What is PPSU Polymer

Tycoma PPSU GF25 LE (Polyphenylsulfone) is a 25% glass fiber-reinforced, V-0 flame-retardant thermoplastic. Its low extractables, high heat resistance, and mechanical stability make it a preferred material for medical devices, electrical and electronic equipment, and high-temperature industrial parts. When selecting a material, buyers must consider not only basic performance but also long-term reliability, processability, and supply chain stability. PPSU GF25 LE excels in these areas.

01 | Material Core Properties

It takes into account both mechanical properties and toughness

Polyphenylsulfone itself has good toughness, while glass fiber reinforcement provides high rigidity, ensuring that the parts will not crack when subjected to stress and impact. It is particularly suitable for parts with complex structures and thin walls.

Thermal performance and dimensional stability

The high heat distortion temperature and low coefficient of linear expansion enable PPSU GF25 LE to be used for a long time in high-temperature environments, maintain shape stability, and reduce the risk of failure caused by thermal cycling.

Low extract and safety

The low extract characteristics meet the strict hygiene requirements of medical devices, food contact parts, etc., while the flame retardant grade V-0 ensures the safety of electrical and high-temperature applications.

Chemical tolerance and environmental adaptability

It has a good tolerance to a variety of chemicals and disinfectants, is suitable for medical, chemical and high-temperature industrial environments, and can extend the service life of parts.

02 | Process Adaptation and Processing Guide

Processing Method: Ép phun

Processing Advantages: Excellent flowability, adaptable to complex geometries and thin-walled part designs.

Ghi chú: At high fill rates, mold temperature and injection speed must be optimized to balance molding accuracy and mechanical properties.

03 | Industry Application Analysis

Medical Devices

Low extractables and high heat resistance are suitable for syringes, surgical instrument handles, and sterilized reusable parts. V-0 flame retardancy ensures safe operation and meets FDA and ISO medical standards.

Electronic and Electronic Applications

High-temperature connectors, switch housings, and motor components require high insulation strength and heat resistance.PPSU GF25 LE's stable electrical properties and heat deflection temperature ensure increased reliability over long-term operation.

High-temperature industrial parts

For applications such as chemical equipment and corrosion-resistant structural components, PPSU GF25 LE offers high mechanical strength and dimensional stability, enabling it to withstand complex working conditions.
