MarShield has 35 years of experience in the manufacturing of leaded radiation shielding products. We can advise on various materials to use and can supply any configuration for lead wool blankets to best address your requirements.

MarShield lead blankets are made using lead wool, but lead plate is available. Lead wool is the preferred material due to its flexibility in handling. It consists of fine strands of lead from .005 to .015 inch diameter, of varying length. MarShield supplies lead wool products in accordance with Federal Specification QQ-C-40 Type II Grade C. We compact this interlaced wool in a random orientation to ensure consistent attention without streaming.

MarShield offers a unique and versatile solution to shielding difficult radiation applications with flexible Lead Wool Snakes and Wraps. The tubular and flexible lead shields can be wrapped, twisted and shaped to perfectly fit any application, preventing radiation leaks. MarShield Lead Wool Snakes and Wraps can be inserted into pipes, heat exchangers, collar, holes and more.

Sizes

MarShield Lead Wool Snakes and Wraps are available in 1.5″, 2″ or 3″ diameters, and 2-8 feet lengths*.

Features:

• Herculite cover, inner and outer, high-strength and durability
• Optional high-temperature cover.
• Unique wool format eliminates loss of shielding due to lead settling or shifting.
• One reinforced grommet on one end, which eases handling and installation.

MarShield now offers an excellent alternative to lead wool shielding blankets with our T-flex product. T-Flex shielding blankets are fabricated from a proprietary blend of bismuth and iron powders optimized to provide equivalent attenuation to either a 10 lb/ft or 15 lb/ft lead wool products at approximately 50% of the weight. T-Flex lead replacement sheets are designed to provide a flexible and durable industrial grade product that will provide 20 years of service.
