Para Aramid Sewing Thread

●Excellent flame retardant properties

The limiting oxygen index(LOI) is over 29%. start to carbonise and decompose above 500℃

●Excellent high temperature resistance

Can be used continuously in a very wide temperature range from -196℃ to 260℃.It has no decomposing or melting at 500℃.

●Chemical stability

Para aramid is acid and alkali resistant, anti-aging with good adhesive force in rubber;

●Good textile properties

High resistance to breakage and its high break elongation ratio guaranteed the end product with high intensity, good product longevity, and better tolerance to injection;

●No Melt Drip properties

Flame resistant with self-extinguish nature and non-melt drip characteristic.

●High Strength and High Modulus

Due to the high hydrogen bonds, the strength of Taparan®para aramid can reach up to above 28g/D.Its specific strength is 5-6 times that of steel wire , its specific modulus is 2-3 times that of steel wire or glass fiber , and its flexibility is 2 times that of steel wire while the weight is only 1/5 that of the steel wire.
