Nexa3D xFLEX475-Black resin 5kg
Currently not in stock. Leave a request and we will confirm availability, price and lead time.
Nexa3D xFLEX475-Black is a single-component LSPc photopolymer that cures to a soft, rubber-like elastomer for seals, grips, midsoles and lattice structures on XiP, XiP Pro and NXE 400/400Pro.
- ✓ 44 Shore A with 150% elongation at break — genuine rubber-like flex, not a soft plastic
- ✓ 47% energy return and 7.3 kN/m tear strength for parts that snap back and survive repeated assembly cycles
- ✓ 5 kg bottle, low-viscosity single component, validated LSPc profile and water post-cure schedule included

What your process engineer actually checks
Rubber that survives the second assembly
xFLEX475-Black measures 44 Shore A with 150% elongation at break, 47% energy return and 7.3 kN/m tear strength. That combination is what gets checked on the line: soft enough to seal, elastic enough to snap back, and tough enough that seals, grips and lattice struts survive repeated assembly and demoulding cycles instead of tearing at the first stress riser.

Nexa3D xFLEX475-Black is a single-component, low-viscosity LSPc photopolymer developed with Henkel LOCTITE that cures to a soft, rubber-like elastomer — 44 Shore A with 150% elongation at break — for seals, gaskets, grips and midsoles printed on XiP, XiP Pro and NXE 400/400Pro.

Why engineers choose xFLEX475-Black
Measured values from the xFLEX475-Black technical data sheet — not the wider family marketing range.
44 Shore A, genuinely rubber-like
Shore hardness of 44 A (ASTM D2240) on a 3.7 MPa tensile modulus puts parts in true elastomer territory — they flex under thumb pressure and return to shape.
150% elongation at break
Ultimate tensile strength of 2.5 MPa at 150% elongation (ASTM D638/D412) lets seals and lattice struts stretch far past their working range before failure.
47% energy return, 7.3 kN/m tear
Rebound resilience per ASTM D2632 and tear strength per ASTM D624 give the snap-back and tear resistance that repeated assembly and demoulding cycles demand.
Low-viscosity single component
Processes at room temperature with no mixing or heating, and resists most solvents — practical for shop-floor fixtures and fluid-handling mock-ups.
How xFLEX475-Black is processed
The elastomer workflow differs from rigid resins — the water post-cure is not optional.
Print at room temperature
Shake the bottle, pour slowly into the vat and wait for a bubble-free surface, then run the validated LSPc profile on XiP, XiP Pro or NXE 400/400Pro.
Wash xClean, then brief IPA
Wash in xClean followed by IPA. Do not submerge parts in IPA for more than 5 minutes — longer soaks swell the cured elastomer and cost you dimensional accuracy.
Post-cure submerged in water
Apply a mould release and cure the part fully submerged in a transparent water container: 2 × 30 min in XiP Cure, 1 × 60 min in xCure, or 2 × 10 min at 100% in xCure Desktop.
Typical applications
Where soft-touch, snap-back and tear resistance are the governing requirements.
Physical & mechanical properties
Typical values from the Nexa3D xFLEX475-Black technical data sheet. Post-processed properties are process-dependent.

| Elongation at break | ASTM D638 / D412 | 150% (± 6.7) |
| Shore hardness | ASTM D2240 | 44 Shore A |
| Energy return (rebound resilience) | ASTM D2632 | 47% |
| Tear strength | ASTM D624 | 7.3 kN/m (± 0.7) |

Compatible printers & workflow
- Runs on Nexa3D LSPc resin systems — XiP and XiP Pro desktop printers, NXE 400 and NXE 400Pro.
- Single-component and low-viscosity: shake, pour slowly and process at room temperature, waiting for a bubble-free vat surface before the build starts.
- Wash in xClean followed by IPA; do not submerge parts in IPA for more than 5 minutes.
- Post-cure submerged in water with a mould release applied: 2 × 30 min in XiP Cure, 1 × 60 min in xCure, or 2 × 10 min at 100% in xCure Desktop. Wash and cure stations are sold separately.
- Supplied in 5 kg bottles in Black; also offered in White.
