High-Temperature Mechanical Performance

Stanyl® is a high-performance aliphatic polyamide with a melting temperature of 563° F (295° C). Due to its high crystallinity and fast crystallization speeds, it offers three key strengths:

  • Excellent high-temperature mechanical performance
  • Excellent wear and friction properties
  • Superior flow

 

Why Stanyl®

Why Stanyl®

Stanyl® is the first high-temperature polyamide and the only aliphatic polyamide in its class. Thirty years ago, it defined this class of materials and today it is still the most widely used polymer basis. The symmetry of the 46 structure ensures that the polymers fit in the crystal in multiple ways, thereby giving rise to high crystallization speeds and high crystallinity. This combination makes the material ideal for high-temperature applications due to excellent mechanics as well as wear and friction behavior, where the flow and the flow-mechanics balance are one of a kind.

The latest addition to Envalior's (formerly DSM Engineering Materials) Stanyl® portfolio is B-MB, a bio-based mass balancing solution. B-MB is a 100% bio-based high-temperature polyamide that empowers customer sustainability by generating a 50% lower carbon footprint while delivering the same high performance and quality as conventional Stanyl®.

 

Characteristics and Properties

The first commercialization's of Stanyl® were achieved 30 years ago. Currently, it is the largest single polymer being used in the high-performance polyamide landscape. The symmetry of the chemical structure lays the foundation of its success as it provides the basis for the high degree of crystallinity and fast crystallization speed. These two features allow for the following characteristics and properties:

  • High-temperature mechanical performance
  • Low coefficient of friction and higher wear resistance
  • High degree of water absorption
  • Thermal conductivity
