Process of PMI foam sandwich structure: 1. Molding process: The characteristic of the molding process is that the cost of the mold is relatively high. The advantage is that it can accurately ensure the thickness and size...
What are the commonly used composite core foams? 1. Basha wood, commonly known as balsa wood. Features: Extremely high strength and hardness (weight ratio); Specific heat is small, less affected by changes in temperature...
Performance and molding method of composite core foam: Fiber-reinforced materials are the most widely used and largest amount of composite core foam. Its characteristics are small specific gravity, large specific strengt...
Performance advantages of PMI foam packaging: PMI foam packaging has higher mechanical strength, heat resistance, solvent resistance, chemical stability, and shape stability of plastic parts than linear polymers, so in s...
Aviation aircraft requires that the materials used should be as light as possible on the basis of satisfying other properties to save fuel and increase load capacity. A sponge-like, lightweight PMI foam material has a fl...
Analysis of the characteristics of PMI foam structure: Polymethacrylimide (PMI) foam is a cross-linked rigid structural foam material with 100% closed-cell structure. Its uniformly cross-linked pore wall structure can gi...
