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.

Electrical Insulation Aramid Paper is a high-performance dielectric material widely used in transformers, high-voltage motors, power batteries and electrical winding insulation. Thanks to excellent thermal stability, high dielectric strength and outstanding flame resistance, aramid paper has become an irreplaceable insulation material for high-temperature electrical equipment. However, once electrical insulation aramid paper reaches its service life, its recycling and degradation bring multiple technical and environmental challenges for power equipment manufacturers and waste treatment enterprises.

​ Polyester mica tape is a high-performance flexible electrical insulation material composed of mica paper, polyester film backing, and high-temperature resistant adhesive. It features excellent heat resistance, flame retardancy, dielectric strength, tensile stability, and moisture resistance. Compared with glass-fiber mica tape, polyester mica tape offers higher tensile strength, better flatness, smoother winding performance, and lower breakage rate during automated production.
