ABRASION AND BENDING RESISTANCE

UHMWPE fibre has smooth surface and low friction coefficient thus it has better abrasion resistance compared with other chemical fibre.

TENSILE FATIGUE RESISTANCE

The woven tape made by UHMWPE fibre can maintain high strength after a thousand times of circulating load tests. This shows that UHMWPE fibre has excellent tensile fatigue resistance property.

WEATHERABILITY

UHMWPE fibre has excellent weather resistant property; it can maintain high strength and high modulus after bring exposed to sunlight for long time. Extensive tests revealed that the ultraviolet radiation property of UHMWPE Tape greatly excelled other chemical fibre,i,e.,after being exposed to sunlight for 1500 hrs, the product still keeps over 90% strength,while other chemical fibre can only keep around 40% or even lower strength.
