When it comes to energy conservation and safety in extreme temperature conditions, OEM alumina fiber thermal insulation blankets have long become the "gold standard" in industries such as metallurgy, petrochemicals, lithium batteries, and photovoltaics. However, what truly extends equipment life by 30% and reduces energy consumption by 15% isn't just any blanket, but Jiuqiang's deeply customized solutions. This 2,000-word article will analyze Jiuqiang's continued leadership in the OEM alumina fiber thermal insulation blanket market, covering materials science, process details, application scenarios, and global OEM partnerships.

1. What is an OEM alumina fiber thermal insulation blanket?
1.1 Definition
OEM alumina fiber thermal insulation blankets are polycrystalline fiber needle-punched blankets with high-purity alumina (Al?O?≥72%) as the primary crystalline phase. They can withstand long-term use at temperatures up to 1,600°C and transient temperatures up to 1,800°C. Its OEM nature means that jiuqiang can be flexibly produced according to customer specifications, including density, thickness, bulk density, packaging, and branding.
1.2 Microstructure
Jiuqiang utilizes a sol-gel spinning process, resulting in fiber diameters of 3–5 µm and a shot content of less than 3%. Its three-dimensional cross-linked structure results in extremely low thermal conductivity (≤0.12 W/m·K at 400°C). 1.3 Performance Advantages
• Ultra-low thermal conductivity: Reduces heat loss by 20% compared to traditional aluminum silicate fiber blankets.
• High resilience: Compression rebound rate ≥90%, eliminating cold bridges after installation.
• Chemically inert: Resistant to acids and alkalis, CO, and H? corrosion, suitable for hydrogen furnaces.
• Environmentally friendly: Compliant with EU REACH and RoHS, and carcinogen-free.
II. Jiuqiang's OEM Customization Process
2.1 Requirements Clarification
Customers simply submit the operating temperature curve, furnace design drawing, target insulation thickness, and installation method. Jiuqiang's Technical Center will complete thermal simulation within 24 hours.
2.2 Formulation Fine-tuning
Using AI algorithms, we adjust the Al?O?/SiO? ratio and add Cr?O? and ZrO? micropowders to achieve thermal shock resistance or enhanced infrared reflectivity. 

2.3 Sample Verification
A4-sized samples will be shipped within 3 days, and customers can conduct on-site open flame testing at 1,200°C.
2.4 Mass Production
Using a 5,000-ton hydraulic needling machine, we can produce continuous, seamless rolls with thicknesses from 6 mm to 50 mm, a width of 1,220 mm, and a single roll length of 7,200 mm.
2.5 Packaging and Traceability
Each roll is individually packaged in heat shrink film, a woven bag, and a pallet. A laser QR code traces the raw material batch, production machine, and quality control personnel.
III. Typical Application Cases
3.1 Lithium Battery Positive and Negative Electrode Roller Kiln
A leading customer in Jiangsu required a kiln temperature differential of ±2°C. Using Jiuqiang's customized 10 mm OEM alumina fiber thermal insulation blanket, the temperature differential was reduced to ±1.2°C, reducing energy consumption by 18% and saving 320,000 Nm³ of natural gas annually.

3.2 Single Crystal Furnace Thermal Field
N-type single crystal furnaces in the photovoltaic industry use Jiuqiang's 24 kg/m³ lightweight blanket, successfully replacing imported Japanese brands, reducing costs by 40% and increasing furnace capacity by 8%.
3.3 Aerospace Engine Ground Testing
A test bench at an aerospace institute needs to heat from room temperature to 1650°C in 30 seconds. Jiuqiang achieved zero thermal surface peeling through 3D stitching of preforms, with a 100% test success rate.
IV. Global OEM Partnership Model
4.1 White Label Manufacturing
Customers focus on the end market, while Jiuqiang provides "invisible" manufacturing and 100% channel protection.
4.2 Co-Branding
Packaging features dual logos, shared technical white papers, and Jiuqiang offers global certification support.
4.3 Technology Licensing
Jiuqiang exports production lines and quality control systems to help customers build local factories, shortening delivery times by 50%. V. FAQ
Q1: How do we ensure long-term use at 1600°C without pulverization?
A: Jiuqiang uses high-purity raw materials and nano-seed control technology to stabilize the fiber grain size below 100 nm, suppressing abnormal grain growth.
Q2: What is the minimum order quantity for OEM?
A: 200 m² for standard specifications, and 100 m² for special specifications.
Q3: Can export packaging be palletized and fumigated?
A: Fumigation pallets and certificates can be provided in accordance with ISPM-15 standards.
