Joint packing is a deformable material which must prevent or control fluid passing between surfaces in relative movement, one towards the other. TECHNICAL APSECTS 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 Properties 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.
