The Characteristics of Meta-aramid Fiber
Heat Resistance
The mata-aramid has long-lasting thermal stability. It can be used for long hours at the high temperature of 204℃ and maintains excellent dimensional stability. It will not embrittle, soften or melt when it is exposed temporarily to high temperature of 300℃ .
Flame Resistance
With LOI≥28, The meta-aramid is inherently flame resistant. It does not self burn or melt in the room air, no combustion-supporting, and has the property of self- extinguishing. It starts to get carbonized at 400 ℃.
Electrical Insulation
The meta-aramid fiber has very good electrical insulation property. The dielectric strength of meta-aramid paper is up to 20kv/mm.
Chemical Stability
The meta-aramid fiber has a very stable chemical structure. It is resistant to most strong inorganic acid and to alkalis at room temperature.
Radiation Resistance
The meta-aramid fiber shows good resistance to α, β and ultraviolet radiation.
Mechanical Properties
The low-rigidity and high elongation of the meta-aramid makes it available for processing by conventional textile machinery. Staple fiber can be processed into a variety of fabrics and non-wovens.
Para Aramid Products
The Para aramid materials are available in forms of filament yarn, staple fiber, short-cut, pulp and so on.
Para-aramid filament solution dyed filament and staple
The para-aramid filament is available in 600 Denier ,750 Denier,840 Denier,1000 Denier, 1500 Denier,3000 Denier,6000 Denier and 9000 Denier.
Para-aramid filament
The para-aramid filament is available in 600 Denier ,750 Denier,840 Denier,1000 Denier, 1500 Denier,3000 Denier,6000 Denier and 9000 Denier.
Para-aramid Staple Fiber
The para-aramid staple fiber is cut from the crimped filament. It is available in lengths of 38mm, 51mm, 76mm with linear density of 1.5D to 4D.Due to its good properties in high strength, high modulus, heat resistance and cut- proof, it is widely used for thermal resistant nonwovens, spun yarns, covering yarns etc.
Para-aramid Shortcut
Para-aramid Pulp
The Para-aramid Pulp is made from Para-aramid filament (linear density of 1.5D). Due to its good properties in heat resistance, friction resistance, high strength, high modulus, it is widely used for friction and sealing materials, composites and aramid paper.
Main properties
High Strength and High Modulus
Due to the high hydrogen bonds, the strength of para aramid can reach up to above 28g/D. Its specific strength is 5-6 times that of steel wire, its specific modulus is 2-3 times that of steel wire or glass fiber, and its flexibility is 2 times that of steel wire while the weight is only 1/5 that of the steel wire.
High Temperature Resistance
The para aramid can be used continuously in a very wide temperature range from -196℃ to 204℃.It has no decomposing or melting at 500℃.Its tenacity remains 75% after 100hours under 200℃.
Excellent Chemical Resistance
The para aramid is acid and alkali resistant, anti-aging with good adhesive force in rubber.
