BRONZE FILLED POLITEF® Bronz filled POLİTEF has high rigidity, resistance, resistance to corrosion, thermal property and resistance to fatigue. Its specific gravity is higher than the other alloys. Due to its above mentioned properties, it is used at segments, valve sets and bearings.   BRONZE FILLED POLITEF® PRODUCTS · FULL and EMPTY RODS · FULL and EMPTY WEDGES · PLATES · SKIVED 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 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 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
