Sheet polyamide Meldin®

rodtubeball bearing

Overview
Meldin® polyimide materials provide high dimensional stability at elevated temperatures and a controlled balance of wear resistance and friction. These PI-based formulations are used where long-term performance under thermal, mechanical and chemical stress is required, including aerospace, semiconductor and industrial systems.

Formats & Forms

• Stock shapes: sheets, rods, tubes
• Finished machined components: bearings, bushings, wear parts, guide rings, vane elements, thrust washers
• Custom-designed geometries and near-net shapes

Applications

• Aviation and aerospace components
• Space systems and satellite mechanisms
• Semiconductor process and handling equipment
• Industrial components (pump & valve parts, piston rings, wear strips)

Material Series (examples)

• Meldin® 2000 PI Based — legacy range: good tensile and compressive strength with stable dimensional behavior.
• Meldin® 6000 PI Based — self-lubricating grades for extended service under high temperature and load; improved chemical and radiation resistance.
• Meldin® 7000 PI Based — thermosetting polyimide series with extremely low dimensional change on thermal cycling.
• Meldin® 8000/9000 PI Based — porous, lubricant-filled formulations for bearing cages and low friction applications.
• Specific formulations such as Meldin® 7001 and 7021 are available for tailored high-performance requirements.

Key Features & Benefits

• High continuous operating temperature capability (materials rated for extended use at elevated temperatures)
• Exceptional dimensional stability under thermal cycling
• Wear resistance and controlled friction for long service life at higher loads and speeds
• Total process control from powder to finished component
• Direct forming and precision machining available for selected grades
• R&D-driven formulation support and collaborative engineering for customization

Resources

• Manufacturer datasheets and handbook available as downloadable PDFs for material selection and properties.
• Technical videos and supporting documentation describe Meldin® origins and processing guidance.

Technical specifications

• Continuous operation capability to high temperatures (materials stated capable of operations up to ~600°F / ~315°C depending on grade).
• Meldin® 7000 series: demonstrated dimensional variation under thermal cycling of less than 0.04% when cycled from ~73°F (22.8°C) to 500°F (260°C) over a two-day period.
• Available in multiple PI-based formulations (2000, 6000, 7000, 8000/9000) optimized for tensile strength, self-lubrication, wear resistance, low friction, and chemical/radiation resistance.
• Offered as stock shapes (sheets, rods, tubes) and as precision-machined parts (bearings, rings, vanes, thrust washers, custom geometries).
