UHMWPE (IZANAS®)
What is IZANAS®？
Ultra-High Molecular Weight Polyethylene (UHMWPE)
IZANAS® is yarn made from ultra high molecular weight polyethylene. and it has the highest level of strength and modulus as an organic fiber (it is about 8 times stronger compared with same weight piano wire). 10mm diameter IZANAS® rope can support up to 20 tons (theoretical value).
IZANAS® is used in various fields because of its excellent properties. A solution of ultra high molecule weight (chain of very long molecules) is spun into a quenching device, and upon cooling solidification/crystallization takes place producing a gel-like appearance due to immiscibility of solvent.As-spun filaments are transported into an oven in which super-drawing is performed at elevated temperatures.Through these process, the highly drawn fiber highly crystallized and have highly oriented molecular chain structure. Due to the structure, IZANAS® shows extremely high strength and excellent properties.
