1. Material Base: UHMWPE vs. HDPE
The primary difference lies in the polymer matrix. While standard Polystone® often utilizes an HDPE base, JSLT Polymers® specializes in Borated UHMWPE (Ultra-High Molecular Weight Polyethylene). With a certified molecular weight of 8.62 million Daltons, our BPE offers superior impact strength and dimensional stability under thermal cycling compared to standard HDPE-based shielding boards.
2. Boron Content & Uniformity
Both JSLT and Röchling offer various boron loading levels (typically 5% by weight). However, JSLT's proprietary multi-stage mixing process ensures zero 'boron-settling' during compression molding. This resulting uniformity is critical for consistent attenuation of fast neutrons across the entire surface of a 200mm thick shielding panel.
| Specification | JSLT BPE-5 | Röchling Polystone® M Nuclear |
|---|---|---|
| Base Polymer | UHMWPE (8.62M) | HDPE / UHMWPE |
| Boron Content | 5% (Standard) / up to 30% | 5% (Standard) |
| Density (g/cm³) | 1.06 - 1.08 | 1.05 - 1.07 |
| Hydrogen Atoms/cm³ | ~7.8 x 10²² | ~7.6 x 10²² |
| Max Thickness (mm) | 300 mm (Factory Pressed) | Varies by region |
| Color | Natural / Purple / Dark Grey | Yellow / White / Purple |
3. The Factory-Direct Cost Advantage
Specifying Röchling often involves multiple layers of international distributors and local stockists, which can inflate costs by 40-60%. By sourcing directly from JSLT Polymers®, large-scale shielding projects can save significant budget without compromising on material certification. We provide full CTIC material test reports and boron content verification with every batch.
❓ Frequently Asked Questions
❓ What is the lead time for JSLT Borated PE?
Standard 5% BPE sheets (1220x2440mm) are typically ready for dispatch within 12-18 days from our Dezhou factory.
❓ Can JSLT machine complex BPE parts?
Yes. Our CNC workshop specializes in stepped-joint shielding panels and interlocking blocks to prevent 'neutron streaming' through gaps.
❓ Do you offer 30% Boron loading?
Yes. We can manufacture high-concentration BPE-30 for specialized aerospace and research reactor applications.
