About Solef® 31508

Solef® 31508 Flexible PVDF Copolymer

Solef® 31508 is a flexible VF2-CTFE PVDF copolymer engineered for applications requiring improved low-temperature flexibility and enhanced ductility compared to standard PVDF homopolymers. Its copolymer structure supports flexible processing behavior and durable mechanical performance while maintaining the chemical resistance, thermal stability, and environmental durability associated with PVDF materials. Solef® 31508 is well suited for industrial applications operating in harsh or low-temperature environments where both flexibility and long-term fluoropolymer reliability are important.

Primary Applications

LOW-TEMPERATURE FLEXIBLE COMPONENTS
VF2-CTFE copolymer structure supports improved flexibility and durable mechanical performance in low-temperature operating environments.

FLEXIBLE EXTRUSION APPLICATIONS
Suitable for extrusion processes requiring a balance of fluoropolymer durability, ductility, and low-temperature flexibility.

CHEMICAL-RESISTANT FLEXIBLE SYSTEMS
Applicable in industrial systems exposed to aggressive chemicals or harsh environments requiring both corrosion resistance and flexible material behavior.

SPECIALTY INDUSTRIAL FABRICATION
Well suited for fabricated PVDF components requiring enhanced flexibility and dependable long-term performance under demanding operating conditions.

Secondary Applications

WIRE & CABLE MATERIALS
Useful in specialty insulation and jacketing applications requiring flexibility, dielectric performance, flame resistance, and environmental durability.

OUTDOOR & HARSH ENVIRONMENT APPLICATIONS
Applicable in systems exposed to environmental stress, weathering, or temperature extremes requiring long-term fluoropolymer stability.

LOW-STIFFNESS INDUSTRIAL SYSTEMS
Suitable for industrial applications requiring reduced rigidity and improved ductility compared to standard PVDF homopolymer grades.
