3M™ Nextel™ 440 Ceramic Sleeving Supplier & Exporter in India
Premium 3M™ Nextel™ 440 Ceramic Sleeving
Marshall Packings & Insulations Industries is a trusted supplier and exporter of 3M™ Nextel™ 440 Ceramic Sleeving, a premium braided ceramic sleeving manufactured from 3M™ Nextel™ 440 continuous alumina-boria-silica ceramic fibers. Designed for continuous high-temperature applications up to 1300°C (2372°F), this flexible sleeving provides outstanding thermal insulation, flame resistance, electrical insulation, oxidation resistance, and long-term mechanical durability.
Manufactured in BS-40 braided sleeving construction using 1000 denier 3M™ Nextel™ 440 plied yarn, the sleeving maintains excellent flexibility and dimensional stability even after prolonged exposure to elevated temperatures. Its non-combustible, chemically resistant, and electrically insulating properties make it suitable for aerospace, industrial furnace, power generation, and high-temperature processing applications.
It is ideal for protecting cables, wires, hoses, thermocouples, heater wires, and other components exposed to severe thermal environments.
3M™ Nextel™ 440 Ceramic Sleeving is a high-performance braided ceramic insulation product engineered for extreme thermal environments. Its flexible tubular construction provides reliable protection against high temperatures, flame, oxidation, thermal shock, and mechanical abrasion.
The sleeving combines excellent thermal insulation and dielectric properties with dimensional stability and long-term durability, making it suitable for demanding aerospace, electrical, industrial furnace, metal heat-treatment, and thermal protection applications.
