Thermoset reinforcements


Packing function made in dynamic conditions for rotating pumps or turning machines, and in static conditions for valves or taps, is ensured particularly by a compressed braid in a stuffing box. Joint packing is a deformable material which must prevent or control fluid passing between surfaces in relative movement, one towards the other.

Technical aspects

End use

To make these braids, Schappe offers a wide range of dry or coated yarns, depending on the conditions of utilization. Generally, the choice of components will result from the following requirements :

  • Mechanical resistance
  • Temperature resistance
  • Thermal conductivity
  • Lowest friction coefficient
  • Chemical inertia
  • Lowest dilation coefficient

Raw materials used

  • Para-aramid
  • Para-aramid / viscose
  • Preox
  • Carbone
  • Carbone / Inconel


  • High tenacity and specific modulus (light weight)
  • Good bonding with matrix
  • Good fatigue resistance in alternating flexion
  • Good dimensional stability
  • Good resistance to high temperature

Schappe Techniques offers yarns that can lead to extremely light fabrics (down to 40 g/m²) with extremely high mechanical results and dimensional stability.
