Advanced Polyimide Solutions for Demanding Applications

PI Virgin Powder

Our premium-grade PI Virgin Powder represents the purest form of polyimide, engineered to withstand the most challenging operational conditions. This high-purity material maintains structural integrity at continuous temperatures up to 260°C (500°F), outperforming conventional polymers in extreme thermal environments.

Key advantages include:

• Exceptional chemical resistance against acids, bases, and organic solvents
• Outstanding mechanical strength with low coefficient of friction (0.1-0.3)
• Superior electrical insulation properties (dielectric strength >200 kV/mm)
• Minimal outgassing characteristics for vacuum applications

Primary applications span aerospace components (bearing cages, thrust washers), precision industrial molds, and high-temperature electrical insulators where material purity and thermal stability are critical.

PI + Graphite Raw Material

The PI+Graphite composite synergizes polyimide's inherent thermal stability with graphite's tribological and conductive properties. This advanced material system delivers:

• Enhanced wear resistance (50% lower wear rate than virgin PI)
• Improved thermal conductivity (5-10 W/m·K) for heat dissipation
• Tunable electrical conductivity (10^-3-10² S/cm)
• Maintained thermal stability up to 300°C in inert atmospheres

This material excels in automotive powertrain components (bushings, seals), high-load bearing applications, and electronics thermal management solutions where combined thermal, mechanical, and conductive properties are required.

PI ESD Resin

Our PI ESD Resin formulation addresses critical electrostatic discharge challenges in sensitive electronic environments while preserving polyimide's core benefits. The material features:

• Controlled surface resistivity (10⁶-10⁹ Ω/□)
• Static decay time <2 seconds (per ANSI/ESD STM11.11)
• Maintained mechanical strength (tensile strength >100 MPa)
• UL94 V-0 flammability rating

Essential for semiconductor wafer handling equipment, aerospace avionics enclosures, and medical electronics where both ESD protection and material performance are non-negotiable requirements.
