White PPSU sheet vacuum forming processing

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 lightweight during use, facilitating installation and operation.
Good toughness, capable of absorbing energy and maintaining integrity under external impact, making them less prone to cracking or damage. For instance, in applications requiring impact resistance, such as sports equipment or children's toys, PPSU materials exhibit excellent impact resistance.
High impact strength, enabling them 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. They maintain good physical properties and dimensional stability in high-temperature environments, making them suitable for manufacturing components under high-temperature conditions.
High mechanical strength, including high tensile strength, allowing them to endure substantial tension and pressure without breaking or deforming. This makes them ideal for structural parts that bear certain loads.
High thermal expansion coefficient, with minimal dimensional changes during long-term operation at 180°C. This 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 them less prone to scratches or abrasion and ensuring a long-lasting appearance and service life.
High dimensional stability, with minimal size changes under varying temperature and humidity conditions, ensuring product accuracy and reliability.
Strong creep resistance, with very little deformation under long-term stress, making them suitable for components that bear sustained loads.
Low water absorption rate, typically less than 0.2%, allowing PPSU to maintain good performance in humid or water-exposed environments without degradation or dimensional changes due to moisture absorption.

Chemical Properties:
Excellent hydrolysis resistance, even under prolonged use in high-temperature and high-humidity environments, minimizing hydrolysis reactions and ensuring material stability. This makes them suitable for products in prolonged contact with water or humid environments, such as bathroom fixtures and water treatment equipment components.
Outstanding resistance to acid and alkali corrosion, with good tolerance to common acids, alkalis, and salt solutions. They are widely used in chemical and environmental protection industries for manufacturing chemical pipelines, valves, containers, and other equipment.
High chemical stability, with good resistance to most organic solvents and oils in addition to acids and alkalis. This makes PPSU materials highly adaptable in environments involving chemical exposure, such as laboratory equipment and pharmaceutical devices.
High flame retardancy (UL-94V0 rated), self-extinguishing properties, low smoke emission, and low toxicity during combustion, meeting fire safety requirements. They are suitable for applications demanding high flame retardancy, such as electronic and electrical equipment and building materials.
Good machinability, easily processed into various shapes and sizes via mechanical methods without 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 them ideal for manufacturing food processing equipment, tableware, baby bottles, and other products that come into direct contact with food.
High electrical insulation coefficient, excellent dielectric properties, and high insulation breakdown strength, making them superior insulating materials in the electronics and electrical fields for applications such as wire and cable insulation layers and electronic component encapsulation materials.

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