Due to the superior flow behavior, high CTI, strong mechanical performance at high temperatures and weld-line strength, Stanyl is often used in connectors, for example USB-C connectors. Since Stanyl is the only semi-crystalline aliphatic polyamide operating in the high-temperature field, the comparison with other materials is generally with other material classes, like PPS or semi-aromatic polyamides, referred to as PPA.
For clarification, we displayed a PA66 based material to show the differences with other aliphatic polyamides, showing that Stanyl is uniquely situated in this class of materials. In the graph to the left, the loss modulus of three different materials are displayed—a PA66 blue , two different PPAs green and purple , a PPS red , and Stanyl orange as determined in a dynamic mechanical thermal analysis in tensile mode. The DMTA can be divided into the glass plateau region, below the glass transition temperature, and in the rubber plateau region at temperatures higher than the glass transition temperature.
Where in the glass plateau all polymers have a similar modulus being Here, irrespective of the polymer class displayed in the graph, the modulus of Stanyl is highest of all polymers. A similar effect can also be seen for the short-term mechanics testing—in this case tensile performance. The PPA2 deviates as this material is below its glass transition temperature. In this case the wear was determined in a gear application where the wear depth as function of the number of cycles was being studied.
The wear was determined to be much higher for PA66 materials than for the Stanyl material. The main elements that are providing this strength is the creep and fatigue performance of Stanyl versus PA66 based materials.
In both properties Stanyl outperforms the other aliphatic polyamides as the stiffness and strength level in Stanyl is higher due to the higher degree of crystallinity. Although the chemical structure of Stanyl brings the fast crystallization speed and the high degree of crystallinity, it also brings a higher degree of water absorption than other aliphatic polyamides. Naturally this absorption of water negatively impacts the dimensional stability of Stanyl materials and especially for unfilled materials as it contains the highest amount of polymer.
Consequently, for the highly filled materials that have a high glass fiber or carbon fiber loading, the water absorption is much lower and the impact on the dimensional stability less severe. The second effect that moisture has on any polyamide is the lowering of the glass transition temperature Tg.
In this area, the mechanical performance of Stanyl is higher than PA By using different types of additives, the good electrical properties and the high mechanical performance can be combined in thermal conductive materials. TWF10 has an excellent track-record in gear applications and structural parts. Diablo HDT is specifically designed for high-demanding automotive under-the-hood applications.
Direct and easy access to our broad portfolio of high-performance plastics: request a quote or order a sample. You can also simply ask us a technical question. The first commercializations 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 are the basis of the three key strengths of Stanyl being excellent high-temperature mechanics, excellent wear and friction performance and superior flow.
These strengths are what drives the business of Stanyl. Because of these features, this materials displays exceptional retention of mechanical properties after passing through the glass transition, giving rise to its high-temperature performance. Sintered metal gears are being replaced with high-performance plastic gears in automobiles because the demand to lightweight vehicles and increase fuel efficiency is far from just a trend—it is driven by meeting new and upcoming legislation to reduce emissions.
As consumer acceptance of electric vehicles continues to rise, the need for equivalently advanced material solutions in growing. DSM offers a wide range of product portfolio which addresses these diverse needs.
Looking for the perfect Synology NAS? Check out our NAS selector! Businesses with 50 or fewer employees need to store ever-increasing amount of data. They also require affordable solutions to back up data, share files, and collaborate on a single file at the same time.
However, very few have the luxury of dedicated IT support. Many begin by storing files on a traditional server, but when backup, or collaboration issues arise, the server is quickly rendered inadequate.
Others choose public cloud storage, which is convenient for collaboration but raises concerns about control of the data and costly subscription fees. NAS can simplify your work and solve the above issues. Traditional file-sharing practices are fraught with inefficiency.
Some businesses use email attachments to share files and eventually face file size limit and version control issues. Synology NAS, as an on-premises centralized storage device, can fulfill the needs of modern file sharing and collaboration.
Drive supports the SMB local access as well as the web portal and mobile app for remote access. By simply selecting a DSM account, you can share files internally with notifications.
Synology NAS also made collaborating with colleagues and sharing projects with customers efficient. Office enables your team to work simultaneously and interact by leaving comments. Chat allows your team to have quick discussions and never miss notifications. MailPlus allows for a private mail server and a web-based mail client to boost productivity. Backing up data scattered across PCs, servers, and VMs is always challenging - remote offices and employees can make things even more complicated.
Active Backup for Business makes backup easy through a unified, intuitive console without license fees. For PC backup, it supports bare-metal recovery to restore the OS, settings, applications, and data; your employees can have instant, self-service recovery without bothering IT admins. Learn more about Active Backup for Business.
For small businesses relying heavily on Microsoft and Google Workspace, purchasing space for data archiving or auditing is expensive. We also suggest opting for a backup protection. If the active NAS malfunctions, the passive unit will take over in seconds, meaning your employees can continue to access files and services. Compared to traditional solutions, you can set up and maintain Synology HA without extensive technical knowledge.
Where traditional solutions require expensive hardware, Synology HA is affordable even on a budget-friendly 2-bay NAS. Tutorial on Synology HA. With Surveillance Station, you'll get a wide array of security options to secure your investment and livelihood.
