Stanyl® is a high-performance aliphatic polyamide with a melting temperature of 295°C. Due to its high crystallinity and fast crystallization speeds, it offers three key strengths:
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®.
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:
Stanyl® PA46 is the first high-temperature polyamide and the only aliphatic polyamide in its class, making it an ideal choice for crankshaft balance gears. The polymers fit in the crystal in multiple ways, giving rise to high crystallization speeds and high crystallinity. This combination makes it ideal for high-temperature applications since it comes with a melting temperature of 295°C. Typical applications include:
Stanyl® PA46 is a reliable solution for spatulas and other kitchenware. Stanyl® PA46 offers a much higher melting temperature and heat deflection temperature (HDT) than PA66, ensuring durability and performance under high-heat conditions. Both Stanyl® PA46 and PA66 have significantly higher melting temperature resistance compared to PP and PA6, making them suitable for demanding kitchen environments. Moreover, Stanyl® TE200F6-FC is food-approved, ensuring safety in applications involving direct contact with food. Common applications include:
High-performance aliphatic polyamide is formulated to reduce fire risk. Stanyl® is rigorously tested for optimal processing, creep resistance, durability, blister resistance and applicable UL safety standards. Stanyl’s® design stiffness and high flow properties lower the total cost to manufacturers by ensuring high yields while demonstrating superior cracking performance. Its high comparative tracking index performance reduces the risk of tracking by 50%. Common applications include:
