3M™ Nextel™ Ceramic Sleeving 312 – Style AS-40
High Temperature Alumina-Boria-Silica Protection Sleeve
3M™ Nextel™ Ceramic Sleeving 312, Style AS-40 is a high-performance braided ceramic fiber sleeve designed for extreme temperature protection, electrical insulation, and thermal shielding applications.
Manufactured using advanced Nextel ceramic fiber technology, this sleeving provides excellent heat resistance, chemical stability, and long-term durability in demanding industrial environments.
Nextel 312 ceramic sleeving is produced from alumina-boria-silica continuous filament fibers, offering superior thermal stability compared with conventional fiberglass sleeves.
The braided tubular construction allows the sleeve to expand and conform around wires, cables, hoses, pipes, and high-temperature components, providing effective thermal insulation and mechanical protection.
Style AS-40 ceramic sleeving is commonly used in aerospace systems, industrial furnaces, power generation equipment, and high-temperature electrical insulation applications where materials must withstand continuous exposure to elevated temperatures and harsh environments.
Product Overview
3M Nextel 312 AS-40 ceramic sleeving is engineered for applications requiring lightweight, flexible, and durable high-temperature insulation.
The braided sleeve structure ensures easy installation over complex shapes while maintaining reliable insulation performance under extreme heat conditions.
Unlike traditional fiberglass or organic insulation sleeves, Nextel ceramic sleeving offers higher temperature capability, superior oxidation resistance, and improved mechanical strength, making it suitable for critical thermal protection systems and high-temperature industrial applications.
