Sulfone Polymers Overview
Sulfone polymers are high-heat plastics with a clear advantage. These amorphous thermoplastics offer more toughness, strength and hydrolytic stability than other transparent plastics.
Sulfone polymers are high-heat plastics with a clear advantage. These amorphous thermoplastics offer more toughness, strength and hydrolytic stability than other transparent plastics. They withstand prolonged exposure to water, chemicals and temperatures – handling a broad range of end-use temperatures from -40°C to 204°C (-40°F to 400°F).
Udel® PSU – Rigid, high-strength, semi-tough, transparent plastic 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.
HDT of 174°C (345°F), Good practical toughness, Good chemical resistance.
Radel® PPSU – Delivers the highest performance of our sulfone polymers, offering better impact resistance and chemical resistance than polysulfone (PSU) and polyetherimide (PEI).
HDT of 207°C (405°F), Superior toughness and impact strength, Best chemical resistance, R-7000 Series for aircraft interiors.
Acudel® modified PPSU – A family of proprietary formulations that fill the cost-performance gap between PPSU and polysulfone (PSU).
HDT of 197°C (387°F), Better impact strength than PSU, Excellent long-term hydrolytic stability.
Veradel® PESU – Combines good chemical resistance with a high heat deflection temperature of 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
HDT of 204°C (399°F), Better chemical resistance than PSU, Inherently flame retardant.
Virantage® Tougheners – Comprehensive range of specialty polymers, oligomers and monomers in a variety of molecular weights and particle sizes. Product forms include powders, fibers and foams. High-temperature tougheners, Improves damage tolerance, Reactive end groups available.
