Dry Para Aramid Pulp

Aramid fiber characteristics

Aramids share a high degree of orientation with other fibers such asultra high molecular weight polyethylene, a characteristic that dominates their properties.

General

• good resistance toabrasion
• good resistance to organic solvents
• nonconductive
• nomelting point, degradation starts from 500°C
• low flammability
• good fabric integrity at elevatedtemperatures
• sensitive to acids and salts
• sensitive toultravioletradiation
• prone to static build-up unless finished

Para-aramids

• para-aramid fibers such as Kevlar and Twaron, provide outstanding strength-to-weight properties
• highYoung's modulus
• hightenacity
• lowcreep
• low elongation at break (~3.5%)
• difficult to dye – usually solution dyed

Major industrial uses

• flame-resistantclothing(example military MIL-G-181188B suits).
• heat protective clothing andhelmets
• body armor, competing withPEbased fiber products such asDyneemaandSpectra
• composite materials
• asbestosreplacement (e.g.brake linings)
• hot airfiltrationfabrics
• tires, newly asSulfron(sulfur modifiedTwaron)
• mechanicalrubbergoods reinforcement
• ropesandcables
• wicks forfire dancing
• optical fiber cable systems
• sailcloth(not necessarily racingboatsails)
• sportinggoods
• drumheads
• wind instrumentreeds, such as the Fibracell brand
• loudspeakerdiaphragms
• boathull material
• fiber reinforced concrete
• reinforced thermoplastic pipes
• tennis strings (e.g. by Ashaway and Prince tennis companies)
• hockey sticks (normally in composition with such materials as wood and carbon)
• snowboards
• jet engineenclosures
