PMI foam Core & Sandwich Manufacturer
Polymethyl methacrylamide (PMI) foam is a high-performance closed-cell rigid foam core material copolymerized from methyl acrylate and methacrylonitrile. It exhibits outstanding specific strength, high-temperature resistance, and fatigue resistance, making it widely used in composite sandwich panels for aerospace, marine, rail transportation, and wind turbine blades. Composite Box offers densities ranging from 30 to 300 kg/m³.
Product Description
Polymethyl methacrylamide (PMI) foam is a comprehensive high-performance foam core material. With a density range of 30-300 kg/m³, it exhibits excellent tensile and compressive strength, particularly maintaining high mechanical property retention at elevated temperatures.
- Compared to PVC and PET foams, PMI exhibits 30-50% higher strength at equivalent densities and significantly superior heat resistance, withstanding curing temperatures exceeding 180°C in prepreg processes.
- Unlike honeycomb materials, PMI foam is isotropic, facilitating curved surface molding without moisture ingress concerns.
It exhibits balanced shear modulus and compressive strength, delivering outstanding fatigue resistance for sustained dynamic loading. PMI foam also features excellent chemical resistance, low moisture absorption, superior dimensional stability, and a high heat deflection temperature exceeding 200°C.
