Even with the same Bakelite sheet, performance varies significantly. Understand the differences between paper-based and fabric-based substrates to make the optimal material selection.
【Overview】
Bakelite sheets are thermosetting resins made by impregnating and laminating phenolic resin onto a substrate, but their performance varies significantly depending on the substrate. The typical types are "paper-based substrate (paper Bakelite)" and "fabric-based substrate (fabric Bakelite)". By selecting the appropriate type according to the application, it is possible to achieve both cost reduction and performance improvement.
【Features】
Paper Bakelite uses kraft paper as its substrate and is characterized by excellent electrical insulation and dimensional stability. Its smooth surface, high uniformity, and relatively low cost make it suitable for mass production applications. On the other hand, caution is required regarding its susceptibility to impact and breakage, and performance degradation due to water absorption.
Fabric Bakelite uses cotton cloth as its substrate and boasts excellent mechanical strength and impact resistance. Its fibrous structure provides toughness, making it resistant to breakage and easy to process with tapping and complex machining. However, it is more expensive than paper Bakelite and has slightly inferior electrical insulation properties.
【Applications of Paper Bakelite and Fabric Bakelite】
Paper Bakelite is primarily suitable for electrical insulation applications, and is used as insulation boards for distribution panels and control panels, terminal blocks, and base materials for inspection jigs.
Fabric Bakelite is suitable for applications requiring mechanical strength, and is used for gears, bearing components, washers, and sliding parts.
【Industries where Paper Bakelite and Fabric Bakelite are Used】
Paper Bakelite is widely used in the electrical and electronics industries and by panel manufacturers. It is ideal for fields where a balance between insulation performance and cost is required.
Fabric Bakelite is adopted in fields such as automotive, industrial machinery, and machine tools, and is used for parts requiring impact resistance and wear resistance.
