High initial modulus with low elongation for outdoor long-span optical cable and tension members. The rigid molecular structure of PPTA delivers stiffness, dimensional stability and thermal resistance over long cable spans.
PF300 is a high-modulus PPTA para-aramid continuous filament yarn designed for optical cable constructions where stiffness and dimensional stability matter most — outdoor long-span designs, tension members and reinforced cable cores. Its high initial modulus limits elongation under installation and service loads, keeping attenuation stable over the cable lifetime.
Strength elements and tension members for outdoor long-span optical cable; central and peripheral strength members where low elongation and high stiffness are required; industrial tension applications.
Limiting oxygen index (LOI) 29% · decomposition temperature approx. 500 °C · density 1.44 g/cm³. The yarn does not melt.

Values shown as specification / typical. Linear density: ASTM D1907. Tensile properties: ASTM D7269 on yarn prepared at a twist multiplier of 1.1, gauge length 250 mm, test speed 200 mm/min, pre-tension 0.2 gf/den. Oil pick-up: ASTM D2257. Conditioning: 21 ± 1 °C and 65 ± 2% RH per ASTM D1776/D1776M. The 14490D construction differs from the other grades (higher tenacity, lower oil pick-up). Tenacity at 0.5% / 1.0% specified elongation and further batch data follow the applicable TDS. Other linear densities on request.
