Physically Crosslinked Polypropylene Foam

Physically crosslinked polypropylene foam. As well as named IXPP foam, XLPP foam. The IXPP regarding polypropylene as the main raw material, add additives. And by high-energy electron radiation cross-linked, made by high-temperature foam.

Fisrt, the product is extruded with the help of additives which is followed by the electron beam process. After the electron beam process. Second with hot oven operation the physical characteristic of the product increases by means of dilatation. So the product with a very closed-cell structure. And a smooth surface is obtained. In generally, it can be produced for different sectors in cut plate, roll, tube, extra-laminated or non-laminated forms.
