Features & Benefits
Superior Thin-Wall Flame Retardancy
This Cycoloy CM6140 (PC/ABS) resin achieves a UL94 V-0 rating at just 0.8mm thickness. This allows you to design lighter, thinner, and more aesthetically pleasing components for electronics without compromising safety.
Halogen-Free & Mineral-Filled Safety
As a non-chlorinated/brominated material, it meets evolving environmental regulations. The mineral-filled system provides reliable flame retardancy, making it a responsible choice for consumer-facing and regulated products.
Excellent Processability and Toughness
FR Resins CM6140 combines high flow for easy filling of complex molds with good ductility and impact strength. This results in higher manufacturing yields and durable end-products that resist failure.
Use & Applications
- Thin-wall components for consumer electronics
- Internal structures and housings requiring flame retardancy
- Parts where a high stiffness-to-flow ratio is critical
