Thermalux is Westlake’s family of sulfone polymers. These amorphous thermoplastics are known for their toughness and stability at broad range of end-use temperatures from -40°C to 204°C (-40°F to 400°F). Thermalux polymers are used in specialty applications and often are a superior replacement for polycarbonates. Three types of Thermalux are commercially available: polysulfone (PSU), polyethersulfone (PESU), and polyphenylsulfone (PPSU).

Thermalux PSU
Thermalux PSU
Thermalux Polysulfone (PSU) is an amber colored, semi-transparent, heat-resistant, high performance engineering thermoplastic that offers higher heat resistance and better hydrolytic stability than polycarbonate (PC). It retains its good mechanical properties when exposed to steam and other sterilization techniques.
-
Thermalux PPSU
Thermalux PPSU
Thermalux Polyphenylsulfone (PPSU) is a high performance engineering thermoplastic that offers a superior combination of high performance properties that include excellent thermal stability (HDT of 207°C / 405°F), outstanding toughness, and good environmental stress cracking resistance.

Thermalux PESU
Thermalux PESU
Thermalux Polyethersulfone (PESU) An amber colored, semi-transparent, high performance engineering thermoplastic that combines good chemical resistance with a high heat deflection temperature (204°C / 399°F), making it a good fit for food service applications. This resin is also inherently flame retardant for use in electronic components and testing devices.
