The mechanical properties of high strength and high modulus : a strong hydrogen bond strength , strength of up to 28 g / D more, than the strength of steel wire 5 to 6 times higher than the modulus of steel wire or glass fiber 2 to 3 times, toughness steel wire are two -fold , and weighs only wire about 1/5 .     
We offer a broad range of standard and high modulus para-aramid yarns.
Para-aramid Yarn          
Para-aramid is a synthetic fiber that is resistant to heat and flames and is characterized by extreme tensile strength, impact resistance and low elongation at break. It also has good resistance to acids and alkalis.  SFT has a wide range of para-aramide in the form of high-tenacity yarns and fibers. The strength in relation to the density of the material is very high: so is the E-modulus     
The fibers are produced by polymerization and subsequent wet spinning. The PPTA polymer is dissolved in concentrated sulfuric acid and extruded through spinnerets. In the following air gap, the polymer strands in the liquid filament orient themselves to the fiber axis, which is a major factor later for the strength. Through further plugging processes, a fiber is created, which is formed from completely extended liquid crystal chains with a high degree of crystallinity. This leads to an increased fiber strength.     
Aramid Yarn           is widely used in high-end fields such as tires, optical cables, bulletproof, high-speed rail, aerospace, etc.
