Expanded vermiculite and vermiculite products are the lastest light-weight thermal insulation material as their heat-conducting coefficient are low and light weight. The specific properties of vermiculite in preserving heat and cold, thermal insulation, sound absorption, shock, fire, bacteria, chemical and cold resistance are remarkable. It is also non-flammable, low in moisture absorption, high in absorption, and possesses a certain amount of mechanical strength.Vermiculite is one kind of Natural mineral, non combustible, smokeless, avinrulent, flavourless under 1200℃ high temperature.So, it is regarded as the best fireproofing and heat insulation material int the world.Therefore, it is particular suitable for use in metallurgical, electrical, petrochemical, and construction industries. It is an indispensable thermal insulation material for all kinds of high-temperature boilers, gas and liquid pipes, and for heat and cold preset-vation is different types of refrigeration and heating installations.The product is used in a large number of projects. Such as Kai Tak Airport and MTR of HongKong, airport of Malaysia, some important common projects in BeiJing, TianJin and ShangHai.
