Fire Intumescent Strip With High Expansion RatioFeaturesIntumescent strip as gaskets at the flange joints of different pipings, valves, pumps heat-exchangers, condensers, pressurized vessels, towers, manholes, hand holes and to make gaskets for liquid level gages and crystallizers.Fire intumescent strip, mainly used in steel door, wooden doors and door frames. Between door leaf. When fire intumescent strip will be Automatic inflation.Sealing the door gap, blocking air circulation between two Spaces. Effectively prevent fire early smoke, toxic gas and heat and control the harm of human body fire spread. 1.Expansion temperature: starting temperature 199 ℃, the body expansion temperature 347 ℃; 2.Linear expansion ratio: the swelling of greater than or equal to the original thickness of 3 to 10 times; 3.High temperature and combustion performance: temperature to 980 ℃ and keep 90min, not burning, not grey; 4.Smoke performance: the fire test for 90 min, door seal installation of left, right, And no obvious leakage cracks in upper smoke, smoke prevention performance is more than 90 min. 5.Environmental capacity: under room temperature and 90 humidity conditions placed expansion ratio unchanged.Company introductionQingdao Tennry Carbon Co., Ltd? is the professional manufacturer for graphite products in Shandong province.
