Compare all 7 grades and fillsHide
| Grade · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness |
|---|---|---|---|---|---|
XPP-30 | Choose for light cushioning and insulation where minimum weight is the priority and loads are small; the 0.006 GPa modulus limits any load-bearing use. | — | 0.3 | 30 | — |
Flame-retardant grade | Pick for rail-vehicle and appliance liners required to meet UL 94 HF-1 or GB 8624 B1, usually via a halogen-free phosphorus system; service temperature is capped at 95 °C. | — | 0.55 | 18 | — |
Carbon-black conductive grade | Choose the carbon-black grade when genuinely conductive shielding packaging at 10⁴–10⁶ Ω is needed to ship sensitive devices; colour is fixed black and tensile strength falls to 0.55 MPa. | — | 0.55 | 15 | — |
Antistatic / dissipative grade | Use for electronic-component cushions and returnable-box liners that must dissipate static charge, holding 0.06 g/cm³ density and 0.6 MPa tensile strength. | — | 0.6 | 22 | — |
D60Default XPP-60 | Use as the default density for general cushioning, thermoformed liners and light sandwich cores, balancing 0.65 MPa tensile strength against a 0.015 GPa modulus. | — | 0.65 | 25 | — |
XPP-90 | Pick for heavy-duty packaging and tooling trays that need higher bearing load and dent resistance; the 0.09 g/cm³ density adds weight and cost over the standard board. | — | 1 | 22 | — |

What is XPP D130?
XPP D130 is XPP in the D130 grade — choose as a composite sandwich core co-pressed with GF/PP skins, where the 0.038 GPa modulus and shear strength are highest; 130 kg/m³ is the heaviest and least compliant option. XPP D130 has a tensile strength of 2 MPa (0.218 ksi), weaker than 85% of polymer grades. Elongation at break is 18% and the elastic modulus is 0.04 GPa (0.0055 Msi). XPP D130 has a density of 0.13 g/cm³ (0.0047 lb/in³), lighter than 86% of polymer grades. Its glass-transition temperature is -10°C (14 °F). D60 is the default condition FabDigit quotes; D130 is available on request or by drawing note.

Working with XPP D130
Is XPP easy to machine?
Hot knife or hot wire, die cutting, waterjet and high-speed CNC milling all work. For milling use sharp single-flute cutters at high spindle speed and low feed to prevent melting and chip welding.
Can XPP be welded?
PP-to-PP joints can be made by hot-plate, hot-air or ultrasonic welding. Double-sided tape and hot-melt adhesive are also used; flame or corona treatment first raises surface energy.
Can XPP be formed, bent or molded?
Sheet softens at about 150-165 C for vacuum or pressure thermoforming and can be press-laminated with GF-PP skins into sandwich panels. Unlike EPP beads it cannot be steam-molded into complex three-dimensional parts.
What surface finishes work on XPP?
Surface energy is low, so corona or plasma treatment plus a PP-specific primer is required before painting or printing. Co-extruded PP film or laminated nonwoven facings give a finished surface directly.

XPP D130 is typically used for lightweight structural core panels, thermoformed packaging trays, automotive underbody shields, construction insulation boards and reusable container panels. In short: stiffest extruded polyolefin foam; 100 C service temperature; thermoformable board stock.
What is the tensile strength of XPP D130?
XPP D130 has a typical tensile strength of 2 MPa (0.218 ksi) — weaker than 85% of polymer grades. Strength varies by condition: see the 7 listed tempers.
Is XPP D130 easy to machine?
Reasonably — machinability is rated good (68/100, better than 71% of polymer grades). Hot knife or hot wire, die cutting, waterjet and high-speed CNC milling all work. For milling use sharp single-flute cutters at high spindle speed and low feed to prevent melting and chip welding.
Can XPP D130 be welded?
Yes — weldability is rated very good (70/100). PP-to-PP joints can be made by hot-plate, hot-air or ultrasonic welding. Double-sided tape and hot-melt adhesive are also used; flame or corona treatment first raises surface energy.

What is the maximum service temperature of XPP D130?
XPP D130 is rated for continuous use to about 105°C (221 °F), and briefly to 130°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
