About Polysulfone (PSU or PSF) material

Polysulfone (PSU or PSF) is an amorphous high performance polymer, the glass transition temperature is 187 °C. It is an amber transparent plastic with excellent properties, including high mechanical strength and rigidity, excellent dimensional stability, outstanding resistance to hydrolysis, good chemical compatibility, excellent radiation stability and good creep strength.

Polysulfone (PSU or PSF) can work well at a wide range tempreture from -100°C (-150°F) to 150°C (300°F), it offers similar mechanical strength with PEI Plastic. Comparing with polyphenylene sulfone (PPSU) and polyethersulfone (PES), PSU offer better transparency. It is also a suitable material to replace polycarbonate plastic or acrylic for applications, for example high temperature hot water, steam, corrosion, etc.

Frequently used profiles are PSU sheet, rod, tube, film, etc. Otherwise, PSU plastic can be injected molding into some complicated parts.

Frequently Asked Questions about Polysulfone (PSU or PSF)

Yes, polysulfones are recyclable! They can break down the imine bond under acidic conditions through a specialized process and then recover when neutralized with a base. Polysulfones can handle heat well, making them perfect for making various eco-friendly products. Some companies offer polysulfone recycling services and ensure the material is reused efficiently.

Yes, you can burn Polysulfone. However, the only important factor about polysulfone is its complex chemical structure, which, over time, makes it hard to ignite the material. You need a substantial amount of heat to burn readily. Even when ignited, it tends to burn slowly and sometimes self-extinguishes when you remove the heat source.

Yes, nitric acid reacts with polysulfone, but it depends on how strong the acid is. It can easily handle weak nitric acid with a density of about 5-40%. But with the high-density acid (71%), it doesn’t resist as well and isn’t safe to use. So, it is better to check the acid strength before using polysulfone with it!

Polysulfone is manufactured through a specialized process named polycondensation. First, two chemicals, including bisphenol A and dichlorodiphenyl sulfone, are mixed. It helps to form polymers. Then, you need to add the water to separate the polysulfone from the mixture. You will have to filter the material and then dry it into a fine white powder. When it is shaped into pellets, granules, or films, the polysulfone is ready to use for different products.

Yes, Polysulfone is food safe! It doesn’t tend to break down with hot water or steam, which makes it perfect for food preparation and sterilization. Even many polysulfone types are food-safe, which is often found in kitchens and medical tools that need cleaning.

The main difference between polysulfone and polyethersulfone is their chemical structures. PES is more complex in structure. It can handle very high temperatures that are up to 400°C. Polysulfone has a simpler structure with isopropylidene groups, which can handle the heat. PES works well in tough chemical applications, whereas polysulfone is great for see-through products.

Polysulfone is a high-grade thermoplastic that equips excellent mechanical, chemical, and thermal properties. It is an amorphous polymer that doesn’t have defined melting points. Other than that, it has excellent dimensional stability and is highly resistant to chemicals and hydrolysis.

PSU is an acronym for transparent, high-performance thermoplastic. It is tough and shows stability against heat and chemicals. Due to superior chemical and physical properties, it is safely used in medical instrument components, manifolds, medical trays, autoclavable instruments, and trays. Also, you will find it in electrical equipment and vehicle construction.

PSU is a high-performance thermoplastic that can effectively work against high temperatures. The temperature range of the PSU is from –100°C to 150°C, which makes it perfect to use where a high heat range is required. They are amorphous polymers and have no specified melting point.

The key difference between PTFE and polysulfone is their unique characteristics. PTFE is a slippery material that is perfect for use in non-stick cookware and water filtration applications. On the other hand, Polysulfone is strong, durable, and handles high heat. You can use it for making food equipment or medical tools.

PES stands for ‘polyethersulfone,’ whereas PEI stands for ‘Polyetherimide.’ Both are high-grade thermoplastics with almost similar properties. However, in most PEI applications, PES can be an excellent alternative that ensures food resistance to creep, transparency, and self-extinguishing.

A well-known brand name for polysulfone is ‘Udel.’ It is a high-performance transparent plastic that ensures higher heat resistance and good hydrolytic stability. Also, it can be molded into a variety of different shapes.

There are three most common types of polysulfone: polysulfone (PSU), polyethersulfone (PES), and polyphenylene sulfone (PPSU). PSU is the most transparent and least expensive, and it is often used in medical devices and filters. Besides, PES has good chemical and hydrolysis stability, which is ideal for certain applications. PPSU is the most expensive and durable plastic.

Normally, a high-quality epoxy adhesive is used to glue polysulfone. It ensures excellent bonding between the pieces used without any degradation while using. The adhesive ensures good heat resistance in applications. Make sure to clean the polysulfone surfaces and clean any contaminants before you apply the adhesive.

Polysulfone is used in various applications, for example healthcare, laboratory equipment, aerospace, and automotive. You will also find it in food handling equipment, coil bobbins, and chemical processing equipment. Due to high transparency, heat resistance, and low flammability, it ensures durable functionality in all applications.

Another name of PSF is PSU, full name Polysulfone. It is similar to PES, but different.

PES have advantages of PSU, and it has better comprehensive performance than PSU. Particularly, it has higher heat resistance than PSU. PES can be processed by general thermoplastic processing methods. Thus, it is known as the first engineering plastic that combines high heat distortion temperature, high impact strength and the top molding processability.
