Polyphenylsulfone (PPSU)

FDM Thermoplastic

PPSU (also known as PPSF) offers elevated properties compared with commodity plastics. It is stronger than polycarbonate but its more notable features include heat and chemical resistance, which includes oils, gas and acids. FDM PPSU can also be sterilized using a variety of methods.

Key Attributes and Applications

Key Attributes

PPSU offers beneficial characteristics similar to high-performance plastics but without the associated higher cost.

Very good mechanical properties imparting strength, toughness, impact resistance, and dimensional stabilty.
Resistant to chemicals such as oils, gas, acids, and bases, making it suitable for industrial environments.
High thermal stability and heat resistance.
Can be sterilized using steam, plasma, autoclave, chemical, and radiation methods.

Key Applications

PPSU is suitable for applications that require broader durability than what standard engineering thermoplastics offer.

Functional prototyping for higher-stress, higher-heat scenarios.
Durable manufacturing tools that can withstand heat along with industrial chemicals and lubricants.
Limited production of parts that have high performance requirements but don’t need the capabilities of top-tier, high-cost polymers.
