with Strong Mechanical Properties

From the automotive and the E&E industries to mechanical engineering and consumer goods, Ultramid® Advanced polymers are engineered for high-performance applications. the new Ultramid® Advanced Polyphthalamide (PPA) portfolio by BASF consists of five polymers with about 50 compounds. Widely used as a choice for metal replacement, Ultramid® Advanced polymers are ideal for lightweighting, allowing greater design options at a lower cost compared to parts made from metal.


Why Ultramid® Advanced?

Why Ultramid® Advanced?

Ultramid® Advanced molding compounds are available unreinforced or reinforced with minerals, short or long glass fibers, or carbon fiber for special applications. These polyphthalamides are known for their high mechanical strength, stiffness and thermal stability. In addition, Ultramid® Advanced offers good firmness at low temperatures, exhibits favorable sliding friction behavior, and is highly processable These PPA polymers are made to withstand high temperatures while maintaining their strength, including lead-free soldering processes across a variety of industries.

Characteristics and Properties

Ultramid® Advanced PPA materials can be used for many applications because of their customizability and high-performance mechanical and thermal properties. Applications include automotive and mobility, electrical and electronics, construction, furniture, sanitary ware and more. In addition, Ultramid® Advanced can be processed by a variety of methods including extrusion and injection molding.

Available Options

The Ultramid® Advanced portfolio includes grades with the following options:

  • Optimized for injection molding or extrusion for easy and stable processing
  • Available with or without flame-retardants
  • Equipped with a variety of heat stabilizers
  • Available in a range of colors from uncolored to laser-markable black
  • Unreinforced or reinforced with minerals, short glass, long glass, or carbon fiber

Chemical and Mechanical Properties

Characteristics and properties found across all Ultramid® product lines include:

  • Partially aromatic chemical structure: All types offer good to excellent mechanics at elevated temperatures.
  • Hydrophobic properties: These polymers can withstand humidity and contact with challenging media while maintaining
  • Low water uptake: Plastic parts exhibit high dimensional stability in humid environments.
  • Compatibility with lead-free soldering processes: These compounds resist damage and maintain strength when exposed to the high temperatures required for lead-free soldering. This makes Ultramid® Advanced products extremely well-suited for electrical and electronics (E&E) applications.
