| Risk | Description | Mitigation | |------|-------------|------------| | | UV exposure can embrittle PVC over time. | Use UV‑stabilized additives or coat with UV‑blocking films. | | Fire rating | Standard PVC is flammable. | Opt for self‑extinguishing vinyl (e.g., FR‑PVC) or apply fire‑retardant coatings. | | Electrical interference | Conductive inks may unintentionally bridge circuits. | Design clear separation zones; test for dielectric breakdown. | | Regulatory compliance | Different regions have varying restrictions on PVC additives. | Source compliant grades (e.g., REACH‑registered) and maintain documentation. | | Recycling logistics | Mixed‑material assemblies can complicate recycling. | Design for monomaterial construction or provide clear disassembly instructions. |
