IXPE foam is a soft and semi-rigid closed-cell foam made from polyethylene through irradiation cross-linking and foaming. The cross-linked structure improves foam consistency, resilience, tensile strength, tear resistance, cushioning performance and thermal stability.
Because IXPE foam is lightweight, low-odor, moisture-resistant and easy to convert, it is widely used as a functional material for automotive interiors, precision packaging, HVAC insulation, sports pads, medical cushioning, electronic protection, construction joints and custom industrial foam parts.
The following IXPE foam specification table helps engineers, purchasing managers and product developers compare expansion ratios, density, hardness, tensile strength, elongation, tear strength, compression set, dimensional change, water absorption and thermal conductivity.
T refers to the transverse direction, and L refers to the longitudinal direction. Custom performance can be discussed according to the final application, thickness, lamination structure and processing method.

Closed-cell structure: helps reduce water absorption and improves cushioning, insulation and protection performance.
Thermal insulation: independent cells reduce heat transfer caused by air convection, making IXPE suitable for HVAC, refrigerator, air-conditioning and building insulation uses.
Impact resistance: semi-rigid foam recovers after compression and helps protect precision instruments, semiconductors, electronics and fragile products.
Sound absorption: the closed-cell structure helps reduce noise and vibration in automotive, e-bike and industrial applications.
Excellent processability: IXPE foam can be laminated, vacuum formed, hot formed, die cut, punched, slit, engraved and bonded with other materials.
Chemical resistance: IXPE foam is odorless, lightweight, moisture-resistant, oil-resistant and acid-resistant for many industrial converting projects.
IXPE polyethylene foam is selected when buyers need a lightweight foam material with cushioning, insulation, moisture resistance and clean surface quality. It can be used as a base foam, laminated foam or custom converted foam component.

IXPE polyethylene foam is irradiation cross-linked polyethylene foam with a closed-cell structure. It is lightweight, resilient, moisture-resistant and suitable for cushioning, insulation, sound absorption, packaging and custom converted foam parts.
IXPE foam is cross-linked by irradiation, which gives the foam better cell uniformity, dimensional stability, tensile strength, tear resistance and heat resistance than many ordinary non-cross-linked PE foams.
TOPSUN can supply IXPE foam with a density range from 25 kg/m³ to 300 kg/m³. Higher-density foam is usually selected for stronger support and durability, while lower-density foam is often used for lightweight cushioning and insulation.
Yes. IXPE foam can be supplied as foam sheets or foam rolls. It can also be slit, cut, laminated, die cut, punched, engraved, molded or processed with adhesive backing according to project requirements.
The standard thickness range is 3 mm to 50 mm. Custom thickness can be discussed based on density, application, order quantity and processing method.
Yes. IXPE foam can be laminated with PE film, adhesive, fabric, aluminum foil and other materials to improve surface function, insulation performance, bonding performance or final product appearance.
IXPE foam is commonly used in automotive interiors, electronics, protective packaging, construction materials, HVAC systems, sports products, toys, medical cushioning and industrial foam components.
To choose the right grade, confirm the required density, thickness, hardness, compression performance, insulation requirement, lamination structure, surface requirement and final use environment. If you are not sure, send TOPSUN your drawing, sample or application description for recommendation.
Send your foam details to july@topsunfoam.com, including material, density, thickness, size, color, processing requirement and application. TOPSUN will review your request and reply within 24 hours.
