Item : ?NS302 -Blue DurostoneProduct DescriptionDurostone NS302-Blue , all of our item are made by the high temperature nanometer fiber felt and high performance epoxy resin, than with anti-static high mechanical strength are glass fiber made of composite materials. To made the different is the formulation of recipe and the temperature control during the production. This item can withstand the temperature more than 300 degree (10~20seconds). And keep its mechanical strength, smoothness and original color when continuously used during the temperature of 280℃Product Features-Excellent chemical, resistance , High protection on chemical attack erosion -Excellent dimensional stability at high operation temperature including the lead-free process-Low thermal conductivity-Excellent Machining properties enabling the manufacture of complex design solder pallets and fixtures-Conform to RoHs and Environmental Health Safety requirementHow to choose the durostone material There are different grades durostone material for choosing, ?it depend on your production requirement and your products ,the high grade material can be reuse more than 20000 times some are less , and the pricing are different too .please kindly check the & quot;Technical Data& quot; for choose reference or contact us for advice.?Technical DataTest Item ?????NS-301NS-302NS-302NS-302NS-302NS-306NS-503ColourBlackGreyDark redBlueGreenBlackBlackDensity( g/cm3 )1.81.851.851.851.851.902.00Flexural Strength @ 23 ℃（MPa)360360360360360360360Flexural Strength @ 150 ℃（MPa)180180180180180200260Flexural Strength @ 180 ℃（MPa)110120? ?120120120? ?130150Modulus of Elasticity @23 ℃（MPa)18000180001800018000180001800018000Modulus of Elasticity @150（MPa)800090009000900090001200014000Modulus of Elasticity @180 ℃（MPa)-----1000010000Water Absorption(%)??<0.20<0.20<0.20<0.20<0.20<0.20<0.20Coefficient of Linear Expansion(10-6/K) between 30 ℃and 200?℃13121212121111Thermal Conductivity(W/moK)0.570.570.570.57　　0.570.570.53Maximum Operating Temperature
