Kevlar Webbing Manufacturer Aramid Straps Supplier Make-to-Order
These two brands are belong to DuPontTM. They are most used ARAMID material, which Kevlar® is para-aramid and always has a natural color of yellow, on the other hand, Nomex® is meta-aramid and has a natural color of white.
Kevlar® has successfully emerged out as one of the ultra high-performance fiber since it’s been first introduced by Stephanie Kwolek on 1971, and was registered by DuPont as a famous para-aramid material commercial brand. This magic fiber has various amazing features: long-term working in high-temperature environment, high tensile load, low elongation.
Advanced Properties of Kevlar® | Para-Aramid fiberHigh strength to weight ratio
Low elongation to break
Low thermal shrinkage
Good heat & flame resistance
Self-extinguishing flame retardant properties
Good chemical resistance
Excellent bulletproof/ballistic properties
High cut resistance (not so easy to cut off than normal fibers)
UV resistance good (ONLY on black and other non-natural color fiber)
UV resistance poor (natural, and please notice this is the MAIN WEAKNESS of aramid fiber)

Sanmau produced high-performance Webbing is a critical component in protective flame-resistant clothing, harnesses, and helmets required for aerospace, military, first responders, tactical and industrial safety equipment and Personal Protection Equipments (PPE). The protective area includes physical, electrical, heat, chemicals, biohazards, and airborne particulate matters.
For complicated working conditions, ordinary materials are more and more replaced by aramid, UHMWPE, PBO fibers. With these advanced fibers, we managed to develop a series of textile which includes sewing thread, string, rope, straps, webbing, and fabric. Here’s the table of specifications of various materials:
