Uhmwpe sewing thread has excellent corrosion resistance due to its simple chemical structure.
Products made from this fiber will not lose their strength due to contact with acids, alkalis, polluted sea water, etc.
UHMWPE fiber has high molecular orientation and crystallization, and has good solvent resistance.
UHMWPE fibers are immersed in a variety of media, such as water, oil, acid and alkali solution for half a year, the strength is not affected.
UHMWPE fiber retains its original strength and is resistant to biological corrosion after soaking in water for 2 years.
UHMWPE fiber macromolecular chain does not contain any aromatic ring, amino, hydroxyl or other chemical groups vulnerable to attack by active reagents, and has high crystallinity, so its strength is maintained above 90% in various caustic environments, while aramid decreases greatly in strong acids and strong alkalis.
Uhmwpe sewing thread, UHMWPE, UHMWPE, is the thread with the highest strength ratio and modulus ratio in the world.
Wear resistance:
The wear resistance of materials generally decreases with the increase of modulus, but the opposite is true for UHMWPE fibers.
This is because of the low friction coefficient of the fiber, so it has a high durability.
The breaking cycle n of UHMWPE fiber rope is 8 times higher than that of arylon fiber, and the wear resistance and bending fatigue of UHMWPE fiber rope are higher than that of aranthus fiber, so it is suitable for making rope.
Light resistance:
Compared with aramid fiber, the breaking strength of UHMWPE fiber still has a high retention rate under long-term illumination.
Aramid fiber is not resistant to ULTRAVIOLET rays, so direct sunlight must be avoided when used, while polyethylene fiber, because of its advantages in chemical structure, is the most excellent fiber in light resistance of organic fiber. Even after 1500 hours of light, the strength retention rate of the fiber is still around 80%, while other fibers are under 50%.
Other features:
1. High strength and modulus.
The strength is more than 10 times of the same section of steel wire, the modulus is second only to super carbon fiber.
2. Low fiber density, 0.97g/cm3, floating on the water.
3. Low breaking elongation, high breaking work, strong ability to absorb energy, so it has outstanding impact resistance and cutting resistance.
4. Anti-ultraviolet radiation, anti-neutron and radiation, high specific energy absorption, low dielectric constant, high electromagnetic transmission.
5. Chemical resistance, wear resistance, long flexural life.
Physical properties:
Density: 0.97 ~ 0.98g/cm3.
It is less dense than water and can float on water.
Strength: 2.8 ~ 4N/ Tex.
Modulus: 91 ~ 140N/ Tex.
Elongation: 3.5% ~ 3.7%.
The impact energy is nearly twice as high as that of aromatic amide fiber with good wear resistance and low friction coefficient, but the melting point is only 145 ~ 160ºC under stress.
