描述

Fortron FX650T6 is a 50% glass-fiber and mineral reinforced polyphenylene sulfide (PPS) injection molding grade from Celanese Corporation with improved impact and heat shock resistance . This grade is designed to address the brittleness of standard high-filled PPS grades while maintaining exceptional stiffness, strength, and heat resistance .

With 50% glass and mineral reinforcement, Fortron FX650T6 delivers outstanding mechanical performance including a tensile modulus of 12,200 MPa and tensile strength of 130 MPa . The impact modification provides enhanced toughness and thermal shock resistance—the ability to withstand rapid temperature changes without cracking—making it ideal for demanding automotive and industrial applications .

As a linear, semi-crystalline PPS, Fortron FX650T6 provides high dimensional stability, low coefficient of friction, low shrinkage (0.3% parallel, 0.5% transverse), excellent mechanical properties, creep resistance at high temperatures, and very low moisture absorption (0.07%) . The material exhibits excellent chemical resistance to all solvents below 200°C, acids, bases, automotive fuels, and petroleum fluids at elevated temperatures.

Critical Processing Warnings for Fortron FX650T6

⚠️ Drying Requirement – Fortron FX650T6 requires drying prior to processing. Because of the necessary low maximum residual moisture content, the use of dry air dryers is recommended. 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 part quality.

⚠️ Melt Temperature – The recommended melt temperature range is 310–340°C, with an optimum of 330°C . Avoid exceeding 340°C to prevent material degradation.

⚠️ Impact Modified Grade – This grade is specifically formulated with impact modifier for improved impact and heat shock resistance . Processing parameters should be optimized to maintain impact modification performance.

⚠️ Thermal Shock Applications – Fortron FX650T6 is specifically designed for improved heat shock resistance . Ensure proper part design to maximize performance under thermal cycling conditions.

⚠️ Automotive Specification – Fortron FX650T6 meets STELLANTIS B62 0300 61/222E/220M+/C2B/C5 specification . Ensure proper part design to meet automotive quality requirements.

⚠️ 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 .
