Continuous Use – High-Performance Polyimide (PI) Insulation Felt
Begoodtex supplies this high-performance Polyimide (PI) needle-punched non-woven felt for aerospace, defense, and high-end industrial sectors. This golden-yellow felt is made from 100% Polyimide (PI) fiber, one of the most superior performance organic fibers available.
Polyimide fiber is engineered for extreme environments. It possesses outstanding thermal stability, allowing for long-term continuous use at 260°C (500°F) and instantaneous exposure to 280°C. As an inherently flame-retardant fiber, it only chars and will not melt, soften, or drip when exposed to open flame.
Core Advantages and Procurement Commitment
- Inherent FR & Thermal Stability: Rated for 260°C continuous operation. Its non-melt and non-drip properties make it ideal for high-end fire barriers and thermal insulation apparel.
- Superior Electrical Insulation: Polyimide is an excellent dielectric material, making it suitable for demanding electrical insulation applications in generators and mechanical/electrical (mechatronics) systems.
- Radiation & Chemical Resistance: Features outstanding resistance to radiation and chemical corrosion, making it a preferred choice for aerospace and defense applications.
- Mechanical Properties: High strength, lightweight, and soft, allowing for easy processing (cutting, sewing) for use in specialty apparel linings.
- Project Supply & Customization: As a professional Technical Textile Factory, we support OEM/ODM customization of various weights (e.g., 100gsm, 300gsm, 550gsm) and thicknesses (0.8mm to 6mm) to provide a stable, reliable supply for your project.
Ideal Applications
Aerospace (Generators, Insulation components), Military & Defense Apparel, Firefighting Garment Liners (Thermal Barrier), NEV Lithium Battery Insulation, Refinery/Steel Mill High-Temp Insulation.

FAQ / Common Questions
- Q1: What is the difference between Polyimide (PI) and Aramid fibers?
A1: Both are high-performance inherent FR fibers. Polyimide (PI) generally offers a higher continuous operating temperature (260°C) and superior electrical insulation and radiation resistance, making it a key material for aerospace applications. - Q2: Will this felt melt or drip when exposed to fire?
A2: Absolutely not. Polyimide fiber is non-combustible. It will only char when exposed to flame and will not melt, soften, or drip. This is its critical feature as a high-end fire barrier. - Q3: Is this suitable for NEV (New Energy Vehicle) battery insulation?
A3: Yes. Its high thermal stability at 260°C, excellent electrical insulation, and non-combustible nature make it an ideal thermal runaway barrier material for lithium-ion battery packs. - Q4: We require 550gsm at 2mm thickness. Can you customize this?
A4: Yes, we are a factory specializing in Project Supply. We can produce this felt in a wide range of weights (100gsm to 800gsm) and thicknesses (0.8mm, 1.5mm, 2mm, etc.) to meet your exact OEM/ODM order requirements. - Q5: What is the lead time for this specialized material?
A5: As Polyimide (PI) is a high-performance specialty fiber, lead times may vary. Please contact our sales team to discuss standard availability (e.g., 300gsm) and lead times for custom-weight Bulk Orders . - Q6: Are you a manufacturer or a trading company?
A6: We are a professional technical textile factory with over 17 years of experience, specializing in OEM/ODM production and international compliance testing for high-performance FR and heat-resistant fabrics.
I. Fabric Packaging
The fabric packaging solution is customizable to meet your specific needs. We consistently use high-quality packaging materials to ensure the protection of the fabric.
The core of our packaging is a sturdy paper tube. It has a thickness of 7mm, an outer diameter of 9cm, and an inner diameter of 7.6cm. This design provides excellent support, preventing the fabric from being crushed or deformed during transit.
For the outer layer, each roll is enclosed in a transparent PE tube bag. This bag has a minimum thickness of 12.5 silk (0.125mm) which makes it highly durable and resistant to tearing. The transparent material allows for easy inspection of the fabric without opening the package, while its properties effectively protect the contents from moisture and dust.
To secure the packaging and for brand identification, the two ends of each roll are sealed with custom-printed adhesive tape. This tape not only firmly seals the PE bag but can also be customized with your brand logo, product information, or other specified designs.
II. Finished Packaging
Our finished products are not only carefully manufactured but also meticulously packaged under strict quality standards. Each item—whether home textiles, bedding, event supplies, medical supplies, clothing, or industrial fabrics—is packed in a way that ensures maximum protection, cleanliness, and presentation value.
We use durable cartons, sealed polybags, and protective inner packaging to safeguard fabrics against moisture, dust, and damage during long-distance transportation. For retail-ready products, we provide customized color boxes, printed labels, and barcode systems, ensuring a professional appearance and easy inventory management.
All cartons are clearly marked with product information and “Made in China” for export compliance. Our packaging team follows international shipping standards, making sure goods are stackable, easy to load/unload, and suitable for sea, air, or land transportation.
This comprehensive approach guarantees that when our products arrive at your destination, they are not only intact and ready for use, but also presented in a way that enhances your brand image and customer experience.
III. Protective Packaging
For high-end fabrics and bulk shipments, we adopt reinforced protective packaging solutions to guarantee the integrity of every roll. Each fabric roll is first individually wrapped in moisture-proof plastic film and securely fastened to prevent dust, humidity, or contamination. After that, the rolls are carefully placed into strong wooden crates for maximum protection during long-distance transportation.
Our wooden crates are manufactured with high-strength materials, reinforced with nails and steel bands, and designed to withstand heavy stacking, impact, and vibrations during shipping. This ensures that even delicate or premium fabrics arrive at their destination in perfect condition without deformation or damage.
In addition, we follow international export packaging standards, making our wooden crates suitable for sea freight, air freight, and land transport. Each crate is clearly labeled with product details and handling instructions, ensuring smooth customs clearance and efficient logistics management.
By adopting this level of protective packaging, we provide our clients with peace of mind, knowing that their valuable goods will be delivered safely, securely, and ready for immediate use upon arrival.
IV. Goods Shipping
When it comes to shipping, we implement strict loading procedures to ensure both safety and efficiency. Goods are carefully arranged and stacked in containers, with optimized space utilization to reduce transportation costs while maintaining stability throughout the journey.
Every carton, roll, or crate is placed in an orderly and secure manner, preventing shifting or collapsing during long-distance transit. When necessary, we apply reinforced strapping, stretch film, pallets, and protective cushioning materials to further stabilize the cargo and protect against vibration, friction, or impact.
Our experienced logistics team follows international shipping standards, coordinating with major freight carriers to guarantee smooth container loading, timely departure, and safe delivery. Containers are also regularly inspected and reinforced to ensure they are clean, dry, and free from potential hazards such as rust or water leakage.
This meticulous process ensures that all products—whether fabrics, textiles, or finished goods—arrive at their destination on time, intact, and in perfect condition, giving our clients confidence in every shipment.
