描述
Fortron 1200L1 is an unfilled, high melt viscosity polyphenylene sulfide (PPS) grade from Celanese Corporation, recommended primarily for extrusion applications . This specialty grade features high tensile elongation, offering significantly enhanced flexibility compared to standard unfilled PPS grades .
The high melt viscosity of Fortron 1200L1 provides excellent melt strength for extrusion processes, making it particularly suitable for producing sheets, films, and profiles . With a tensile elongation at break of 15% , this grade stands out for its ability to flex without breaking—a valuable property for demanding extrusion applications.
As a linear, semi-crystalline PPS, Fortron 1200L1 maintains the core advantages of the PPS family: outstanding chemical resistance to solvents, acids, bases, and automotive fuels below 200°C; high continuous use temperature (160°C to 240°C); inherent V-0 flame retardancy ; and extremely low moisture absorption (0.02%) . The material is RoHS compliant and available globally.

Critical Processing Warnings for Fortron 1200L1
⚠️ Drying Requirement – Fortron 1200L1 requires drying prior to processing. Predry at 110–120°C for 3–4 hours using a dehumidified air dryer with dew point ≤ -30°C . The time between drying and processing should be as short as possible.
⚠️ Moisture Control – Maximum residual moisture content should be ≤ 0.02% . Proper drying is essential to prevent void formation and ensure optimal product quality.
⚠️ High Melt Viscosity – This unfilled grade has high melt viscosity, providing excellent melt strength for extrusion. Processing parameters should be adjusted based on specific equipment and final product requirements .
⚠️ High Elongation Characteristic – With 15% elongation at break, this grade offers enhanced flexibility . This may require adjustment of take-off and handling equipment for extruded products to accommodate the higher stretch characteristics.
⚠️ Extrusion Equipment – Recommended processing conditions are similar to standard unfilled PPS grades. For injection molding, a three-section screw with 15–25 D length is recommended .
⚠️ Storage – Store in original, sealed packaging in a cool, dry place away from direct sunlight. For subsequent storage, the material should be stored dry until processed.
