■Manufacturing Process of Epoxy Glass Pipes Epoxy glass pipes are manufactured using glass fiber reinforced plastic. The process begins by impregnating a cloth made of glass fibers with epoxy resin. The glass fibers coated with this resin are then dried to transform them into a material known as "resin paper." This resin paper is wrapped around a core (usually a cylindrical rod made of iron). After wrapping, it is placed in a mold and subjected to heat treatment. During this heating process, the epoxy resin cures, forming a pipe integrated with the glass fibers. Once cured, the core is removed, leaving the remaining part as the inner diameter of the pipe. The process can be likened to making taiyaki, where the core serves a role similar to that of chikuwa. The inner diameter of the pipe is determined by the dimensions of the core, but if the core is square, the inner diameter will also be square. By changing the size and shape of the core, it is possible to manufacture epoxy glass pipes of various sizes and shapes. This process results in pipes that combine the durability and lightweight properties of epoxy glass, making them suitable for a wide range of applications.

■Characteristics of Bakelite Pipes The Bakelite pipes provided by Murakami Electric Industry Co., Ltd. are lightweight yet possess thermosetting properties, allowing them to maintain stable performance even in high-temperature environments. This characteristic makes them useful in a wide range of industrial fields that require machining, thermal forming, and electrical insulation. Our Bakelite products also excel in cost performance, receiving support from many companies. Additionally, as a result of years of technological development, we are capable of manufacturing parts that require high quality and precision. Their excellent performance is particularly highly regarded in industrial applications where electrical insulation is crucial. ■Manufacturing Process and Features of Bakelite Pipes Bakelite pipes are manufactured using phenolic resin. In the manufacturing process, phenolic resin is first applied to paper, which is then dried and wrapped around a core. After that, it is placed in a mold and heated, and once formed, the core is removed to complete the product. This method allows for the free adjustment of the inner diameter size and shape.

■Characteristics of Bakelite PL-PEV Bakelite PL-PEV is a product that boasts particularly low water absorption among phenolic resin-based laminated sheets. This characteristic is especially evident when compared to the paper Bakelite PL-PEM. Since the water absorption rate varies with the thickness of the sheet, a 1mm thick sheet and a 50mm thick sheet will yield different results in weight ratio, even if the rate of water penetration is the same. This difference is evaluated based on JIS standards. Additionally, there is no cloth-reinforced Bakelite equivalent to PL-PEV, so depending on the application, paper Bakelite is used for insulation, while cloth Bakelite is used for mechanical purposes. Due to its high quality, PL-PEV is also referred to as "the top grade of Bakelite," but compared to PL-PEM, it has the characteristic that the saw teeth wear out more easily when cut with a saw.

■About the Characteristics of Bakelite Bakelite can be broadly classified into two types: paper bakelite and fabric-reinforced bakelite, each possessing different characteristics. Paper bakelite is made by applying phenolic resin to paper and curing it with heat, resulting in excellent electrical insulation properties. On the other hand, fabric-reinforced bakelite is made by applying the same phenolic resin to fabric and curing it with heat, characterized by its high mechanical strength. While paper bakelite is cost-effective, fabric-reinforced bakelite is suitable for applications that require high durability. The names paper bakelite and fabric-reinforced bakelite have been used as a long-standing convention, but the cost difference, with paper bakelite being about half the price of fabric-reinforced bakelite, is also a point to consider when making a choice. *For more details, please refer to the PDF document or feel free to contact us.
