High-performance polyurethane insulation materials for cold storage are widely used in the international market. In the U.S., the application of polyurethane insulation materials accounts for 57% of the market, surpassing 32% in Japan. In contrast, the share of polyurethane in China's building insulation materials market is less than 10%. In China, the use of polyurethane insulation materials is growing at a rapid pace annually. Due to their irreplaceable stability and energy-saving properties, referring to the situation in developed countries, there is still considerable market potential for polyurethane insulation materials. The promotion of their use in the building energy-saving field will also drive the development of the polyurethane raw materials market.
Currently, the malicious competition in the polyurethane thermal insulation material market is severely squeezing the survival space of compliant enterprises. We will standardize the production order of polyurethane products nationwide, organize industry experts to conduct quality inspections of polyurethane materials, and resolutely expose substandard products, increase penalties, and promote the orderly development of the industry. The "New Emerging Industry Development Outline for the Building Materials Industry of China" proposes that the building materials industry should be guided by the spirit of the 18th National Congress of the Communist Party of China and the Third Plenary Session of the 18th Central Committee, lead and plan the development of new building materials industries with the spirit of reform, follow the overall deployment and requirements of the "Innovation and Enhancement" strategy of the building materials industry, adhere to the decisive role of market resource allocation, stimulate the enthusiasm of market entities, mobilize the strength of the entire industry, and work together with enterprises and associations. A multi-pronged approach is taken to plan, policy, technology, and standards, increasing the research and development efforts of technology, equipment, and products, fully leveraging the role of policies and standards, optimizing the development environment, and creating a favorable atmosphere for the coordinated development of emerging building materials industries, including the building materials industry, to achieve leapfrog and sustainable development. Glass wool thermal insulation material is an important type of wall thermal insulation material.
Glass wool boasts excellent properties such as light weight, low thermal conductivity, good heat resistance, aging resistance, ease of bonding with other substrates, and non-melting droplets upon combustion. It is widely used in Europe and the United States for building insulation in roofs, walls, ceilings, floors, and windows. Currently, approximately 49% of building insulation materials in developed countries like Europe and the United States are made of glass wool, while in China, the application ratio exceeds 75%. The core material does not use Freon as a blowing agent, and it is non-toxic and odorless when extinguished, free of formaldehyde and other harmful substances. The emitted gases are harmless to the human environment, making it recyclable and reusable, aligning with the country's environmental protection requirements and qualifying as a new type of green building material.
