Fully Resin Impregnated Graphite Plates

Fuel Cell Grade Graphite Plates can be machined on both sides to be used as bi-polar plates. These plates exhibit high electrical and thermal conductivity, incredible resistance to chemicals, and are densified and resin-filled for low permeability. Thickness Tolerance: +/- 0.003 in Length and Width Tolerance: +/- 0.1 in Technical Specifications: Bulk density: 1.95 g/cm3 Particle size: 13 - 15 microns Shore hardness: 85 HSD Breaking strength: 60 MPa Compressive strength: 200 MPa Max temperature it can handle in oxidative environments: 200 deg C Electric Resistivity: 11 - 13 micro.Ohm.meter Coefficient of Expansion: 4.8 x 10^-6 per deg C
