CARBON FILLED POLITEF® The most significant property of CARBON FILLED POLITEF is its high resistance to corrosion under load and its deformity resistance. It is a material with high thermal conductivity. It is ideal to be used at wet environments. It is used at environments where  high resistance, high rigidity and lightness are required. Nowadays, it is used generally at plane and space industry, transport sector(coachwork, leaf arc, shaft, bridge liable to be corroded), machine industry, medicine and sport equipments sector.  CARBON FILLED POLITEF® PRODUCTS · FULL and EMPTY RODS · FULL and EMPTY WEDGES · PLATES · BEARING STRIPS · SKIVED FILMS · GASKETS · PACKING BOXES · SEGMENTS · FELTS  CARBON FILLED POLITEF® COMPARATIVE TECHNICAL VALUES TABLE PROPERTY TEST METHOD UNIT PURE POLITEF 15% GLASS-FIBRE POLITEF 25% CARBON POLITEF 60% BRONZE POLITEF SPECIFIC GRAVITY ASTM D 1457/18  gr/cm³ 2,14-2,2  2,1-2,28 2,04-2,16  3,8-4,0  USAGE TEMPERATURE - °C -260/+260  - - - MELTING TEMPERATURE ISO 3146 °C 325-330  - - - BREAKING TEMPERATURE - °C -200  - - - PULLING RESISTANCE ASTM D- 1708 kg/cm²  250-300 220-240  165-170 170-175 ELONGATION AT BREAKING ASTM D- 1708  %  250-300 290-300  155-165  170-180 STROKE RESISTANCE ASTM D- 256  cm.kg/cm  15,5 14  8,5  11,0 SHORE D HARD ASTM D- 2240  -  53-57 57-62  60-67  63-70 DEFORMITY UPON LOAD 230°C, 1day, 140kg/cm² ASTM D- 621  %  9,5-11 9,8  5-6  5-5,5       DIELECTRIC RESISTANCE ASTM D- 149  KV/mm  50-80 16-19  13-19  ** THERMAL CONDUCTIVITY ASTM C- 177 Kcal/cm.°C.hour   0,035 0,048  0,085  0,083 THERMAL ELONGATION ASTM E 831 10-5/°C  12-14 10-14  8-11  8-9 IGNITION TEMPERATURE ASTM D- 1929  °C  530 630  630  640 ** Too high to be measured
