Compare XPE, IXPE and IXPP foam, then choose a supply form and application route. Bofeng Foam manufactures cross-linked polyolefin foam in Zhuhai and reviews material and converting requirements against your project.
Choose the material from the constraint
XPE is chemically cross-linked polyethylene; IXPE is irradiation cross-linked polyethylene; IXPP is irradiation cross-linked polypropylene. Thin single-layer requirements point to the IXPE range; thicker cushioning, a specified contact load or a thermal constraint needs its own comparison. Density or polymer name alone does not approve a part.
Material ranges and test conditions
Factory data: density is a nominal-grade range; tolerances and ratio-specific performance are on the linked material pages. Capability ranges do not establish that every grade, thickness and facing combination is available.
| Property | XPE | IXPE | IXPP |
|---|---|---|---|
| Expansion ratio | 3–40× | 3–40× | 5–25× |
| Nominal density (kg/m³) | 26.8–300 | 26.8–300 | 40–140 (7–25× published grades) |
| Single layer (mm) | 3–15 | 0.1–15 | 1–6 |
| Heat-bonded multi-layer (mm) | 15–200 | 15–200 | 6–100 |
| Width (mm) | 500–2000 | 500–2000 | 500–1500 |
| Compression set: GB/T 6669, 23±2 °C, 22 h | Limits ≤2%–≤11%, by ratio | Limits ≤2%–≤11%, by ratio | Not published in this data table |
| Water absorption: GB/T 1034, method 4 | ≤0.2%–≤0.4% | ≤0.2%–≤0.4% | Not published in this data table |
For XPE and IXPE at 35x and 40x, the compression-set limit is ≤11%. Read each other ratio separately on its material page. No IXPP density or performance value is inferred for 5x.
Choose the delivered form
Rolls, sheets, slit rolls, heat-bonded multi-layer stock, faced laminates and drawing-based parts are different deliverables. State finished dimensions, quantity, facing, adhesive and contact surfaces. Cutting, lamination and other requested operations are confirmed for the selected base grade and construction, rather than promised for every material combination.
Temperature and functional grades
Factory literature gives IXPP a maximum service temperature up to 140 °C. That does not establish continuous use at that temperature for every grade, load or laminate. Supply continuous and peak temperatures, exposure time and dimensional limits. Flame-retardant, conductive and anti-static versions require the specific grade and applicable acceptance method; they are not properties of every standard sheet.
Use the appropriate application route
Automotive, EV battery, packaging, flooring, ESD, HVAC, sports, medical-component and marine/outdoor guides are available through the application routes below. Use the application catalogue for the current product list; this page does not maintain a separate hard-coded count. Material samples support selection, while an approved finished part needs its drawing, construction and test criteria.
Project FAQ
Can IXPP be used continuously at 140 °C?
Not on the basis of the published maximum alone. Confirm grade, load, duration and the whole construction against the actual exposure.
Where is the current application list?
Use the application catalogue linked below. Automotive and EV battery guides are also available in the Chinese language routes.
Ordering and approval
Standard rolls and sheets: MOQ 1,000 m². Custom parts: minimum quantity confirmed from the drawing. Standard lead time is 15–20 days from order confirmation; confirm the selected specification and schedule. A4 material samples are free with shipping included; converted samples, dies and fixtures are quoted separately.
Agree the material identity, drawing revision, critical dimensions, measurement conditions and required evidence before production; retain the approval record for repeat orders and review changes.
