COP-Zeon Zeonor 1420R
Replacing optical glass and quartz in high-precision pre-filled syringes, diagnostic cuvettes, and microfluidic chips without introducing chemical extractables or leachables requires an ultra-pure amorphous polymer, which Zeon’s Zeonor 1420R Cyclic Olefin Polymer (COP) delivers. Featuring an extremely low density of 1.01 g/cm³ and a glass transition temperature (Tg) of 136°C, this USP Class VI and ISO 10993 certified resin provides 92% light transmittance, exceptionally low birefringence, and nearly non-existent water absorption (less than 0.01%). Jucheng Precision, under ISO 13485 certified medical frameworks, specializes in micro-molding Zeonor 1420R. Supported by certified ISO Class 7/8 cleanrooms and in-house 5-axis CNC-machined S136 stainless steel tooling, we guarantee zero-particulate contamination and pristine detail replication verified by Zeiss CMM.
Zeonor 1420R Optical Purity & Biocompatibility Profile
Zeonor® 1420R is an unreinforced amorphous Cyclic Olefin Polymer (COP) resin engineered by Zeon Corporation, certified to deliver outstanding optical clarity, extreme purity, and low water absorption under ISO/ASTM standards:
| Clinical Quality Factor | Zeonor 1420R Value | Lợi ích Linh kiện Công nghệ Y tế |
|---|---|---|
| Optical Transmittance | 92.0% Light Transmission & Low Birefringence | Delivers glass-matching transparency directly from polished core cavities, preventing light diffraction errors in analytical diagnostics. |
| Ultra-Low Extractables | USP Class VI & ISO 10993 Certified | Highly purified amorphous matrix ensures zero toxic leachables, protecting sensitive pre-filled therapeutic drug storage. |
| Extreme Hydrophobicity | Water Absorption Less Than 0.01% | Virtually non-hygroscopic. Excludes environmental moisture swelling, preventing micro-volume microfluidic channel errors. |
Precision Micro-Molding Configurations for COP Zeonor 1420R
With its high-flow melt index and amorphous stability, Zeonor 1420R processes consistently inside precision cavities:
| Molding Process Category | Process Compatibility & Operational Details |
|---|---|
| Microfluidic Lab-on-a-Chip | Excellent. The primary process for Zeonor 1420R. Optimized for multi-cavity, ultra-thin-walled medical diagnostics and biochips down to 0.1mm channels. |
| Pre-filled Syringes & Vials | Excellent. High toughness, low outgassing, and excellent steam autoclaving resistance prevent dimensional distortion in medical syringes. |
| High-Fidelity Optical Lenses | Good. Outstanding dimensional stability, low outgassing, and ultra-low birefringence prevent structural warping in smart camera lenses. |
Hướng dẫn Gia công & Đúc trong Phòng sạch ISO 13485
Molding an amorphous high-purity medical-grade polymer like Zeonor 1420R requires strict control of parting lines to prevent flash, alongside cleanroom contamination control:
Đúc Phun trong Phòng sạch ISO Class 7/8
Medical-grade COP resins must be protected from any airborne particulates or dust. Jucheng operates dedicated injection molding machines inside fully enclosed, positive-pressure ISO Class 7/8 cleanrooms. Raw material feeding, plastication, and robot part-ejection are completely automated and isolated.
Khuôn S136 đánh bóng gương (Bảo toàn độ tinh khiết)
Để ngăn ngừa kích ứng mô do độ nhám bề mặt vi mô, chúng tôi chế tạo khuôn bằng thép không gỉ S136 hàm lượng crom cao. Các khoang được đánh bóng gương đến mức cao bằng bột kim cương sạch, đảm bảo bề mặt chi tiết tương thích sinh học không xốp, không có vết kéo nhả động.
Low Birefringence & Thermal Stress Control
High melt shear during injection causes internal molding stresses, resulting in birefringence (rainbow refraction effects). Jucheng’s tooling division uses 5-axis CNC machines to cut precise runner geometries, applying slow, uniform packing pressures and keeping mold temperatures at 80°C–120°C (176°F to 248°F) using pressurized temperature controllers.
Quy trình sấy khô bằng chất hút ẩm mở rộng
Though COP absorbs minimal water, pre-drying raw material in clean-air desiccant hopper dryers at 110°C (230°F) for 4 hours is mandatory to prevent surface splay, dynamic micro-voids, and loss of transparent optical quality during high-speed runs.
