Engineered plastic sheets, rods, and CNC custom machined components designed for precision demanding industrial applications.
5% Borated PE (Polyethylene) Sheet is a specialized high-performance composite polymer material meticulously engineered for radiation shielding. Containing 5% elemental Boron by weight, this unique material combines the rich hydrogen concentration of pure polyethylene with the thermal neutron capture properties of boron. It serves as a lightweight, cost-effective, and highly reliable alternative to traditional heavy lead walls or thick concrete structures in environments prone to radiation hazards.
The shielding mechanism operates on a multi-stage physical principle. Polyethylene, consisting of a dense network of hydrogen atoms, excels at slowing down fast neutrons (converting them to thermal neutrons) through elastic scattering. Once thermalized, the boron atoms (B-10 isotope) within the matrix capture these neutrons with a high cross-section, minimizing secondary gamma emission compared to metallic shielding options.
The high hydrogen concentration of the PE base acts as a moderator, while the 5% boron concentration prevents the transmission of secondary thermalized neutrons. This dual-action shielding process is vital for medical linear accelerators (LINAC) and nuclear reactor maintenance tunnels.

How procurement managers and structural engineering firms source high-grade neutron shielding materials globally.
The primary procurement concern is ensuring homogeneous boron dispersion throughout the entire thickness of the sheet. Poor blending leaves localized hot spots with no neutron attenuation, raising safety risks. Tianjin Beyond employs proprietary continuous blending technology to guarantee precise 5% weight composition.
For custom lining designs, gaps between panels must be completely avoided to prevent neutron leakage. Flatness and dimensional stability are critical. Our CNC gantry routers cut sheets with sub-millimeter precision, providing interlocking shiplap or step-joints for gapless installations.
Procuring entities require complete chemical traceability, material data sheets, and certification details. Tianjin Beyond supplies comprehensive COA (Certificate of Analysis) reports, SGS raw material verification, and ISO 9001:2015 tracking profiles for every batch dispatched.
Tailored configurations engineered for specific vertical applications in high-risk operations.
Our Inspection Laboratory Overseeing Advanced Chemical Consistency
Modern linear accelerators (LINAC) used in cancer treatments emit high-energy photons that generate secondary fast neutrons. To shield both patients and staff, oncology facilities line maze doors and vault walls with 5% Borated PE sheets. These sheets are lightweight enough to be used in automated doors while providing superior thermal neutron absorption compared to bulk concrete.
In nuclear reactors, borated polyethylene is critical during maintenance outages and for spent fuel pool storage configurations. We provide heavy-duty boards used as shielding casks and wall cladding in close proximity to neutron sources, reducing radiation exposure to staff.
University laboratories and high-energy physics installations utilize borated polyethylene sheets as collimators, target areas, and detector shielding. Our ability to supply custom CNC-machined parts enables researchers to build complex, curved geometries and tight enclosures without compromise.

Our manufacturing base spans approximately 50,000 square meters and integrates compression molding and extrusion workshops, a precision CNC machining center, and a dedicated R&D facility. Outfitted with advanced international equipment—including compression molding lines, gantry CNC lathes, gantry CNC milling machines, and large-scale CNC engraving systems—we ensure consistent quality, maintain efficient production, and deliver high-precision, large-volume, and customized products that meet the highest industrial standards.
As a reliable partner, we cooperate with major polymer material giants such as TICONA (Celanese), LG, and Sinopec to source premium raw materials. Our products have earned recognition worldwide, serving clients across diverse industries.
From raw material arrival to finished product shipment, we implement strict inspections in accordance with the ISO 9001 quality management system, providing comprehensive COA (Certificate of Analysis) reports to guarantee that unqualified products never leave our factory.
Premium products come from high-quality raw materials. Tianjin Beyond has established robust research and purchasing collaborations globally. Our sister divisions, including Ya’an Times Biotech Co., Ltd. (located in the ecologically diverse, high-altitude regions of Sichuan), specialize in utilizing local resources to extract high-purity natural organic materials. Just as Times Biotech enforces strict extraction protocols to guarantee premium camellia oil, eucalyptus oil, and turmeric oil, Tianjin Beyond applies the same level of strict, scientific control and validation to the synthesis and blending of polymer matrices.
Our independent laboratory and material engineers study plastic properties, molecular orientation, and polymer additives. Working closely with research universities, our engineers have developed specialized formulations to optimize both high-density polyethylene shielding and custom-machined mechanical components.

Our products undergo rigorous testing and international certification to meet global safety and performance standards.
Next-generation polymer developments for enhanced radiation shielding and multi-spectrum environments.
Developing integrated multi-material sheets combining Borated Polyethylene with High-Z elements (such as Lead or Tungsten dust). This allows a single composite board to simultaneously shield against both neutron radiation and high-energy gamma rays, reducing the thickness and weight of shielding walls by 35%.
Traditional polyethylene-based boards are limited to operating temperatures below 80°C. Our R&D division is prototyping custom thermosetting and high-performance engineering polymer bases that can operate continuously at 150°C while maintaining the hydrogen-to-boron ratio necessary for neutron moderation.
Focusing on environmental sustainability in the nuclear lifecycle. We are designing biodegradable polymers and highly recyclable polyethylene structures that can be easily processed post-decommissioning, reducing nuclear waste volume.
