With the increasingly widespread application of nuclear technology, the choice of radiation protection materials directly affects equipment safety and personnel health. As a new type of composite shielding material, lead-boron polyethylene (B₄C) sheet, with its superior neutron absorption performance and environmentally friendly characteristics, is becoming the preferred protection solution for nuclear industries, medical institutions, and research institutions.

The unique advantages of lead-boron polyethylene (B₄C) sheet stem from its sophisticated manufacturing process and scientific material formulation. Jiangmen Rongyuan employs a high-temperature molding process, effectively enhancing the bonding force between boron carbide (B₄C) and ultra-high molecular weight polyethylene (UHMWPE) through high-speed stirring, kneading, and plasticizing. This deep fusion under high temperature and pressure ensures uniform distribution of boron in the sheet, thereby maximizing boron's high thermal neutron capture cross-section. The principle is that boron preferentially absorbs neutrons before hydrogen atoms undergo a moderation reaction, achieving complete neutron shielding and significantly improving protection efficiency.

As a functional composite material, lead-boron polyethylene (B₄C) sheet exhibits excellent catalytic activity and chemical stability. It has very low corrosiveness to equipment and does not cause environmental pollution, fully aligning with the current concept of green manufacturing. In terms of customization, Jiangmen Rongyuan can flexibly adjust the formula according to customer needs, with boron content precisely controlled between 2% and 50%. Furthermore, functional fillers such as boron trioxide, borax, lead powder, and lithium carbonate can be added to the sheets to meet the shielding requirements of different types of radiation, such as protection against complex fields like neutrons and gamma rays.
