5 Advantages of PAI Compression Molded Advanced Polymer

Polyamide-imide (PAI), as manufactured by Symmtek Polymers is a High-Performance Engineering Thermoplastic Molded Through Compression Molding.

Polyamide-imide (PAI) is a specialized engineering polymer that offers exceptional strength and stability in extreme high-temperature environments. At lower temperatures, PAI still offers outstanding durability, impact resistance and chemical resistance, making it one of the more versatile high-performance polymer options for a range of demanding applications.

High-Temperature Stability Combined with High-Strength Durability

PAI is often used in high-temperature applications in which competing thermoplastics would degrade and lose their mechanical properties. The Amide linkage imparts flexibility, while the Imide linkage imparts high Tg, and high service temperature.

Compression molded and reinforced for enhanced mechanical properties, Symmtek’s complete line of PAI material products can reliably offer service temperatures up to 500F. This makes it one of the preferred engineering thermoplastics for the semiconductor, and chemical processing equipment manufacturing sectors.

  • Reliable high-temperature stability to 500°F (260°C). PAI’s glass transition temperature (Tg) of 537°F (280°C), is higher than its maximum operating service temperature establishing excellent heat resistance and dimensional stability.

  • Superior strength and stiffness compared to most other molded plastics.

  • Outstanding wear resistance in high load, and high speed conditions, impact resistance and chemical resistance to most organic chemicals. Excellent performance in the presence of industrial gases, hydrocarbons, automotive and aircraft fuels and fluids and lubricants, makes it an ideal candidate for automotive and aircraft component applications.

  • Suitable for a wide range of industrial and manufacturing applications that demand harsh thermal, chemical and high-wear conditions.

The Performance Benefits of PAI – A Premium Engineering Plastic

  • Excellent strength, stiffness and stability across a wide range of temperatures.

  • Engineered to provide maximum performance and reliability for high-temperature applications.

  • Exceptional impact resistance and wear performance

  • High tensile strength and elasticity combined with high compressive strength.

  • Outstanding low thermal expansion coefficient combined with high heat deflection temperature make PAI suitable for a wide range of industrial manufacturing applications and products requiring high temperature performance up to 500°F (260°C).
