​Electrical Insulation Precompressed Pressboard is a hard insulation board made by resin impregnated fiber substrate and high-temperature pre pressed curing, which has comprehensive characteristics such as high insulation, high flatness, compression resistance without deformation, high temperature resistance, and dimensional stability. Different from ordinary insulation boards, it has undergone pre compression densification treatment, with stronger pressure bearing capacity, less prone to delamination and bulging, suitable for working conditions that require simultaneous pressure bearing and electrical isolation. It is widely used in industries such as power, hydraulic hot press, lithium batteries, composite material forming, and testing fixtures.

The Acrylic Coated Fiberglass Sleeve is a flexible woven substrate, and the preferred methods are the grid cutting tape method and the X-cutting tape method; The pull-out method is only for research and development comparison and is not suitable for routine factory inspection; There is also adhesion verification after bending and thermal aging (industry specific judgment for casing)

​PTFE Glass Cloth Adhesive Tape, also commonly known as PTFE fiberglass tape, is made of fiberglass fabric as the substrate, impregnated with PTFE coating and high-temperature pressure-sensitive adhesive. Balancing the mechanical tensile strength of fiberglass with the low friction, anti sticking, chemical corrosion resistance, high temperature resistance, and insulation properties of PTFE, it differs from pure PTFE film tape in that it has stronger tear resistance and is widely used in various industrial production line scenarios with high temperature, adhesive, resin adhesion, friction and wear.

​ Electrical Insulation Kraft Paper belongs to the category of special industrial paper for electrical purposes. It is made from high-purity sulfate wood pulp and processed through special copying and calendering techniques. It has the characteristics of high dielectric strength, good oil absorption and impregnation performance, strong mechanical tensile strength, good flexibility, and low impurity content. It can form an oil paper composite insulation system with insulating oil and is widely used in fields such as power transmission and transformation, motor and electrical appliances, new energy, capacitors, rail transit, etc. It is the core solid insulation material inside high and low voltage electrical equipment, directly affecting the operational safety and overall service life of electrical equipment.
