Explore SpecificationsIn high-radiation environments, particularly those involving active nuclear fission, research accelerators, and high-energy medical therapy equipment, mitigating neutron radiation is a critical safety challenge. Standard radiation shielding materials like lead, steel, or heavy concrete are effective against gamma rays but perform poorly against neutrons. 30% Borated PE Sheet has emerged as the premier polymer composite engineered specifically to resolve this vulnerability by combining hydrogen-rich polyethylene with boron compounds.
Polyethylene matrices (whether UHMWPE or HDPE) contain a dense concentration of hydrogen atoms. Because hydrogen nuclei (protons) have a mass similar to that of neutrons, collision events between fast neutrons and hydrogen nuclei are highly elastic. This energy transfer process is known as neutron moderation, which rapidly thermalizes (slows down) fast-moving neutrons. However, once slowed, thermal neutrons must be permanently captured before they collide with other nuclei and trigger secondary gamma emissions. This is where Boron comes in.
Adding 30% Boron (by weight) dramatically increases the material's thermal neutron capture cross-section. The Boron-10 ($^{10}\text{B}$) isotope readily absorbs thermalized neutrons, undergoing a fission reaction that yields non-radioactive alpha particles and easily shielded low-energy lithium ions. Tianjin Beyond Technology Development Co., Ltd. specializes in uniform distribution of this 30% boron payload within UHMWPE and HDPE structures, ensuring zero weak spots or "neutron leakage corridors" across the entire surface of the sheet.
Provides the perfect balance between slowing down fast neutrons and immediately capturing them.
Ideal for replacing massive concrete blocks with compact polymer shielding in confined spaces.
"Increasing the boron content to 30% is a complex metallurgical and polymer chemistry process. It represents the upper tier of commercially available boron-loaded sheets, requiring advanced compression molding to prevent agglomeration."
When selecting shielding materials, physical integrity, temperature resistance, and boron density must be calculated. The table below represents standard testing variables comparing standard PE with different grades of Boron loadings.
| Polymer Composite Grade | Boron Content (wt%) | Hydrogen Density ($10^{22}$ atoms/cm³) | Specific Gravity (g/cm³) | Thermal Neutron Shielding Rate | Primary Industrial Applications |
|---|---|---|---|---|---|
| Standard UHMWPE (PE1000) | 0% | ~7.8 - 8.2 | 0.93 - 0.97 | Negligible | Chute Liners, Dock Fender Pads, Crane Outriggers |
| 5% Borated PE Sheet | 5% | ~7.2 - 7.5 | 1.02 - 1.05 | Moderate (~85%) | Standard Medical Vault Doors, Mobile Waste Casks |
| 10% Borated PE Sheet | 10% | ~6.8 - 7.1 | 1.08 - 1.12 | High (~92%) | Nuclear Power Plants, Marine Propulsion Rooms |
| 30% Borated PE Sheet | 30% | ~5.5 - 5.8 | 1.19 - 1.25 | Extreme (>99.2%) | Fusion Research, Military Accel., Spacecraft Shielding |
Founded in 2015, Tianjin Beyond Technology Development Co., Ltd. has established a comprehensive manufacturing base of approximately 50,000 square meters. Integrating heavy industrial compression molding and high-throughput extrusion lines, we specialize in high-performance polymer products. We are a regular material partner with global chemical brands like TICONA (Celanese), LG, and Sinopec.
Our core production capabilities for 30% Borated PE Sheets rest on our thermal compression system. Standard extrusion is often unable to process polymer mixtures with a solid additive phase of 30% without introducing voids. Beyond’s dedicated compression molding process applies high-pressure sintering, allowing the molecules of UHMWPE or HDPE to fuse uniformly around the microscopic boron particles.
High-quality engineering polymers require high-quality feedstock. While Tianjin Beyond Technology specializes in engineering plastics like UHMWPE and Borated PE, we maintain relationships with chemical feedstock and natural raw material providers. The strict processing standards applied to our plastic polymers also guide other divisions of our industrial operations.
Our Quality Control process includes raw material testing, structural checks, density tests, and COA generation. We manage raw material selection strictly, ensuring that the heavy polymers entering our sintering workshops meet uniform molecular weights. This allows us to guarantee that there will be no degradation of shielding performance when the sheets are exposed to active operational environments.
Premium products come from high-quality raw materials. Ya'an Times Biotech Co., Ltd. is located in Ya'an, Sichuan, where the altitude varies greatly from 525 meters to 7555 meters. The diverse landforms and ambient temperatures provide a proper growth environment for a large number of plants which are main sources of high-quality pure natural raw materials of our products.
The raw material oils used in the production of essential oils, food and cosmetics are the second largest category of our products, such as camellia oil, eucalyptus oil, turmeric oil and pepper oil, etc. Times Biotech selects high-quality raw materials with high standards, strictly controls and supervises the whole production and extraction process, and adopts strict inspection standards to guarantee our oils to be the premium raw material oils which can be your best choice for your products.
