Introduction of PMI Foam Core

PMI Foam is a cross-linked rigid foam material with polymethacrylimide as the matrix. Its main molecular chain is C-C chain, and the molecular side chains contain imide structure. It has a high-performance matrix material and uniform and dense cells. The structure gives PMI foam excellent structural stability and excellent mechanical properties. PMI foam is the highest-performance sandwich material at the same density.

Features of PMI Foam Core

Thermoset Foam: PMI foam is a high-performance thermoset material with isotropic strength (equal strength in all directions).

Electrical & Wave Properties: Non-conductive, transparent to electromagnetic waves, can be formulated for wave absorption and flame retardancy.

Customizable Porosity & Density: Foam cell size is controlled by formula; ultra-fine pores are available for applications like 32–40 kg/m³ fishing floats.

Density Range: 32–300 kg/m³ (common densities: 52, 70, 75 kg/m³), special densities customizable, MOQ 10 m³.

High-Temperature Resistance: Certain PMI foam grades withstand up to 200°C, suitable for aviation and aerospace applications.

Absorption Property: PMI foam is slightly water-absorbent, a consideration for specific applications.

Production Process of PMI Foam Core

The production of PMI foam employs a precisely controlled process:

1. Liquid batching and mixing are carried out.

2. The mixture is poured into molds, which are placed in a water tank and heated via water bath to foam and form the blank.

3. The blank undergoes pre-treatment heating in an oven.

4. The blank is transferred to a high-precision oven for final foaming.

5. The blank is sent back into the oven for post-treatment.

6. Finally, it undergoes flattening via a press and is sliced.

The entire process is mechanized and combined with manual inspection to ensure stable product quality.
