PPSU sheet and rod are amorphous, high-performance thermoplastic engineering plastic profiles. Below is a detailed introduction to their characteristics:

Characteristics:
Physical Properties:
Light specific gravity, generally around 1.32 g/cm3, which makes PPSU products lighter and easier to install and operate.
Good toughness, capable of absorbing energy and maintaining integrity under external impact, making it less prone to cracking or damage. For example, in applications requiring impact resistance, such as sports equipment or children's toys, PPSU products demonstrate excellent impact resistance.
High impact strength, able to withstand significant impact forces without noticeable deformation or damage, ensuring safety in high-demand applications.
High heat resistance coefficient, with a long-term working temperature of up to 180°C and short-term tolerance for even higher temperatures. It maintains good physical properties and dimensional stability in high-temperature environments, making it suitable for manufacturing components under high-temperature conditions.
High mechanical strength, including high tensile strength, enabling it to withstand significant tensile and compressive forces without breaking or deforming. It is suitable for manufacturing structural components that bear certain loads.
High thermal expansion coefficient, with minimal dimensional changes during long-term operation at 180°C, which is crucial for applications requiring high dimensional precision, such as precision instruments and optical equipment components.
High surface hardness (Shore 80D), offering good wear and scratch resistance, making it less prone to scratching or wear and ensuring a longer-lasting appearance and service life.
High dimensional stability, with minimal dimensional changes under varying temperature and humidity conditions, ensuring product precision and reliability.
Strong creep resistance, with very little deformation under long-term stress, making it suitable for manufacturing components that bear long-term loads.
Low water absorption rate, typically less than 0.2%, ensuring that PPSU maintains good performance in humid or water-exposed environments without performance degradation or dimensional changes due to water absorption.

Chemical Properties:
Good hydrolysis resistance, even under prolonged use in high-temperature and high-humidity environments, making it less prone to hydrolysis and ensuring material stability. It is suitable for manufacturing products in prolonged contact with water or humid environments, such as bathroom fixtures and water treatment equipment components.
Excellent resistance to acid and alkali corrosion, with good tolerance to common acids, alkalis, and salt solutions. It is widely used in chemical and environmental protection fields for manufacturing chemical pipelines, valves, containers, and other equipment.
High chemical stability, with good resistance to most organic solvents and oils, making it suitable for applications involving chemical exposure, such as laboratory equipment and pharmaceutical devices.
High flame retardancy (UL-94V0 rating), self-extinguishing, with low smoke and toxicity during combustion, meeting fire safety requirements. It is suitable for applications requiring high flame retardancy, such as electronic and electrical equipment and building materials.
Good machinability, easily processed into various shapes and sizes with minimal issues like chipping or burrs, reducing processing costs and improving production efficiency.
Physiologically inert (suitable for food contact), non-toxic and harmless to humans, making it suitable for manufacturing food processing equipment, tableware, baby bottles, and other products in direct contact with food.
High electrical insulation coefficient, excellent dielectric properties, and high insulation breakdown strength, making it an excellent insulating material in the electronics and electrical fields for manufacturing wire and cable insulation layers and electronic component encapsulation materials.

Application Areas:
Biotechnology: Due to its good biocompatibility, chemical corrosion resistance, and high-temperature stability, it is commonly used for equipment components in biotechnology, such as cell culture dishes, bioreactors, and fermentation tanks.
Medical Field: Used for manufacturing medical device components, such as surgical instruments, endoscope parts, and dental tools. Its ability to withstand repeated high-temperature steam sterilization makes it suitable for high-temperature and steam-resistant components, such as sterilization trays and surgical instrument cases. Additionally, its good radiation resistance makes it suitable for manufacturing radiation-resistant components, such as parts for radiotherapy equipment.
Industrial Field: In semiconductor manufacturing, it is used for semiconductor device components, such as wafer carriers and chip fixtures. Due to its excellent insulation and high-temperature resistance, it is commonly used in communication equipment, precision instruments, and optical manufacturing for components like fiber optic connectors, optical lens mounts, and precision instrument housings. In electrical engineering, it is used for manufacturing electrical insulation components, sockets, and switches. In the automotive industry, it is used for manufacturing components around automotive engines, interior parts, and fuel system components.
