Polysulfone (PSU) granules, identified by CAS number 25135-51-7, represent a class of high-performance engineering thermoplastics that offer a unique combination of properties. NINGBO INNO PHARMCHEM CO.,LTD. provides insight into these materials, enabling clients to make informed decisions for their specific project requirements. Understanding the detailed properties and optimal processing methods is key to harnessing the full potential of PSU.

The physical form of PSU as granules simplifies handling and processing. These granules are typically light yellow and amorphous, with excellent mechanical properties including high tensile strength, rigidity, and wear resistance, even at elevated temperatures. The material's low melt viscosity requires careful control during processing, with pre-drying to a moisture content below 0.05% being essential before molding operations such as injection molding, extrusion, or thermoforming. Post-processing heat treatment is often recommended to alleviate internal stresses and ensure dimensional stability.

PSU's thermal performance is a significant advantage. It can withstand a continuous use temperature of 160°C and a short-term temperature of up to 190°C, with a high heat distortion temperature. This makes it suitable for applications where heat resistance is a primary concern, such as in automotive components and some appliance parts. The inherent flame resistance and self-extinguishing nature further enhance its safety profile in various applications. When you purchase PSU, you are investing in a material that performs reliably under thermal stress.

The chemical stability of PSU is another cornerstone of its utility. It resists a broad spectrum of chemicals, including most acids, alkalis, and salts. While it may swell in certain ketones and esters, its overall resistance profile is superior to many other thermoplastics. This chemical inertness is particularly beneficial in the production of filtration membranes, where resistance to process chemicals and the ability to maintain structural integrity are paramount. The application of PSU in industrial water treatment and wastewater clarification highlights its efficacy in harsh chemical environments.

When considering the purchase of PSU, it's important to note its properties like high mechanical strength and resistance to fatigue. However, its resistance to UV and weathering can be poor, necessitating protective measures if exposed to prolonged outdoor conditions. NINGBO INNO PHARMCHEM CO.,LTD. can assist in selecting the most appropriate grade and formulation of PSU to meet the specific environmental and performance demands of your project, ensuring you get the best value when you buy PSU.

In conclusion, PSU granules offer a compelling package of properties for demanding applications. By understanding their thermal stability, chemical resistance, and processing requirements, manufacturers can effectively leverage this advanced material.
