STP Vacuum Insulation Panel: The "Nanoscale Invisible Guardian" of the Global Building Energy Efficiency Revolution

### I. Core Performance: Redefining the Benchmark of Thermal Insulation Materials

1. Nano - level Vacuum Insulation Technology

  - Ultra - low Thermal Conductivity of 0.002W/(m・K): By evacuating to below 0.02Pa to block air convection and combining with silica aerogel core material, a "solid - state vacuum" insulation layer is formed. For example, a 1cm - thick STP board is equivalent to the thermal insulation effect of 5cm of traditional materials, which can reduce building energy consumption by 40% - 60%.

  - Wide - temperature - range Adaptability: It can maintain stable performance in extreme environments from - 200℃ (LNG storage tanks) to 600℃ (industrial high - temperature pipelines), with heat loss reduced by more than 60%.

2. Safety and Long - term Protection

  - Class A Non - combustible Certification: It releases no toxic gases during combustion, passes the UL - 1709 fire - resistance test, and is suitable for high - risk scenarios such as petrochemical and power industries.

  - Six - layer Composite Gas - barrier Film Technology: The water - repellency rate is ≥99%. In high - humidity coastal areas and cold northern regions, its service life is up to 60 years, with a performance degradation of <5%.

3. Lightweight and Space Optimization

  - Thickness of only 3 - 15mm: It is 70% thinner than traditional materials, releasing 5% - 10% of the building's usable area. It is especially suitable for high - density urban buildings and old - building renovation projects.

  - Compressive Strength ≥0.2MPa: It has passed the 12 - level typhoon and 8 - degree earthquake resistance tests, ensuring reliable structural safety.

4. Green and Environment - friendly, and Circular Economy

  - The core material uses 70% industrial waste microsilica powder, with no Freon emissions during production. It has obtained the three - star certification of China Green Building Materials, contributing to LEED and China's three - star green building ratings.

### II. Diverse Scenarios: All - round Applications from Construction to Industry

1. Construction Energy - saving Field

  - Passive Houses and Ultra - low - energy Buildings: After using STP boards in the project at 23 Heizstrasse, Germany, the energy consumption is only 1/10 of the average in Munich, and the wall thickness is reduced to 20cm (traditionally 30 - 40cm).

  - Prefabricated Buildings: Cooperated with Tongji University to develop the reverse - casting technology, eliminating the outer leaf board, reducing the wall thickness by 40%, shortening the construction period by 30%, and reducing the cost by 150 yuan/㎡.

  - Old - building Renovation: In the renovation project of the Beijing New Children's Palace, the energy efficiency can be increased by 60% without expansion, and 50㎡ of usable area is released.

2. Cold - chain Logistics Field

  - Vaccine and Pharmaceutical Transportation: The nano - vacuum insulation board of Anhui Zhongke Baoruite is used by the EU for vaccine cold - chain. In a 35℃ environment, it can maintain a constant temperature of - 18℃ for 70 hours, reducing the cold - chain loss rate from 8% to 1.2%.

  - Refrigerated Trucks and Cold Storage: The Kevothermal vacuum insulation board of Sealed Air extends the heat - preservation time of refrigerated trucks to 120 hours, reduces the weight by 30%, and increases the cruising range by 10%.

3. Industrial and New Energy Field

  - High - temperature Equipment Insulation: After using STP boards in the blast furnace pipelines of steel plants, the surface temperature drops from 80℃ to 45℃, with heat loss reduced by 50%.

  - Thermal Management of Power Batteries: The 4680 battery pack of CATL uses STP boards, with the temperature difference between battery cells ≤5℃, increasing the charge - discharge efficiency by 15% and reducing the risk of thermal runaway.

### III. Technical Advantages and International Certifications

1. Patent and Standard Leadership

  - A total of 325 patents (11 international patents), participated in the formulation of ISO 16478 international standards and more than 20 national/industry standards. The technology covers the entire chain of core materials, processes, and construction.

  - Passed international certifications such as BS ISO 16478:2023 and ASTM C177, and complies with EU ETAG 004 and US ICC - ES standards.

2. Intelligent Production and Customization

  - The fully - automated production line has an accuracy of 0.01Pa. Each board undergoes 1000 bends + helium - mass - spectrometry leak detection, with a 100% factory - passing rate.

  - It provides a full - chain service from laboratory samples to ten - thousand - ton - level mass production, and can customize density (10 - 50kg/m³), color, and special functions (such as antibacterial and conductive).

### IV. Global Market Trends and Policy Drivers

1. International Policy Promotion

  - The new EU energy - efficiency regulation (ERP) requires a 40% increase in the energy efficiency of refrigerators, promoting the penetration rate of STP in the white - goods field from 1.6% to 15% in 2025.

  - China's "Limited Value of Power Consumption and Energy Efficiency Grades for Household Refrigerators" revision plan is expected to be released by the end of 2025, which is expected to drive a 25% annual growth in the demand for STP.

2. Market Prospect

  - From 2025 to 2030, the market size of vacuum insulation boards in China is expected to exceed 20 billion yuan, with an annual growth rate of 15%. The construction energy - saving sector accounts for more than 60%, and the cold - chain logistics sector has a growth rate of 25%.
