Chi Mei Wonderlite PC – 115 Hot Sale PC Resin

Chi Mei Wonderlite PC-115 is a low-viscosity, general-purpose polycarbonate (PC) resin manufactured by Chi Mei Corporation.

Density: Measured according to ISO 1183, the density is 1.20 g/cc (0.0434 lb/in³). This density value is a fundamental property that affects the material’s weight and volume – related performance.
Melt Flow: Tested at a load of 1.20 kg and a temperature of 300 °C, following the Melt Volume Rate (ml/10 min) method in ISO 1133, the melt flow rate is 15 g/10 min.

Base Material: Polycarbonate (PC)
Modification Features:
- Good optical clarity, allowing for applications where transparency is desired.
- High impact resistance, providing durability in various environments.
- Excellent heat resistance, enabling use in temperature – sensitive applications.
- Suitable for injection molding processes.
- Low viscosity, facilitating easy flow during processing.

1. External Pen Tubing (Stationery)
- Application Context: PC-115’s low viscosity (MFI ~15 g/10 min) and high transparency make it ideal for injection-molded pen barrels, which require clarity for aesthetic appeal and durability for repeated use.
2. Transparent Toy Components
- Application Context: PC-115’s FDA compliance, impact resistance, and clarity make it suitable for transparent toy parts, such as action figure accessories or building blocks, requiring safety and durability.
3. Optical Covers (e.g., LED Covers, Display Windows)
- Application Context: PC-115’s excellent optical properties and dimensional stability are ideal for injection-molded optical covers, such as LED lamp covers or display windows, requiring high clarity and durability.

Injection Molding:
- Melt Temperature: 270–300°C to optimize flowability (MFI ~15 g/10 min) for thin-walled parts.
- Mold Temperature: 70–90°C to reduce internal stresses and enhance clarity.
- Injection Pressure: 80–110 MPa to fill complex molds without defects.
- Drying: Dry resin at 120°C for 4 hours to eliminate moisture and prevent bubbles.
Post-Processing: Anneal parts at 110–120°C for 1–2 hours to relieve residual stresses, especially for thin-walled or transparent components.

UV Stability: PC-115 is not UV-stabilized (unlike PC-110U). For outdoor applications, apply UV-resistant coatings or select PC-110U.
Flame Resistance: The UL 94 V-2 rating may not suffice for applications requiring higher flame retardancy (e.g., V-0). Consider PC-6710 for such needs.
Chemical Resistance: PC-115 has limited resistance to harsh chemicals (e.g., solvents, oils). Avoid applications with prolonged chemical exposure.
Cost: Polycarbonate is more expensive than alternatives like ABS or PP. Justify its use for applications requiring transparency and impact resistance.
