LED Packaging

High-Reflectivity Polymers for Surface-Mount LED Packaging

Specially formulated grades of high-reflectivity white Amodel® polypthalamide (PPA) deliver long-life performance in high-brightness LEDs.

Proprietary formulations add unsurpassed stability to a polymer matrix proven to offer the highest thermal performance. Ideal for today’s more intense application requirements. Enhanced processability allows molders to meet extreme productivity demands in complex, multi-cavity molds.

Key features

  • High initial brightness
  • Luminosity retention
  • Withstands SMT up to 310°C
  • High flow for low profile LEDs
  • Excellent adhesion to epoxy and silicone encapsulants

Mobile Electronics

Electronic Components

Amodel® PPA outperforms standard polyamides in high-temperature electronic applications such as micro-speakers, micro-receivers, micro-switches, connectors, camera modules and LEDs. Outstanding electrical properties and high heat resistance make Amodel® PPA suitable for electronic component exposed to SMT processing.

Key features

  • High heat resistance
  • High strength and stiffness
  • Retains properties in humid environments
  • Excellent chemical resistance
  • Good surface appearance

Oil & Gas

With a heat deflection temperature of 536°F (280°C) and continuous use temperature of 338°F (170°C), Amodel® resin can deliver the thermal performance you need for the short term as well as the long haul. It retains its exceptional mechanical properties – strength, stiffness, fatigue and creep resistance – over a broad temperature range and in high humidity environments.

Typical applications

  • Compressor rings
  • Poppets
  • Back-up seal rings
  • Electrical connectors
  • Labyrinth seals
  • Motor end plate
  • Bearings
  • Bushings
  • Sucker rod guides


Amodel® PPA Outperforms Conventional Polyamides

Amodel A-1133 DW and A-1145 DW drinking water grades are approved for contact with potable water and are suitable for applications requiring intermittent exposure to hot chlorinated water.

  • Better resistance to hot chlorinated water
  • Superior resistance to creep and fatigue
  • Lower moisture absorption
  • Improved dimensional stability

Amodel® PPA Outperforms Standard Nylon

After being exposed to 90°C water with 5 ppm chlorine for 1500 hours, Amodel PPA retains nearly 60% of its load carrying ability while PA 6,6 has no load carrying ability due to severe loss of weight and structural integrity
