Polyimide – Super Engineering Plastic

Polyimide is designated a super engineering plastic because its performance characteristics exceed what is achievable with conventional high-performance thermoplastics. Its operational temperature range of -269°C to +400°C covers conditions from deep cryogenic environments to extreme high-temperature industrial processes, a range no other plastic in this portfolio approaches.

Where PEEK operates up to 250°C and PEI up to 170°C, Polyimide continues to perform reliably at temperatures well above both. This performance comes from the polyimide polymer backbone itself, which has one of the highest thermal stabilities of any organic material.

Polyimide sheets are supplied in a precision format of 360x320mm, reflecting the specialized and high-value nature of the material. Round bars are available from 2mm diameter, suitable for miniature precision components in electronics and instrumentation.

Exceptional Thermal Stability

Operational temperature range of -269°C to +400°C. The widest thermal range of any material in the Plastix Factory portfolio.

Outstanding Wear Resistance

Resistant to wear under sustained friction contact, particularly in filled grades engineered for tribological applications

Stable Friction Level

Consistent and predictable friction behaviour across operating conditions, critical for precision mechanical components

Perfect Electrical Insulation

Excellent dielectric properties maintained across the full temperature range, suitable for high-specification electrical insulating applications

Flame Retardant

Inherently flame retardant without additives, suitable for aerospace and electronics environments with strict fire safety requirements

Good Processability

Machinable by CNC turning, milling and drilling to precise tolerances for small, high-value components

Available Product Forms

Polyimide is available in precision sheet format and round bars across all five variants. Log in to check live stock availability, pricing and lead times for your specific dimensions and variant requirements.

Sheets

Precision format 360x320mm in thicknesses from 1 to 50mm across nine standard thicknesses. All dimensions in standard stock. Suited for precision machined flat components, insulating plates and wear elements.

Round Bars

Solid bars from 2 to 85mm diameter in 1000mm lengths. Wide diameter range covers miniature components in electronics and instrumentation through to larger industrial parts. Full range in standard stock.

Cut-to-Size

Custom cut to your exact dimensions from standard sheet or bar stock across all five variants.

Finished Parts

CNC-machined precision parts to your technical drawings. Suitable for bearing bushings, thrust washers, seals, insulating rings and precision structural components in aerospace and semiconductor applications.

Typical Applications

Polyimide is used in environments where no other plastic in the engineering or high-performance range can deliver the required combination of thermal stability, wear resistance and electrical performance.

Electronics and Electrical Engineering

Used for insulating components, carrier plates, precision housings and structural parts in electronics manufacturing and electrical engineering where stable dielectric performance at extreme temperatures is required. The ESD grade provides controlled surface resistivity for semiconductor and LCD applications.

Aerospace and Aviation

Applied in aerospace structural and functional components where lightweight, high-temperature performance, flame retardancy and dimensional stability under combined thermal and mechanical stress are simultaneously required. Polyimide covers the cryogenic to high-temperature range that aerospace applications demand.

Semiconductor Manufacturing

Used in semiconductor fabrication equipment, wafer handling, test sockets and precision components in chip manufacturing environments where chemical resistance, dimensional precision, thermal stability and electrostatic control are all critical.

Automotive

Applied in high-temperature under-bonnet components, transmission parts and engine-adjacent elements where sustained elevated operating temperatures and wear resistance exceed the capability of standard engineering plastics.

Medical Devices

Used for precision medical device components, instrument parts and structural elements where biocompatibility, sterilization resistance and dimensional precision are required in miniature high-performance applications.

Machinery and Heavy Industry

Applied in precision bearing elements, thrust washers, wear rings and sliding components in heavy machinery where dry-running capability, high load and extreme temperatures are combined. Graphite and MoS grades are specified for these applications.

Available in 5 Variants

Each variant is engineered for a specific set of tribological, electrical or environmental requirements. Select the grade that matches your application conditions.

Polyimide N – Natural

Highest purity Polyimide with excellent electrical insulation and outstanding chemical resistance.

Polyimide G15

15% graphite-filled grade with self-lubricating properties.
