Q1: What are the drying requirements for CYCOLOY™ C6600 PC/ABS before injection molding?
A: The material is prone to moisture absorption, which can cause silver streaks and bubble defects during molding. A dehumidifying dryer is recommended with a drying temperature of 80‑90℃ and a drying time of 3‑4 hours. The cumulative drying duration should not exceed 8 hours, and the maximum moisture content must be controlled below 0.04%. Once dried, the raw material should avoid prolonged exposure to air.
Q2: How to choose between CYCOLOY™ C6600 PC/ABS and general-purpose PC grades?
A: Neat PC offers higher heat resistance and room temperature impact strength, but lower melt flowability, making it more difficult to process thin-walled and complex parts. As a PC/ABS alloy, CYCOLOY™ C6600 provides better fluidity, a wider processing window, and flame retardancy, though its heat resistance is lower than neat PC. It is preferentially recommended for shell products that emphasize processing efficiency, high appearance aesthetics, and medium heat resistance requirements. Trial molding verification is recommended before mass production.
Q3: How to obtain UL flame retardancy and RoHS compliance documents for this grade?
A: CYCOLOY™ C6600 holds UL 94 series flame retardancy certifications. RoHS compliance statements must be requested from the raw material supplier as official SABIC reports. The technical data sheet cannot be used directly as compliance proof for finished product exports, and end products must complete regulatory testing in the target region prior to export.
Q4: Is CYCOLOY™ C6600 suitable for parts in long-term contact with chemical solvents?
A: This grade exhibits certain resistance to most household cleaners and greases, but is not resistant to strong organic solvents, strong acids, or strong alkalis. Long-term exposure to solvent environments may lead to stress cracking risks. Product designs should evaluate internal stress levels, and immersion testing is recommended in advance if the application involves chemical contact.
