High Temperature Resistance, High Fluidity, Halogen-Free Flame Retardant: Read This One Article to Understand SABIC CY6414-701

PC/ABS alloys, leveraging their comprehensive performance advantages, have become fundamental materials in sectors such as electronics, electrical appliances, automotive, and lighting. In 2026, China's engineering plastics market reached RMB 89 billion, with PC/ABS accounting for 18% of the share. Among them, SABIC's CYCOLOY™ series has consistently held the technological high ground. This article focuses on the star grade of this series – CY6414-701 – analyzing why it has become the preferred solution for engineers.

I. Material Positioning

CY6414-701 belongs to SABIC's CYCOLOY™ product line and is an alloy of polycarbonate (PC) and ABS resin. This grade adopts a halogen-free flame retardant system (non-brominated, non-chlorinated), balancing high performance with environmental safety, meeting increasingly stringent global regulatory requirements.

II. Three Core Properties

1. High Temperature Resistance, Dimensional Stability

Heat Deflection Temperature (1.8MPa) of 118°C and Vicat Softening Temperature of 135°C, capable of handling heat buildup inside electronic devices. The linear thermal expansion coefficient is as low as 7E-05 cm/cm/°C, maintaining precise dimensions across a temperature range of -40°C to 40°C, ensuring stable and reliable performance even in extreme environments.

2. High Fluidity Combined with High Impact Resistance

Melt Flow Rate (260°C/5.0kg) reaches 14g/10min, allowing smooth filling of thin-wall and complex mold cavities. Balanced mechanical properties: tensile modulus of 2330MPa, yield tensile strength of 64.0MPa, and elongation at break >100%. At room temperature, Charpy notched impact strength is 28kJ/m², and Izod notched impact strength is as high as 800J/m; even at -30°C, impact strength remains above 12kJ/m², offering both rigidity/toughness and low-temperature ductility.

3. Environmentally Friendly Flame Retardancy, Safety Assured

Chlorine-free and bromine-free flame retardant system, UL 94 certified: V-0 at 1.2mm and 5VB at 2.5mm. Limiting Oxygen Index of 32%, Glow Wire Ignition Temperature of 775°C (0.75-3.0mm), and Glow Wire Flammability Index of 960°C. High safety margin for electrical applications, effectively reducing fire risk.

III. Typical Applications

• Electrical/Electronics: Commercial equipment enclosures, TV housings, computer/notebook casings, copiers, printers, and other OA equipment.

• Automotive: Instrument panels, trim pillars, instrument cluster covers, grilles, and other interior/exterior trim components.

• Lighting: LED lamp housings, benefiting from heat resistance and flame retardancy advantages.

IV. Processing Key Points

PC/ABS is sensitive to moisture. Thorough drying is required before molding: 90-110°C for 2-4 hours, achieving moisture content <0.04%. Strictly control molding temperature and high-temperature residence time to avoid thermal degradation. Proper processing is key to realizing the performance of CY6414-701.
