SPECTRA FIBER

• One of the worlds strongest and lightest fibers.
  A bright white polyethylene, that is ten to
  fifteen times stronger than steel and more
  durable than polyester, that has a specific
  strength that is 40 percent greater than Aramid
  fiber.
• Developed by Honeywell in late 1980s
• Comparable to Dyneema properties  
• Spectra is more comfortable, flexible and 40
  percent lighter material than Kevlar.

PROPERTIES

• Light enough to float (.097 Specific Gravity)
• High resistance to chemicals, water, and
• UV light
• Excellent vibration damping
• Highly flex strength
• Low coefficient of friction
• Good resistance to abrasion
• Superior breaking strength
• Susceptible to creep
• Low dielectric constant makes it virtually
  transparent to radar
