3M™ Nextel™ AF-40 Fabric Supplier & Exporter in India
Premium 3M™ Nextel™ AF-40 Fabric
Marshall Packings & Insulations Industries is a trusted supplier and exporter of 3M™ Nextel™ AF-40 Fabric, a premium high-temperature woven ceramic fabric manufactured from 3M™ Nextel™ 312 continuous ceramic oxide yarn. Engineered for demanding thermal insulation applications, AF-40 Fabric offers outstanding flame resistance, oxidation resistance, mechanical strength, and long-term dimensional stability while maintaining excellent flexibility and medium air permeability. It is specifically designed to exceed the temperature capabilities of conventional glass, silica, and refractory fabrics in severe industrial and aerospace environments.
The AF-40 style features a 5 Harness Satin weave using 1800 denier (1/2 yarn), providing an excellent combination of flexibility, durability, and thermal performance. It is widely used for thermal barrier systems, furnace curtains, duct linings, expansion joints, flexible seals, composite fire barriers, Ceramic Matrix Composites (CMC), and industrial furnace insulation. Its ceramic oxide fiber construction offers excellent dielectric insulation, chemical resistance, and reliable performance during repeated thermal cycling.
