For cutting-edge applications such as lithium battery separators, automotive gaskets, and home appliance insulation, the fiber paper produced by ceramic fiber paper factories must be both as thin as a cicada's wing and fire-resistant and shock-resistant. Jiuqiang boasts Asia's first 2,400 mm wide fiber paper production line with fully closed-loop dust removal, offering OEM customization for a full range of sizes from 0.5 mm to 5 mm. This article takes you inside Jiuqiang's cleanroom and explains the cutting-edge technology behind the ceramic fiber paper factory.

1. Definition and Classification of Fiber Paper
1.1 Composition
Jiuqiang uses high-purity aluminum silicate fiber, a small amount of organic binder, and an inorganic binder, resulting in an organic content of less than 1% after firing.
1.2 Specifications
• Thickness: 0.5–5 mm
• Density: 180–220 kg/m³
• Tensile Strength: ≥0.8 MPa (2 mm)
II. Jiuqiang Dust-Free Production Line
2.1 Wet-laid Fourdrinier Forming
Pulp uniformity CV <3%, thickness tolerance ±0.05 mm.
2.2 Vacuum Drying at Low Temperature
Prevents fiber shrinkage and ensures flatness.
2.3 Laser Online Thickness Measurement
3,000 data points collected per 1 m², enabling real-time closed-loop adjustment.
III. OEM Customization Capabilities
3.1 Composite Lamination
Can apply aluminum foil on one side and PSA adhesive on the other, forming the product in one step.
3.2 Die-cutting and Punching
CCD vision positioning, accuracy ±0.1 mm, daily production capacity of 1 million small gaskets. 3.3 Food-Grade Coating

Certified to FDA 21 CFR 177.1550, suitable for oven door seals.

IV. Success Stories

4.1 Tesla Induction Heating Pad

Produced by Jiuqiang 0.8 mm ceramic fiber paper factory, with a breakdown voltage of 10 kV and a 60% weight reduction.

4.2 German Coffee Machine Insulation Sheet

1 mm thickness, 24-hour continuous operation at 220°C, no odor.

4.3 5G Base Station Power Supply

Using Jiuqiang 2 mm paper as the insulation layer, the temperature rise is reduced by 20°C.

V. Cooperation Process

Consultation → Drawings in 2 hours → Samples shipped in 72 hours → Small batches in 7 days → Monthly settlement in 30 days.

When you're looking for a reliable ceramic fiber paper factory, Jiuqiang's 0.5 mm thickness and 1200°C temperature offer endless possibilities for innovation.
