57 yuan/kg.

2. The shrinkage rate is related to the composition and processing method of the resin.

3. In addition to the price and raw material advantages, bakelite has no advantages, and epoxy board is still easier to use.

Epoxy resin board is synthesized by epoxy resin and glass fiber cloth under high pressure, and bakelite board is pressed by phenolic formaldehyde, some powder and cotton cloth, so epoxy board is not as good as bakelite board in terms of performance. Bakery board has higher physical processing performance than epoxy board.
