High-Temperature Industrial Thread
N24L Heptaglas PTFE-Coated Fiberglass Thread
Heat-resistant fiberglass sewing thread for demanding industrial insulation and protective applications.
N24L Heptaglas Thread is a PTFE-coated fiberglass thread intended for specialised industrial applications where resistance to elevated temperatures and demanding operating conditions is important. With a nominal diameter of 0.021 inch (0.53 mm), it is designed for suitable industrial stitching and fabrication tasks involving insulation materials, filter bags, welding curtains and protective covers.
The fiberglass construction provides high-temperature capability, while the PTFE coating is intended to support thread performance and handling. Suitability depends on the complete assembly, operating environment and the manufacturer's specified service limits.
Key Features and Benefits
High-Temperature Capability
Fiberglass yarn is specified for continuous service up to 1,000°F (537°C), subject to the manufacturer's conditions and application requirements.
PTFE Coating
Features a stated nominal coating level of 12%. The coating's service temperature range should be considered separately from the fiberglass yarn's temperature rating.
Industrial Strength
Listed tensile strength of 20 lb, providing a reference for evaluating suitability for compatible industrial stitching tasks.
Nominal 0.53 mm Diameter
The nominal thread diameter helps buyers assess compatibility with the intended sewing equipment, needle and material construction.
Industrial Insulation Applications
Suitable for evaluating use in filter bags, insulation jackets, spray shields and other specialised industrial textile products.
Specialised Material Construction
Designed for applications requiring fiberglass thread rather than conventional apparel sewing thread.

Industrial Applications
N24L Heptaglas thread may be considered for compatible industrial textile fabrication and stitching applications, including:
- High-temperature industrial fiberglass filter bags
- Spray shields and protective covers
- Industrial insulation jackets and removable insulation covers
- Glasswool and rockwool insulation products
- Welding curtains and welding blankets
- Specialised industrial protective textile products
- Other compatible high-temperature fiberglass fabric assemblies
Why Choose N24L Heptaglas Thread?
Conventional sewing threads may not be suitable for specialised industrial applications involving elevated temperatures. N24L Heptaglas PTFE-coated fiberglass thread provides an option for manufacturers working with compatible fiberglass fabrics and industrial insulation products.
Its nominal diameter, stated tensile strength and coating information can help with initial product assessment. Before selecting the thread, consider the fabric construction, stitch design, sewing-machine capability, needle compatibility, thread tension and the maximum temperature the complete sewn assembly must withstand.
Selection and Handling Notes
- Confirm compatibility with your sewing machine, needle system and intended stitch formation.
- Check the complete thread's operating temperature limits rather than relying solely on the fiberglass yarn rating.
- Verify tensile strength, coating specifications and chemical compatibility with the thread supplier for critical applications.
- Use suitable handling procedures when working with fiberglass materials, as broken fibres may irritate skin or eyes.
- For fire-protection or other safety-critical products, obtain the relevant manufacturer documentation and required compliance approvals.
