serd_3 serd_4 PLAIN-LAID POLYPROPYLENE CORE
GOST 5269-93

    SPECIFICATIONS:
  • These cores are manufactured of "polypropylene" (Russia), "gerculon" (USA), "pylen" (Japan).
  • This material has higher bending resistance than kapron but yields to it in abrasion resistance.
  • Polypropylene cores are buoyant (0.91), nonhygroscopic and have high acid, alkali and solvent resistance.
  • The disadvantages are fluidity under load and low solar radiation resistance.
  • Rope stretching under load is 8-12 %.
  • Melting temperature is 165 °C.
    APPLICATION:
  • Marine and river craft.
  • Industrial fishery.
  • In industry and construction engineering - load-lifting works
  • As tow-ropes
  • As a fiber core in steel ropes.
    RECOMMENDATIONS:
  • It is necessary to limit the working load to 15-25 % of the braking load of the core.
  • Knots of any type lead to 30-60% of strength decreasing.

Ropes arc manufactured with length at least 200 ± 10 m, only against order. It is possible, on customer's demand, to mark the cores with one color yarn. Cores arc negotiated by actual weight.
