How IXPP Foam Is Manufactured
IXPP foam is produced through a controlled irradiation cross-linking and foaming process. This manufacturing method creates a uniform closed-cell structure that delivers lightweight performance, heat resistance, and excellent mechanical properties.


01 Raw Material Control & Mixing
•Consistent raw material input
Carefully selected raw materials and controlled mixing help maintain stable formulation, density, and processing consistency from batch to batch.
02 Precision Extrusion
•Stable thickness and density control
Advanced extrusion control helps ensure uniform thickness, density, and surface quality for further converting and lamination.




03 Electron Beam Cross-Linking
•Enhanced strength through cross-linking
Irradiation creates a cross-linked structure that improves material strength, thermal resistance, and long-term dimensional stability.
04 Controlled Foaming Process
•Uniform closed-cell foam structure
Precise foaming control helps create a fine and consistent closed-cell structure for cushioning, insulation, and stable performance.




05 Quality Inspection & Packaging
•Reliable inspection and packaging standards
Strict inspection and standardized packaging help ensure clean delivery, consistent quality, and dependable performance for automotive applications.
