SERIES COMPARISON
Read the conditions alongside the numbers.
| Series | Tube voltage | Geometry | Areal weight kg/m² | Thickness mm |
|---|---|---|---|---|
| SUM | 80–100 kV | Narrow / 窄束 | 1.3 / 1.95 / 2.6 | 0.33 / 0.51 / 0.66 |
| UM | 70–110 kV | Narrow / 窄束 | 1.40 / 2.10 / 2.80 | 0.36 / 0.54 / 0.72 |
| NPL | 60–110 kV | Broad / 宽束 | 1.45 / 2.12 / 2.83 | 0.36 / 0.51 / 0.71 |
| IEC NPL | 60–150 kV | Broad / 宽束 | 1.5 / 2.10 / 3.0 | 0.36 / 0.54 / 0.74 |
| MS-A | 90–110 kV | Narrow / 窄束 | 1.5 / 2.25 / 3.0 | 0.39 / 0.58 / 0.78 |

Each set of three values corresponds to 0.125 / 0.175 / 0.25 mmPb. Source: Medical X-Ray Shielding Core Material, page 2, version 2509. Different beam conditions are not directly rankable; confirm test standards and order requirements.
01 / PRODUCT INSIGHT
From material to application.
Six flexible, lead-free material series give protective garment manufacturers a choice of beam range, construction and areal weight. The catalog also describes the core as latex-free. Select a series against the finished garment’s intended test conditions, rather than comparing lead-equivalence labels alone.
Single- and bilayer choices
NPL and IEC NPL are described as bilayer lead-free materials. SUM and UM share the catalog’s lightweight lead-free category; MS-A and ML provide further formulation choices.
Shared roll specifications
Listed hardness is Shore A 70 ± 2. Width options are 1200, 1220 and 1380 mm, with 15 or 20 m roll lengths. Confirm the available combination for the selected series.

Where it fits
- Protective garment core materials for medical X-ray applications.
- OEM development where flexibility, total garment mass and layer arrangement must be balanced.
04 / SELECTION QUESTIONS
A closer look at your specification.
Can different series be compared by weight alone?
No. SUM, UM, NPL, IEC NPL, MS-A and ML are listed under different beam ranges and geometries. Compare weight only after matching radiation quality, lead equivalence and measurement method.
Does the catalog’s comparison image replace a test report?
The page-2 image illustrates five nominal 0.25 mmPb samples. It does not supply a complete comparative test protocol; use model-specific reports for engineering acceptance.
