The difference between 3240 epoxy glass fiber rod and bakelite:

3240 epoxy glass fiber rod refers to an epoxy resin board reinforced with glass fiber. The strength of the epoxy resin board is much higher than that of bakelite. Bakelite is a phenolic plastic board. Bakelite has low toughness, poor elasticity, and is brittle and hard. It cannot be used as a bow arm.

1. The price is not much different. The epoxy glass fiber rod is 23 to 43 yuan/kg, and the bakelite is about 19 to 57 yuan/kg.

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

3. In addition to the price and raw material advantages, the bakelite has no advantages. It is still easy to use 3240 epoxy glass fiber rod.

Epoxy resin board is high-pressure synthesis of epoxy resin and glass cloth. Bakelite board is laminated with phenolic aldehyde and some powders and cotton cloth. Therefore, 3240 epoxy glass fiber rod has better performance than bakelite board. Bakelite board is better than epoxy The glass fiber rod has high physical processing performance.
