BRONZE FILLED POLITEF® Bronze Filled POLİTEF has high rigidity, resistance, resistance to corrosion, thermal property, wear resistance and tiring resistance. Its specific gravity is higher than the other alloyed materials. It is used used at bearing strips, valve sets, segments due to its above mentioned properties.  BRONZE FILLED POLITEF® PRODUCTS · FULL and EMPTY RODS · FULL and EMPTY WEDGES · PLATES · FILMS · FELTS · SEGMENTS · BEARING STRIPS  BRONZE 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 UPON BREAKING OFF ASTM D- 1708  %  250-300 290-300  155-165  170-180 STROKE DRESISTANCE 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 UNDER 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   0,035 0,048  0,085  0,083 THERMAL EXPANSION ASTM E 831 10-5/0°C  12-14 Eki.14  8-11  8-9 IGNITION TEMPERATURE ASTM D- 1929  °C  530 630  630  640 ** Too high to be measured
