A picture to know what UHMWPE fiber is

What is UHMWPE fiber?

UHMWPE (ultra-high molecular weight polyethylene) fiber, made from polyethylene with molecular weight of 1 million to 5 million, with the highest specific strength, the highest specific modulus and the lightest specific gravity in the world, is one of the three top high-performance fibers today, which includes aramid fiber, carbon fiber and UHMWPE fiber.

Characteristics of UHMWPE fiber

♦UHMWPE fiber was first commercialized by Royal DSM N.V. in the late 1970s.
♦One of the three high-tech fibers (carbon fiber, aramid fiber and UHMWPE fiber) in the world.

The fiber has the following excellent properties:

  • Ultra high strength
  • Light weight
  • Great impact resistance
  • Great electrical insulation
  • Great thermal conductivity
  • Great chemical corrosion resistance
  • Great UV resistance

The disadvantages of UHMWPE fiber are low heat resistance (the melting temperature under stress is 145 ℃ – 160 ℃), a little poor compressibility, flammability and creep.

Synthesis technologies of UHMWPE fiber

The method of gel spinning – hot stretching has become a relatively developed industrial production technology. According to the different solvents, it can be divided into dry synthesis (ten naphthalene and other high volatile solvents, represented by DSM / Toyobo) and wet synthesis (mineral oil, white oil and other low volatile solvents, represented by Honeywell / Mitsui Chemicals).

Compared with wet spinning process, dry spinning has the advantages of short process, environmental protection and high comprehensive performance index of products.
