(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.ApplicationsPUR/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.deep-sea

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./* January 22, 2024 19:08:37
