PU rigid foam has excellent thermal insulation property and its heat conductivity is better than other insulation materials. It is mainly used in 3 areas including construction, refrigerator and other home appliances with insulation requirement like pipeline, storage tank and reactors.
Construction conservation has received increasing attention and construction department also announced standard of construction conservation. Construction exterior wall need to be covered with insulation materials and PU rigid foam will play an important role while 2011 could be challenging year. On March 14th, the ministry of public security put forward the No.65 document and improved the standard of fireproofing grade of construction material. Simple PU rigid foam failed to reach the Standard A for fire proof and inorganic material or the composite materials replace it, which reduce the usage amount of PU rigid foam. When it came to the spring festival, PU rigid foam usage in construction ended.
Summer could be busy season for refrigerator consumption and spring and summer are production busy season. When it come to the autumn and winter, there is a tradition to put in new home appliance and purchasing passion increased. When it come to the late period of December, operation rate of refrigerator decreased to low level.
Equipment insulation began during the construction and maintenance period. There is shutdown of facility heard from plants in north
Spring festival period could be low point for PU rigid foam and industry slowed. Producers and salesmen all tried to clear the inventories and waited for new spring.
