Solvay Specialty Polymers offers a comprehensive range of specialty polymers, oligomers and monomers in a variety of molecular weights and particle sizes for use in advanced composites. Product forms include powders, fibers and foams.
Sulfone Polymers for Composites
Virantage® polyethersulfone (PESU) – Amorphous, high-temperature thermoplastic that offers excellent thermal and hydrolytic stability. Inherent toughness imparts damage tolerance to thermoset composites and excellent flexibility to coatings.
Virantage® reactive polyethersulfone (r-PESU) – Features reactive end groups that enhance solubility and processability, and improve interfacial properties for excellent hot-wet performance in epoxy thermosets.
Solvay is creating a new PESU production site at its state-of-the-art facility in Panoli, India, as part of the company’s long-term commitment to supply and develop products specific to the composites industry.
Sulfone Monomers for Composites
Virantage® dichlorodiphenyl sulfone (DCDPS) – Ultra high purity monomer that serves as a key ingredient in the production of sulfone polymer-based tougheners.
Virantage® diaminodiphenyl sulfone (DDS) – Manufactured using DCDPS and is widely recognized as the hardener of choice for high-performance epoxies needing superior thermal and environmental properties.
Ultra Polymers for Composites
Torlon® polyamide-imide (PAI) – Reactive oligomer widely recognized for providing excellent adhesion to carbon, glass, aramid fibers and metals. This high-temperature material retains its outstanding cohesive and adhesive properties even under highly aggressive thermal and oxidative conditions.
AvaSpire® polyaryletherketone (PAEK) – Versatile family of polyaryletherketones (PAEK) that are tailored to provide new and unique combinations of performance and value.
KetaSpire® polyetheretherketone (PEEK) – Semi-crystalline polymer that offers outstanding chemical resistance for both thermoplastic and thermoset composite systems. Its proven long-term thermal and mechanical stability makes it an importantaddition to the traditional set of composite materials.
