High Performance PI Staple Fiber 2D*51MM
Product Overview

Our 2D*51MM polyimide staple fiber is a premium industrial special fiber manufactured through advanced dry spinning and high-temperature thermal imidization processes. As one of the organic polymer fibers with the best comprehensive performance available, it integrates ultra-high temperature resistance, inherent flame retardancy, high strength, chemical corrosion resistance, radiation resistance, and excellent electrical insulation properties.

Unlike ordinary post-finished flame retardant fibers and medium-temperature resistant fibers, the exceptional performance of polyimide fiber stems from its unique aromatic imide ring molecular structure, which is an inherent material attribute. With a limiting oxygen index of 38% or higher, it will not melt, drip, or burn when exposed to fire, instead forming a dense carbonized layer that blocks heat and flames, with ultra-low smoke and non-toxic combustion characteristics.

Core Advantages
Ultra-High Temperature Stability

Maintains stable mechanical and physical properties at 260°C for long-term continuous use, with thermal decomposition temperature exceeding 570°C.

Inherent Permanent Flame Retardancy

LOI ≥38% with zero melt drip. Self-extinguishes immediately after leaving fire source with ultra-low smoke density.

High Strength & Dimensional Stability

Breaking tenacity above 4.0 cN/dtex with dry heat shrinkage less than 0.3% at 280°C.

Broad-Spectrum Chemical & Radiation Resistance

Excellent resistance to organic solvents, acids, oils, and gamma/UV radiation for harsh industrial environments.

Excellent Processability

2D denier with 51mm standard length compatible with mainstream spinning and nonwoven equipment.

Frequently Asked Questions
What is the long-term service temperature of this polyimide fiber?
Can work stably at 260°C for long periods, retains over 85% strength after 100h aging at 280°C, with thermal decomposition temperature exceeding 570°C.
Is the flame retardant effect permanent? Will it produce molten drip when burning?
Inherent molecular flame retardant (not surface coating) with permanent stable performance. Only carbonizes when burning - no melting, no dripping, no shrinkage.
How does it compare with aramid and PPS fiber in high temperature filtration?
Higher temperature resistance, better chemical resistance and longer service life than PPS and meta-aramid, suitable for harsher conditions with lower total cost of use.
Is 51mm length compatible with needle punching and ring spinning machines?
Yes, 51mm is the standard length for industrial nonwoven and spinning processing, fully compatible with mainstream equipment.
