High Density Polyurethane Foam prefabricated house
sandwich Panels
Polyurethane (PUR) and polyisocyanurate (PIR/PIR+) foams are expanded plastics produced as a result of a polyaddition reaction with isocyanates in the presence of activating and stabilizing agents. As the blowing agent we use a traditional hydrocarbon - pentane, which is perfectly safe for the ozone layer. By using special polyester-derived polyols in polyisocyanurate (PIR/PIR+) foams, we obtain more aromatic bonds. Additionally, by means of increasing the so-called index in appropriate conditions, polyisocyanurate rings of high chemical resistance are produced. As a result, in comparison to flat rings in the PUR foam, in the PIR/PIR+ foam three-dimensional structures are obtained.
The effect is that the PIR/PIR+ foam behaves much better in fire than the PUR foam. It also exhibits better mechanical and insulating properties. PUR/PIR/PIR+ foams are characterised by very good physical and chemical parameters, high resistance to moisture, high chemical resistance and resistance to fungi and mildew. Compression strength with 10% deformation is 150 kPa, with density of 40 kg/m3± 3.
We offer a range of Headstream PIR-cored fire resistant insulated panels for all types of temperature controlled applications & controlled environment projects.
The high thermal performance of the PIR (PolyIsoCyanurate) core offers higher energy savings and/or reduced thicknesses of construction when compared to other insulated panel systems. They are fire resistant, hygienic and fibre free.
Applications
PUR/PIR/PIR+ sandwich panels are manufactured in a process of continuous foam pouring between the steel sheet lining. They are designed for use as wall and roof components of industrial, storage and public utility buildings. They are also used as insulation in the food and refrigeration industries as components for cold rooms and freezers. They may also be used in agriculture as components of farm facilities. Another example of application is thermal insulation in building engineering. Thanks to the variety of profile types of panel plates lining and a wide selection of paint coats in various colours, our products can give a unique character to any building. Additionally, panels with the PIR/PIR+ foam core may be successfully used in buildings with higher requirements for fire resistance.

Headstream is the factory of Shandong Hark Steel Material Co.,ltd. And Headstream brand started in the 1990s, the company was officially established in 2003, has developed into one of the most influential brands in China's construction materials industry,is China's largest sales of PIR/PU energy saving sandwich panel supplier, mainly engaged in construction steel manufacturing and coating steel plate trade business, is aprofessional metal cladding and steel structure product services and manufacturers.
Through nearly 30 years of development, an industrial layout with mainly steel structure building and metal cladding products was formed, including metal exterior wall, metal roof, clean room cladding material, cold storage cladding and steel structure engineering.It has 7 major intelligent manufacturing bases in Shandong, Chongqing, Jilin, Hubei, Guangdong, Guangxi and Ningxia,with an annual output of high-end polyurethane energy-saving board of 25000000 meters.
Due to the strategic development requirements, the original Hongyuan Steel Products Business Department was overall upgraded to Shandong Jinnuo New Material Co., Ltd., the original Hongyuan coated steel trade was renamed Shandong Jinpeng Exhibition Wing Coated Steel Co., Ltd., and the original Hongyuan Purification Panel Business Division was upgraded to Shandong Jingcheng Purification Technology Co., Ltd.
The new name is more professional service, Headstream brand will always put customers in the first place, wholeheartedly serve every product customer.