We work with international inspection bodies to maintain our certifications. Here are some of our official certificates:
Because neutrons carry no electrical charge, they easily pass through most materials. Shielding requires a composite material that can both slow down and capture these particles. 30% Borated PE is used in several demanding industries:
Cancer centers utilizing linear accelerators (LINAC) generate high levels of thermal neutrons as secondary radiation. 30% Borated PE is laminated inside heavy sliding doors, access hatches, and walls. It provides thin, effective neutron attenuation that helps keep treatment centers compact and safe.
Spent nuclear fuel elements and radioisotopes generate significant neutron fluxes during storage and transit. 30% Borated PE sheets are CNC-machined into protective gaskets, lining inserts for dry storage casks, and transport boxes, shielding logistics personnel during handling.
Advanced physics research facilities, cold-neutron source guides, and military defense shelters use Borated PE to line walls and diagnostics equipment. Its high chemical resistance, zero water absorption, and resistance to environmental stress cracking make it suitable for high-vacuum, low-temperature systems.
In addition to 30% Borated PE, Tianjin Beyond offers a range of customized engineering plastics designed for demanding industrial environments. Below is a breakdown of our materials and their typical applications:
Ultra-High Molecular Weight Polyethylene offering excellent wear resistance, impact durability, and self-lubrication. Ideal for hopper liners, guide rails, and wear strips.
High Density Polyethylene sheets designed for chemical storage tanks, cutting boards, and ground protection mats. Offers high weldability and chemical resistance.
Sustainable polymer sheets combining recycled material matrices with high structural performance, lowering carbon footprint without sacrificing mechanical properties.
These sheets can replace steel or aluminum components, offering weight savings and reducing friction in conveyor and industrial applications.
Thick-section polymer blocks designed for machining into complex components. Suitable for wear pads, machine rails, and custom shielding parts.
Procuring radiation shielding materials requires strict quality control, as material inconsistencies can lead to safety hazards. Global buyers look for verified manufacturers that can guarantee consistent boron distribution and provide complete documentation.
Boron particles must be evenly dispersed throughout the polymer matrix. If the particles agglomerate, it can leave areas with lower boron content, allowing neutrons to pass through. Our compression molding process is designed to ensure even dispersion across every sheet.
Radiation shielding structures often require precise tolerances to prevent radiation leakage through joints. Beyond’s CNC facility can machine interlocking step-joints, tongue-and-groove profiles, and mounting holes to match CAD designs.
We provide full batch documentation, including density values, chemical assays, and dimensional inspection reports. This paperwork is essential for regulatory compliance in medical and nuclear installations.
"Tianjin Beyond operates on the principle of Quality + Speed + Service = Value. We perform inspections at every stage—from raw material receipt to final packaging—under our ISO 9001 quality system, ensuring that all products meet our technical standards before shipment."
As nuclear technology and radiation therapies evolve, the requirements for shielding materials are changing. We track several key trends in the industry:
Modern medical radiotherapy vaults require protection against both neutrons and gamma rays. This has led to the development of hybrid panels. By combining a 30% Borated PE layer for neutron moderation with a lead-filled polymer layer for gamma attenuation, manufacturers can create single-panel solutions that simplify installation.
While 5%, 10%, and 30% are standard concentrations, research is ongoing into loadings up to 40% and 50%. This requires specialized processing to maintain the physical strength of the PE matrix when high levels of dry boron powder are added.
Environmental standards such as RoHS and REACH are increasingly applied to building materials, including radiation shielding. Modern borated sheets must be manufactured without hazardous plasticizers or processing aids, making them easier to handle and recycle at the end of a facility's lifecycle.
Did you know? Thermal neutrons captured by Boron-10 undergo a localized reaction, releasing an alpha particle ($^4\text{He}$) and a Lithium-7 nucleus ($^7\text{Li}$). The reaction does not produce long-lived radioactive waste, making borated polymers a clean shielding option.
Here are answers to common technical queries from nuclear engineers, radiation specialists, and procurement managers regarding the selection, machining, and performance of 30% Borated PE sheets.
A higher boron concentration (30% by weight) increases the material's thermal neutron capture cross-section. This allows for thinner panels, making it suitable for applications where space is limited, such as clinical radiation vaults, mobile shielding doors, and transport containers.
While concrete is effective, it is heavy and requires thick walls. 30% Borated PE contains a high concentration of hydrogen and boron in a lightweight polymer, allowing for thinner, lighter shielding panels. It also does not crack or degrade under structural stress like concrete.
Elemental boron has a higher concentration of active boron atoms per unit volume, which provides better shielding efficiency but is more expensive. Boric acid is a cost-effective alternative that works well for applications with moderate neutron exposure.
We use high-intensity mixing systems to coat the PE resin particles before compression molding. We then inspect the sheets using density checks and spectroscopic analysis to ensure the boron is evenly distributed throughout the sheet.
Polyethylene is a thermoplastic with a continuous operating limit of about 80°C to 90°C. For higher-temperature environments, thermal barriers or alternative polymer matrices may be required to maintain structural integrity.
Yes. Although the high boron content is abrasive to tools, the material can be machined using carbide-tipped tools and CNC routers. We offer pre-machined parts to meet customer specifications, reducing waste and tool wear on-site.
