PC Covestro 2407
Material Introduction: PC Covestro 2407 is an injection‑molding grade polycarbonate material with outstanding performance. It is famous for favorable flowability, good mold‑release property, UV‑stabilized performance and general‑purpose applicability. Its good impact resistance and heat resistance satisfy the requirements of numerous application scenarios. Built‑in mold‑release agent and UV stabilizer improve processing convenience and outdoor service durability.
Main Applications
- Electronic & Electrical Components: Household‑appliance housings, switches, sockets, wiring boards, capacitors and other parts.
- Automotive Parts: Lamp housings, interior trim parts, instrument‑panel components (verify whether heat resistance meets specific requirements).
- Industrial Equipment & Parts: Protective covers, frames, gears, bearings for mechanical equipment.
- Consumer Goods & General‑Purpose Parts: Toys, models, tableware (food‑contact certification to be verified), LED lamp housings and other products.
