Chengdu Artech Specialty Graphite Co.,Ltd is one of the leading China graphite heat shield manufacturers and also a professional graphite heat shield supplier,Website: , welcome to import products from our factory.Product name: Graphite heat sheild                         Graphite heat sheild for hihg temperature and vaccum furnace             Material: high pure graphiteSize: customizeApplication: high temperature and vaccum furnaceDensity: 1.65-1.88 g/cm3Compressive strength: 30-240MpaFlexural strength:7-85MpaSpecific electrical resistance:6.5-15μΩmBrand Name: OEMMOQ: 1 pcsDelivery date: 20 daysPackage: Polywood or custom package          Function:1.Graphite heat sheild have high thermal stability.Graphite does not melt but sublimes at about 3627 ℃ .2.Graphite heat sheild have good electric conductivity.As temperature rises, electrical conductivity increases. 3.Graphite heat sheild have high thermal conductivity.The thermal conductivity of graphite is higher than that of many metals and falls with increasing of temperature. 4.Graphite heat sheild can resist thermal shock. so rapid heating or cooling is not a problem.5.Graphite heat sheild can resist corrosion.It can be widely used in acid based environments.6.Graphite heat sheild are not wetted by molten glass or by most molten metals.7.The tensile,compressive and flexural strength of graphite heat sheild are very high.8.Graphite heat sheild have high purity. Graphite can be purified to 20-30 ppm in block or less than 5 ppm for thefinished items.
