Unidirectional Glass Fiber Tapes are composed of parallel continuous glass filaments with a small amount of sparse stabilizer weft yarns. Its tensile strength concentrates along the fiber axis, making it a widely used FRP material for flexural and shear strengthening of concrete beams, slabs, columns and masonry structures. Compared with fiberglass tapes for general industrial, anti-corrosion or thermal insulation applications, unidirectional glass tape for structural reinforcement has mandatory special requirements on fiber substrate, mechanical properties, alkali resistance, interfacial wetting, construction adaptability, safety certification and traceability, which directly determine the long-term structural safety of retrofitted buildings.

Ordinary crepe insulating paper is a high-resistance insulating material. It relies on cellulose to provide electrical isolation with high resistivity. Its main function is to withstand voltage and block electric current. Electrical Insulation Semiconductor Crepe Paper is blended with uniform semi-conductive fillers. It has stable medium-low surface resistivity. It does not serve as main insulation. Its core function is to homogenize electric field, shield sharp edges and eliminate concentrated local electric field. Different material characteristics define their applicable scenarios.

Unidirectional Glass Fiber Tapes is a high-performance reinforcing material widely used in structural reinforcement, wind power, pressure vessels, shipbuilding and composite manufacturing. Its mechanical properties depend heavily on proper storage. Improper storage will cause moisture absorption, aging of sizing agent, fiber delamination and reduced resin wettability, directly lowering the tensile strength of finished composite parts. There are obvious differences in storage specifications between dry unidirectional fiberglass tape and prepreg unidirectional fiberglass tape.

PVC Coated Fiberglass Sleeve is a flexible insulation pipe made of alkali free glass fiber as the base, coated with modified PVC resin on the outer layer, and plasticized at high temperature. The product combines the mechanical toughness of glass fiber with the insulation, corrosion resistance

​Electrical Insulation Precompressed Pressboard is a solid insulation support material for oil immersed power transformers and reactors, mainly used for load-bearing insulation structures such as winding end pressure plates, insulation pads, and support bars. The core process that determines its high mechanical strength, low compression creep, and excellent electrical insulation performance is the preloading process. Below is a detailed explanation of the pre pressing process principle, complete process, and process control points of the electrical insulation pre pressing plate.

​Polyimide Film For Motor Coil Winding is a premium high-temperature electrical insulation material for motor coil winding. With long-term thermal resistance at 220°C, excellent dielectric strength, partial discharge resistance and chemical stability, it is widely adopted as slot liner, turn-to-turn insulation and phase insulation for stators and rotors. It is mainly deployed in industries with high temperature, high voltage, high-frequency pulse and heavy vibration operating environments.
