Factory Supply Calcium Silicate Insulation Board with Smooth Surfaces 20mm

Product DescriptionCalcium Silicate BoardCalcium Silicate Board is mainly made from siliceous materials ,lime refractory and reinforcing fiber through the process of slurrying,forming,high pressure steam curing, drying,surfacing ect. When siliceous material and lime refractory is mixed together under high temperature and high-pressure condition, tobermorite,a kind of crystalloid,will come into beting,which has extremely stable performance. So Calcium silicate board whose main component is just this kind of crystalloid, has good fire retardancy, water resistance, high strength,durability and so on.FeatureProduct Characteristics:1)100%non-asbestos 2)Density:1,400-1,600kg/cbm 3)Coefficient of thermal expansion: ≤0.24W/MK(JC/T54) 4)Bending strength: ≥13MPa(GB/T7019-1997) 5)Linear expansionrate: ≤0.1% 6)Water absorption rate: ≤0.19%(GB/T7019-1997) 7)Water penetration rate:0% 8)Water content: ≤10% 9)Incombustibility according to CNS6532 and BS 476 10)2.5-3hours of fire rating for (6mm wall system with W-CSP concrete) 11)Radioactivity:Standard (GB6566-2000)12)Nonflammability: GradeA(GB-8624-1997)Features Heat insulation, stability, damp-proof, soundinsulation, fireresistant and light weight The wall is solid and firm inside, and resistant to impact pressure Painting, tiling and nailing is possible in the news ystem Noise reduction can be up to 46dB Good efficiency Working environment can keep it dry and clean for better managementCertificates with 2.53hours of firerating Specification And Technical DataSpecificationSize2440*1220mm; 2400*1200mmThickness4.5 to 20mmSurface treatmentWith or without sanded surface; bevelledCustom Specifications available on requestedges availableOutstanding characteristicsEnvironmental friendly, 100% non-asbestos, outstanding fire resistance, high tensile and bending strength, remarkable moisture resistance, stable dimension, durable, excellent heat insulation and soundproofing, easy InstallationMain usagePartitioning wall, ceilingOther usageProtecting wall system, movable floor, countertop, panelbillboard, kitchen and bathroom wall,pipeline insulationPhysical propertyRaw materialTobermorite, cement, Quartz sand,  fiberDensity    1.1-1.3 g/cm3Flexural strength>13 Mpa; real test >15 Mpa (GB/T7019-1997)Moisture content
