3M™ Nextel™ 312 Sewing Threads Supplier & Exporter in India
Premium 3M™ Nextel™ 312 Sewing Threads
Marshall Packings & Insulations Industries is a trusted supplier and exporter of 3M™ Nextel™ 312 Sewing Threads, engineered for stitching, quilting, and joining high-temperature ceramic textile products used in extreme thermal environments.
Manufactured from 3M™ Nextel™ 312 continuous ceramic oxide fibers and wrapped with a rayon support fiber to improve sewability, these sewing threads provide excellent flexibility, abrasion resistance, seam strength, and oxidation resistance. The rayon support fiber enhances handling during sewing and burns off during high-temperature service, leaving a durable ceramic fiber seam.
These threads are ideal for sewing Nextel™ 312 fabrics, tapes, braided sleeves, insulation blankets, thermal barriers, and refractory textile assemblies used in aerospace, industrial furnaces, power generation, petrochemical plants, and advanced thermal insulation systems. Available in AT-21 and AT-30 styles to suit different stitching requirements.
3M™ Nextel™ 312 Sewing Threads are high-performance ceramic sewing threads designed for manufacturing and joining textile insulation products intended for demanding thermal environments. Their ceramic oxide fiber construction provides excellent thermal stability, oxidation resistance, electrical insulation, and seam integrity.
The rayon support fiber improves sewability, handling, and abrasion resistance during sewing operations and burns off during high-temperature service. This leaves a durable ceramic fiber seam suitable for repeated thermal cycling and high-temperature applications.
