4330-2 Phenolic Glass Fiber Moulding Compound for Electrical Insulation (High Strength Fixed Length Fibers) Usage: Suitable for insulating structural parts under the conditions of stable structural dimensions and high mechanical strength, and suitable for use in humid environments, and can also be pressed and wound tubes and cylinders. Material Composition And Preparation Ribbon phenolic glass fiber molding compounds are formed by using phenolic resin as the binder, impregnating alkali-free glass fibers (which may be long or chaotically oriented), and then drying and molding to form a ribbon prepreg. Other modifiers may be added during preparation to optimize processability or specific physicochemical properties. Reinforcement: Glass fibers provide high mechanical strength and impact resistance; Resin matrix: phenolic resins give the material heat corrosion resistance and electrical insulation properties; Additives: may include flame retardants, lubricants, etc., depending on application requirements. Processing Technology 1. Pressing conditions: Temperature: 150±5°C Pressure: 350±50 kg/cm² Time: 1-1.5 minutes/mm thickness 2. Forming method: lamination, compression molding, or low-pressure molding, suitable for complex shapes of strip or sheet-like structural parts. Fields of Application Electrical insulation: rectifiers, motor insulators, etc. Especially suitable for hot and humid environments; Mechanical components: high-strength structural parts (e.g. bearing housings, gears), automotive engine components; Aerospace: lightweight, high-temperature resistant parts (e.g., aircraft interior brackets);
