Polyphenylsulfones formulated for cost effectiveness

Acudel® modified PPSU (polyphenylsulfone) is a family of proprietary formulations that fill the cost-performance gap between PPSU and polysulfone (PSU).

Acudel® grades provide toughness and chemical resistance along with excellent hydrolytic stability and dimensional stability, making them well-suited for plumbing system components with less demanding pressure and temperature requirements.

Acudel® 79000 is formulated specifically for use in aircraft cabin interior components and complies with stringent FAA regulations requiring low heat release, low smoke generation and low toxic emissions.
