PTFE S2 Glass Sewing Thread

Crafted from high-purity, ultra-fine continuous S-2 glass filaments, all encapsulated in a uniform PTFE (Teflon) coating. This advanced coating significantly boosts the thread's resistance to thermal shock, chemical attack, and contaminant buildup. When compared to E-glass threads, S-2 glass provides approximately 30% higher tensile strength and can withstand higher maximum operating temperatures. Additionally, the PTFE coating helps sewing, abrasion resistance, and flexibility, effectively preventing issues such as kinking, stripping back, or breakage, which are often encountered with uncoated high-temperature threads.
