It is a plastic pipe with excellent insulation properties, heat resistance, mechanical strength, and chemical resistance.
We are utilizing a wide range of applications, including insulating tubes for transformers and tap changers, rollers, bearings, and winding cores.
Inquire About This Product
basic information
It is made by applying and impregnating thermosetting resins (phenolic resins, epoxy resins) onto paper, cotton fabric, or glass cloth, and then winding this onto a steel core while heating and applying pressure. Therefore, it is called "thermosetting resin laminated pipe" (JIS K 6914). Although it is a plastic pipe, it contains reinforcing materials such as paper, cotton fabric, or glass cloth, which gives it superior strength compared to pipes made by injection or extrusion. Additionally, it also possesses the insulating properties and chemical resistance of the base resin.

Detailed information
-
Paper-based phenolic resin laminated tubes are widely used for electrical applications such as insulating tubes and insulating collars, as well as for mechanical applications such as rollers and core materials.
-
Fabric-based phenolic resin laminated tube It has excellent wear resistance, so it is used as a sliding material for piston wear rings, bearing retainers, and bearings.
-
Glass fabric substrate epoxy resin laminated tube. It excels in both electrical insulation and mechanical strength. There are also types that are flame-retardant and heat-resistant.
