Para-aramid yarn refers to yarn made from para-aramid (poly-paraphenylene terephthalamide) fiber.
Industrial belts – commonly used varieties: (10S~60S).
Rock climbing rope – commonly used varieties: (10S~60S).
Bulletproof protection – commonly used varieties: (10S~60S).
Fire-fighting fabrics – commonly used varieties: (10S~60S).
| Line Density(English branch/S) | Breaking Strength(cN) | Breaking Strength(cN/tex) | Elongation at Break(%) | Twist Variation Coefficient(%) | Moisture Regain(%) |
| 20S/2 | ≥4100 | ≥70 | 4.0~5.5 | ≤5.5 | 4±2 |
| 30S/3 | ≥4150 | ≥70 | 3.7~5.2 | ≤5.5 | 4±2 |
Extremely High Strength: The strength of para-aramid yarn is 5-6 times that of steel wire of the same diameter, and has super tensile resistance.
High Modulus: Compared with steel wire or fiberglass, it has a higher modulus, which means it is less likely to deform even when subjected to heavy loads.
High Temperature Resistance: It can still maintain its structural stability in high-temperature environments above 560°C, without decomposing or melting.
Chemical Stability: Acid and alkali resistant, unaffected by most organic solvents, and its performance remains stable even when exposed to harsh environments for a long time.
Flame Retardant: It has very good flame retardant properties, high limiting oxygen index, is not easy to burn, and meets strict fire protection standards.
