Product Description
SPC-1006 polyol is a fully formulated polyol blend, especially developed for PU rigid foam insulation, applied with metal face sheet or non-metalic face sheet like Mgo, OSB, etc.
It contains sufficient quantity of blowing agent HCFC 141B to achieve the foreseen foam density. When SPC-1006 polyol and isocyanate (MDI) are mixed together using suitable equipment, the good flowability of the resulting foam makes it possible to achieve a homogenous foam density throughout the cross section of the panel. Foams which are allowed to cure for a sufficient time in the mould according to the foam thickness show good adhesion to the surface and good dimensional stability.
SPC-1006 polyol contains sufficient amount of fire retardant for the foreseen applications and the foams obtained by using it together with isocyanate (MDI) are classified as B2 or B3 according to DIN 4201 classification. It is recommended that a mould surface temperature of 40℃ is maintained during production.

Application
1. Refrigeration and refrigeration equipment for household appliances and food industries
PU rigid foam is the most ideal thermal insulation material for freezing and refrigerating equipment, which can achieve better insulation efficiency.
Refrigerators and freezers are commonly used in households and food industries. The refrigerator and the refrigerator with PU hard foam as the heat insulation layer have a thin heat insulating layer, and under the condition of equal external dimensions, the effective volume is much larger than that of other materials as the heat insulating layer, and the weight of the electric appliance is reduced.
The PU hard foam has high strength and is poured between the shell of the refrigerator and the inner liner to form an integral body. There is no “heat bridge”, which ensures the excellent heat insulation effect of the refrigerator and the freezer. Hard polyurethane foam plastic insulation materials are generally used in household electric water heaters, solar water heaters, and beer barrel sandwiches. PU rigid foam is also used in the manufacture of portable incubators for the transport of biological products, pharmaceuticals and foods that require heat preservation.
With the development of fisheries and meat processing industry, these foods are often processed, frozen and refrigerated on site to reduce spoilage and improve resource utilization. The refrigeration and refrigeration rooms and large-scale cold storages of enterprises such as marine fisheries and meat food processing industries also use polyurethane foam as insulation materials, and are often assembled with hard foam metal sandwich panels, which is convenient and quick.

2. industrial equipment and pipe insulation
Many brewing, chemical, storage and transportation enterprises have different requirements for heat preservation and cold preservation. PU hard foam construction is convenient, sanitary and excellent in thermal insulation effect, and it is a good thermal insulation material.
Storage tanks and pipelines are commonly used in industrial production and are widely used in petroleum, natural gas, oil refining, chemical, light industry and other industries. In order to prevent heat or cold from being lost during storage or during transportation, cold/heat storage tanks and pipes must be insulated.
The shape of the tank is spherical and cylindrical, and the PU rigid foam can be constructed by spraying, pouring and pasting the pre-formed foam. It is more suitable for the spraying method of large storage tanks; it is also possible to first add a thin metal sleeve to the storage tank and then mold it by pouring. The regular shape of the cylindrical storage tank can be a process of bonding the pre-formed hard foam block to the outer wall of the can.
Storage tanks for storage of low-temperature media generally require a moisture-proof layer in the rigid foam. For the storage of liquefied petroleum gas and liquefied natural gas cryogenic storage tanks (temperature below -30 ° C), PU rigid foam is placed inside or outside the metal tank, preferably using glass fiber reinforced rigid foam.
As a pipe insulation material, PU rigid foam is widely used in the insulation of pipelines in crude oil pipelines and petrochemical industries. It has successfully replaced water-absorbing materials such as perlite.
The hot water pipelines for central heating projects in cities and factories generally use PU rigid foam as insulation material, which requires long-term resistance to 100 °C. The main pipeline requires 130 °C or higher temperature. Some high-temperature PU rigid foam products have been Developed for such use. Central heating pipes are required to be buried underground as much as possible, and require a certain pressure resistance performance and a long service life.

3. building materials
Building construction is one of the most important areas of application for PU rigid foam. In the United States and other countries, the construction of PU hard foam accounts for about half of the total consumption of hard foam, which is more than double the amount of hard foam used in refrigerators and freezers. Many countries in the world have clear regulations on the energy consumption of building construction, which promotes the application of rigid foam in building construction. The annual consumption of polyurethane foam in construction in the United States is about 300,000 tons, accounting for 65% of the building foam market (the rest is polystyrene and phenolic foam), accounting for about 50% of the total PU foam.
In China, hard foam has been widely applied to the insulation and waterproofing of residential and office building roofs, thermal insulation of walls, cold storage, grain storage and other insulation materials. Spray hard foam for the roof, plus a protective layer, which has the dual effect of heat insulation and waterproof.
The metal surface rigid polyurethane sandwich panel is made of flame-retardant rigid polyurethane foam (two different formulations of PU and PIR), and the color coated steel sheet is used as the surface material, and continuously formed by PU or PIR foaming. And, also known as composite sheet. It combines light weight, high strength, heat insulation, waterproof and decoration. It is a multi-functional new building material that is easy to produce, construct and install.
At present, domestic metal surface rigid polyurethane sandwich panels are widely used in industrial plants, warehouses, stadiums, residential buildings, villas, movable board houses and combined cold storages, etc., for roofing and wall panels. Because of its light weight, heat insulation, waterproof, decorative and other characteristics, and convenient transportation (installation), the construction progress is fast, which is very popular among designers, construction and developers.
The PU hard foam is filled in the hollow brick, and can be made into a hard foam filled hollow brick, which has better heat preservation effect. It can also be made into PU rigid foam concrete. The density of this concrete block is about 200kg/m3, the compressive strength is 0.59~0.78MPa, and the thermal conductivity is about 64mW/(m·K), which can be made into large-sized building components.
PU rigid foam sheets can be made into a variety of folding mobile houses, which are used as temporary temporary rooms. For example, if the surface of a 10mm thick PU rigid foam is covered with polyethylene, it can be made into a folding house, or a PU hard foam can be used to make a full PU hard foam spherical temporary house.
Water conservancy facilities such as concrete dams need to adopt thermal insulation measures during cold winter construction, and PU hard foam can be sprayed on the new concrete surface as insulation layer. In the severe cold area, polyurethane insulation board can be used as the anti-freezing material for channel lining, which reduces the damage of the channel rigid lining material by frost heave and ensures the stability of the lining and the safe use of the channel.
