China polyurethane rigid foam Market Research and investment forecast report (2022 Edition)

Content abstract ：

Polyurethane foam is mainly made of isocyanate and polyurethane rigid foam , In foaming agent 、 catalyst 、 Under the action of flame retardants and other additives , Mixing by special equipment , High molecular polymer formed by high-pressure spraying and foaming on site . There are two kinds of polyurethane foam, soft foam and hard foam . The soft bubble is an open cell structure , The hard bubble is a closed cell structure ; Soft blisters are divided into skinned and non skinned .

Polyurethane rigid foam means that no obvious deformation occurs under a certain load , Foam plastic that cannot return to its original state after deformation due to excessive load , It has excellent physical and mechanical properties 、 Acoustic performance 、 Electrical properties and chemical resistance , In particular, the thermal conductivity is extremely low , yes - A kind of excellent thermal insulation material and structural material . Polyurethane rigid foam is mainly used in refrigeration and heat preservation and building energy saving industries .

Polyurethane rigid foam is not a standardized product , Rigid foam combination polyurethane rigid foam industry barriers are high . Different initiators 、 Different PO The number of connections can get different grades of monomer polyurethane rigid foam , Its hydroxyl value 、 viscosity 、 appearance 、 The water content and application fields are different . Composite polyurethane rigid foam is typical “ Formula type ” product , There is room to adjust the amount and proportion of each raw material in the formula . Because isocyanates are homogeneous , The final performance of polyurethane is basically determined by the combined polyurethane rigid foam .

2021 In, China's household appliance refrigeration industry consumed rigid foam polyether 56 More than ten thousand tons , It is the main application field of hard foam composite polyether , It is also the most high-end application market . And in developed countries , The main consumption field of hard foam composite polyether is the field of building external insulation ; In China, , The refrigerator （ ark ） Refrigerated container refrigeration industry has always been the largest consumption field of hard foam polyether , Accounted for nearly 50%.

2017 Consumption of polyurethane rigid foam in China 176.0 Ten thousand tons of , Year-on-year growth 8.6%;2018 Consumption of polyurethane rigid foam in China 180.0 Ten thousand tons of , Year-on-year growth 2.3%;2019 Consumption of polyurethane rigid foam in China 183.0 Ten thousand tons of , Year-on-year growth 1.7%;2020 Consumption of polyurethane rigid foam in China 206.0 Ten thousand tons of , Year-on-year growth 12.6%;2021 Consumption of polyurethane rigid foam in China 247.0 Ten thousand tons of , Year-on-year growth 19.9%. Including 10000 tons of hard foam composite polyether 、 polymerization MDI133.7 Ten thousand tons of .
