Ultra high molecular weight polyethylene Suture
Short Description
suture woven with ultra-high molecular weight polyethylene fiber is a linear material used for human surgical suture, high material has no side effects on the human body, self-smooth, no water absorption, bending fatigue, anti-aging and many other advantages have been widely used in the medical field.
Product characteristics
High specific strength, high specific modulus. The specific strength is more than ten times that of the same section wire, second only to the specific modulus.
Low fiber density and can float.
Low fracture elongation and large fault power, which has a strong energy absorption ability, and thus has an outstanding impact resistance and cutting resistance.
Anti-UV radiation, neutron-proof and γ -ray prevention, higher than energy absorption, low permittivity, high electromagnetic wave transmission rate, and good insulating performance.
Chemical corrosion resistance, wear resistance, and long deflection life.
Physical Performance
☆ Density: 0.97g/cm3. Lower density than water and can float on the water.
☆ Strength: 2.8~4N/tex.
☆ Initial modulus: 1300~1400cN/dtex.
☆ Frault elongation: ≤ 3.0%.
☆ Extensive cold heat resistance: certain mechanical strength under-60 C, repeated temperature resistance of 80-100 C, temperature difference, and the use quality remains unchanged.
☆ The impact absorption energy is nearly twice the high of counteraramide fiber, with good wear resistance and small friction coefficient, but the melting point under stress is only145～160℃。
