All known polyurethane polyurethane , is the main chain containing carbamate groups repeated macromolecular compounds collectively.It is composed of an organic diisocyanate or polyisocyanate compound with two or more hydroxyl addition polymerization .
Polyurethane foams are widely used at present .
Polyurethane elastomers in a wide range of hardness with high elasticity and strength, excellent abrasion resistance, oil resistance, fatigue resistance and vibration resistance, has a " wear-resistant rubber ," said.Polyurethane elastomer production of polyurethane products is small, but the polyurethane elastomer with excellent performance , has been widely used in metallurgy , petroleum, automotive, mineral processing, water conservancy, textile, printing, medical , sports, food processing, construction and other industrial sectors.
PU is a polyurethane , PU leather polyurethane composition of the epidermis is now widely used such materials garment factories producing clothing , commonly known as leather garments . PU is the English abbreviation for polyurethane , polyurethane chemistry Chinese name is also its quality is good or bad , good bag and moreimported PU leather ;
Polyurethane composite board
Polyurethane PU sandwich composite panels also known .
Polyurethane composite board core material from the middle of the upper and lower color plates plus polyurethane foam composition , using the world's advanced six -component mixing pouring techniques online automatic operation can be completed online once the plant community center or proportioning the ingredients mixing process ,online can be adjusted according to the temperature , thereby producing a distinctive high-intensity, energy-saving , green building panels .
Due to its fire proof performance, but also other materials commonly used in the core composite panels Edge , Edge polyurethane composite board made of high quality color coated steel sheet as surface materials , continuous rock wool, glass cotton as core material , high-density rigidtongue and groove filled with polyurethane foam , high pressure foaming after curing , automatic compacting Bumian controlled by long double coated with composite molding , hanging with the traditional cotton maintenance materials, fire protection , thermal insulation effect is better , longer-lasting performance, easy to install, elegant appearance .Is a steel building maintenance materials leader.
Generally used for roofing buildings outer plate which has good insulation , heat insulation, sound insulation and polyurethane no combustion, compliance with fire safety .Polyurethane upper and lower plates plus joint action , with high strength and stiffness, lower plate smooth, clear lines , increase the indoor appearance , flatness .Easy installation, short construction period, appearance, is a new type of building material .
The sandwich panels are lightweight , beautiful and good corrosion resistance , can be directly processed , it gives the construction industry , shipbuilding , vehicle manufacturing industry , the furniture industry , the electrical industry to provide a new type of raw material , played by steelwood, efficient construction , energy conservation , pollution prevention and other good results .
Edit this paragraph Applications
Polyurethane composite panels as building energy-saving insulation materials, in Europe, America, Japan and other developed countries has been widely used, a penetration rate of 80% , used in China is less than 10%.Polyurethane sandwich panels as an excellent energy-saving insulation materials, its excellent thermal insulation , fire protection, thermal insulation properties and can solve China's energy consumption crisis to provide efficient solutions.
Polyurethane sandwich panels are widely used in large industrial plants , cold storage , garage, mobile homes , exhibition hall, exhibition hall , stadium, shopping centers, airports , power plants , villas , hospitals, and high-rise office buildings and other areas of formation , as excellent thermal insulationperformance is mainly used in industrial and civil construction of the roof and walls .
Edit this paragraph insulation properties
A grade polyurethane composite panels have excellent insulation properties
5cm thick composite board insulation equivalent to 1m thick concrete results, with excellent insulation properties .
Polyurethane foam is a new type of polymer materials with bulk density, low thermal conductivity, high obturator excellent performance and corrosion resistance

Roof edge
Polyurethane roof with dark nail connection , the board lap closer.
Unique waterproof tank designed to effectively prevent rainwater infiltration and avoid cold bridges phenomenon .
40mm crest height , greatly improving roof bearing capacity .At the same time ensuring the building insulation effect , reduce customer costs of construction, roof slope down to 3%.
Wall panels advantage
Dark nail connection , the surface without exposed screws , building wall gracefully.
High flexural capacity , wall superior mechanical properties , reducing the dependence on auxiliary steel structure .
Insulation performance , reduce the cost of construction of indoor air conditioning unit .
A variety of appearance , walls and beautiful.Baidu Bai [ 1 ] technical superiority
Efficient insulation
Class A is an organic composite board insulation materials the lowest thermal conductivity (≤ 0.022), 5cm thick polyurethane composite panels A-level equivalent to 1m thick concrete insulation effect .A grade polyurethane composite board is to achieve our goal of building energy efficiency 75% ideal insulation products
Super Flame
A grade composite board 30 minutes at 1000 °C flame burning not wear .
Lasting durability
A grade composite board after six months or more weather resistance test , the performance is stable, with life and architecture .
Good dimensional stability
A grade polyurethane composite panels compressive strength 200kp above , the plate temperature change resistance, no deformation.
Low carbon environmental
A grade polyurethane composite plate using bio-based raw materials , freon-free foam, do not use countries prohibit or restrict the use of harmful substances , green.
