Be made of para aramid passed by two times twised the specs as same as fimament yarn
1. Introduction
Para-aramid fibre is a polymetaphenylene isophthalic amide fibre which exhibits high performance in many fields.
2. Propertise
Para aramid filament has outstanding performances of lightness, high strength, high modulus, anti-corrosion:
** High temperature Resistance.
** High tenacity and strength.stretch proof, tear-resistance,puncture proof , friction resistance.
** Resistance to flame.
** Resistance to Chemicals
3. Usage
** Reinforcement materials: repair and reinforcement of buildings and bridges;tyres cord fabric,tyres reinforcement; high-strength cables; optical cable reinforcement;reinforcement material of rubber hoses and belts.
** Personal protection: Bullet-proof apparels and helmets, heart-protect boards; cut proof gloves and wrist supports; high-temperature resistance gloves and apparels;sportswear.
** Composite materials: secondary structure of big airplanes;airplane cockpits and engine cowlings;radomes and antennas; yachts and vessels; automobile outer shells; fan blades; circuit boards; resin coating material.
** Friction sealing :brake facings and clutch disks; gearbox friction plates; gaskets; packings.
** Sports instruments and others: golf shafts; tennis rackets/lines; skidding instruments; racing
Para Aramid Fibers
Para-aramid fibers are very fine fibers with a very high tenacity, are nonconductive, have a low flammability and have an excellent abrasion resistance.
Para- aramid fibers and fabric by-products can be recycled into
- a milled para-aramid fiber with various fiber lengths (from 200 microns to 6 mm) for use in gaskets, brakelining,thermoplastics.
- staple fiber with a fiberlength of 40 ~60 mm for use in yarnspinning, nonwovens.
Para-aramid,the full name as poly(p-phenylene terephthalmide),is abbreviated as PPTA
The raw-aramid is called one of the three high performance fibers in the world,with carbon fiber and Ultra high modulus weight polyethylence(UHMWPE)as the othr two.It possesses outstanding properties of high strength,high modulus,high temperature resistance and flame resistance.It has advantages of relative low density,fatigue resistance,tear and shear resistance,dimension stability.It has irreplaceable position in areas like personal prosonal protection,aerospace,electrical communication,and etc.
