Cross-Linked Polyethylene IXPE Foam Sheet

Cross-Linked Polyethylene IXPE Foam Sheet

TOPSUN supplies cross-linked polyethylene IXPE foam sheets and rolls for automotive interiors, electronics, packaging, construction, HVAC insulation, sports, medical cushioning and custom industrial foam parts. IXPE foam, also known as irradiation cross-linked polyethylene foam, has a closed-cell structure, smooth surface, low water absorption, lightweight performance and excellent processing flexibility.

Compared with ordinary polyethylene foam, cross-linked IXPE foam provides better dimensional stability, tensile strength, resilience, cushioning performance, thermal insulation and chemical resistance. It can be supplied in black, white and customized colors, and can be glued, printed, laminated, die-cut, punched, slit, cut, carved, molded and processed according to customer requirements.

What Is Cross-Linked IXPE Foam?

Cross-linked IXPE foam is a soft closed-cell foam material made from polyethylene through irradiation cross-linking and foaming. The cross-linked molecular structure improves foam consistency, cell stability, resilience, tensile strength, tear resistance and long-term performance.

IXPE foam combines low water absorption, light weight, shock absorption, sound insulation, thermal insulation, cushioning and odor-free performance. It is widely used in automotive interiors, sports and leisure products, protective packaging, construction materials, electronic components, toys, medical cushioning and other industrial fields.

IXPE Foam Specification

The following IXPE foam specification table helps buyers compare density, hardness, tensile strength, elongation, tear strength, compression set, dimensional change, water absorption and thermal conductivity across different expansion ratios.

T refers to the transverse direction, and L refers to the longitudinal direction. Actual product selection should be based on density, thickness, hardness, lamination structure, processing method and final application.

Key Characteristics of IXPE Foam

1. Thermal insulation: the independent closed-cell structure helps reduce heat transfer caused by air convection, making IXPE suitable for refrigerator, air-conditioning, HVAC and insulation materials.

2. Impact resistance: the semi-rigid foam structure can recover after compression and is suitable for precision instrument, semiconductor, electronic product and protective packaging applications.

3. Sound absorption: closed-cell foam can help reduce noise and vibration in automotive, e-bike, machinery and industrial products.

4. Excellent processability: IXPE has good heat resistance, ductility and even density. Vacuum forming and hot forming are also available for automotive interior and shaped foam parts.

5. Clean and durable material: IXPE foam is odor-free, lightweight, moisture-resistant, oil-resistant, acid-resistant and easy to process into different shapes or laminated structures.

Advantages of Cross-Linked IXPE Foam

• Waterproof and moisture-resistant performance for packaging, insulation and protective applications.

• Good cushioning, buffering and compression recovery for custom foam inserts and industrial parts.

• Thermal insulation and heat preservation performance for HVAC, cold chain, appliance and building materials.

• Weather resistance, aging resistance and corrosion resistance for selected indoor and outdoor uses.

• Lightweight and easy processing for roll, sheet, laminated, die-cut and molded foam products.

Applications of Cross-Linked IXPE Foam Sheet

Processing Methods of IXPE Foam

TOPSUN can convert IXPE foam sheets and rolls into custom parts according to drawings, samples or application requirements. Processing options include forming, bonding, punching, lamination and surface embossing.

• Hot press molding: place the heated material into a mold, hot press it and cool it to the required shape.

• Vacuum forming: heat the sheet or roll material, place it into the mold, evacuate the air and cool it to shape.

• Thermal bonding: heat and compound IXPE with other materials for composite foam structures.

• Punching and die cutting: punch the material into the required shape by hydraulic punching machine, CNC engraving machine or die cutting equipment.

• Lamination: use PE or other bonding layers to laminate IXPE with films, fabric, foil, adhesive or other materials.

• Embossing: press patterns onto the IXPE surface through rollers for texture or functional requirements.

TOPSUN Custom Foam Converting Capacity

TOPSUN can supply IXPE foam as sheets and rolls, and can also convert it into finished foam products for OEM projects, industrial packaging, automotive components, electronic protection and construction applications.

1. Cutting: cut foam size according to customer requirements.

2. Slicing: slice foam thickness according to required specification.

3. Lamination: hot melt film lamination, flame lamination and pressure-sensitive adhesive lamination.

4. Laser cutting: cut foam according to drawings without opening molds.

5. Die cutting: open molds according to the design for faster repeated production.

6. Compression molding: manufacture three-dimensional molded foam and foam composite parts with defined geometry and controlled wall thickness.

7. Engraving: produce tool box inserts, packaging inserts and customized foam inserts.

8. Silk-screen printing: print logos and patterns on foam surfaces.

9. Adhesive backing: apply adhesive and release liners for foam tapes and stick-on foam parts.
