ebaboard:board materials for foundry patternsThe ebaboard product series comprises board materials available in various thicknesses. ebaboard products havemany advantages: dimensional accuracy and stability, durability, and highly stable edges. You benefit through superbmachinability and very little dust build-up.MaterialColourApplicationsMaterial propertiesDensity at 20°C (g/cm 3 )Delivery dimensions (mm)Physical DataFlexural strength (MPa)Flexural modulus (MPa)Compressive strength (MPa)Impact resistance (Charpy)(kJ/m 2 )Heat resistanceHDT DIN EN ISO 75 B (°C)Shore hardness (Shore D)Coefficient of thermalexpansion (10 -6 K -1 )Abrasion (Taber) (mg)Type/Application wt./Rotationsebaboard 60red brownMaster models,negatives, core centresdense surface,very easily worked0.65 ± 0.021500 x 500 x 251500 x 500 x 501500 x 500 x 751500 x 500 x 1001500 x 500 x 20017 ± 3-17 ± 35 ± 170 ± 362 ± 3approx. 50--ebaboard Sred brownMaster models, foundrypatterns, core centresdense surface,fine structure,very easily worked0.70 ± 0.021500 x 500 x 251500 x 500 x 501500 x 500 x 751500 x 500 x 1001500 x 500 x 1501500 x 500 x 20025 ± 3-24 ± 36 ± 167 ± 265 ± 3approx. 55--ebaboard M 04yellowFoundry patterns, coreboxes, pattern platesvery abrasion resistant,highly impact resistant,dense surface,good edge strength1.20 ± 0.021000 x 500 x 501000 x 500 x 751000 x 500 x 100120 ± 52950 ± 30090 ± 566 ± 987 ± 384 ± 3approx. 77approx. 105H 18/500/500ebaboard PW 920greenFoundry patterns, coreboxes, pattern plates,negativesvery easily worked,good edge strength,dense surface,impact resistant,no generation of dust1.21 ± 0.051000 x 500 x 301000 x 500 x 501000 x 500 x 751000 x 500 x 10072 ± 51807 ± 15056 ± 525 ± 390 ± 379 ± 2approx. 109approx. 101H 18/500/250ebaboard 140blueFoundry patterns, coreboxes, pattern plateslow thermal expansion,highly abrasionresistant,fine structure,easily worked,very good edge strength1.38 ± 0.031000 x 500 x 501000 x 500 x 751000 x 500 x 100109 ± 54175 ± 100102 ± 519.5 ± 287 ± 285 ± 3approx. 65approx. 62H 18/500/50016Pattern made of ebaboard M 04 Pattern made of ebaboard PW 920
