3M™ Nextel™ 312 Ceramic Sleeving Supplier & Exporter in India
Premium 3M™ Nextel™ 312 Ceramic Sleeving
Marshall Packings & Insulations Industries is a trusted supplier and exporter of 3M™ Nextel™ 312 Ceramic Sleeving, a high-performance braided ceramic sleeving manufactured from 3M™ Nextel™ 312 continuous alumina-boria-silica ceramic fibers. Designed for continuous high-temperature applications up to 1200°C (2192°F), this flexible sleeving provides outstanding thermal insulation, flame resistance, electrical insulation, and mechanical durability.
Manufactured in AS-40 braided sleeving construction using 900 denier 3M™ Nextel™ 312 plied yarn, the sleeving maintains excellent flexibility and strength even after prolonged exposure to elevated temperatures. It is non-combustible, chemically resistant, electrically insulating, and provides reliable protection where conventional fiberglass or textile sleeving cannot withstand continuous thermal exposure.
Its conformable tubular construction makes it ideal for protecting cables, wires, hoses, thermocouples, and high-temperature components in demanding industrial and aerospace environments.
3M™ Nextel™ 312 Ceramic Sleeving is engineered for demanding thermal protection applications where high-temperature resistance, electrical insulation, flexibility, and durability are essential. The braided tubular construction provides excellent conformability and allows the sleeving to be installed over cables, wires, hoses, and other components.
With a continuous use temperature capability of up to 1200°C (2192°F), this ceramic sleeving provides reliable protection against extreme heat, flame, oxidation, and thermal cycling. Its low thermal conductivity and excellent dielectric properties make it suitable for aerospace, electrical, industrial furnace, and thermal protection applications.
