COC-TOPAS 5013
Substituting optical glass and quartz in microfluidic chips, labware, and diagnostic cuvettes without compromising heat resistance during high-temperature PCR protocols requires an ultra-pure amorphous polymer, which Polyplastics’ TOPAS 5013S-04 Cyclic Olefin Copolymer (COC) delivers. Featuring a density of 1.02 g/cm³ and a glass transition temperature (Tg) of 130°C, this USP Class VI and ISO 10993 compliant resin provides 92% light transmittance, ultra-low birefringence, and a nearly non-existent moisture absorption of 0.01%. Jucheng Precision, under ISO 13485 certified medical frameworks, specializes in micro-molding TOPAS 5013. 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.

Biocompatible Process Configurations for Easy-Flow TOPAS 5013
With outstanding melt fluidity and amorphous stability, TOPAS 5013S-04 processes consistently inside microfluidic tools:
| 成形プロセス区分 | プロセス互換性と運用詳細 |
|---|---|
| 微流控芯片实验室 | Excellent. The primary process for TOPAS 5013. Optimized for multi-cavity, ultra-thin-walled medical diagnostics and biochips down to 0.1mm channels. |
| Precision Cuvettes & Microplates | Excellent. Highly compatible with high-speed automated runs, providing low-noise optical windows and excellent chemical-solvent resistance. |
| High-Accuracy Lenses & Optics | Excellent. Low dielectric constant and low birefringence are perfect for molding precise spherical lenses and optical diffusers. |
Optical Birefringence & Microfluidic Control Matrix
Molding an amorphous high-purity, easy-flow polymer like TOPAS 5013S-04 requires strict particulate controls and specialized tooling to prevent optical strain:
Low Birefringence & Stress Prevention
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 to prevent optical stress marks.
S136鏡面研磨金型（純度保持）
Any microscopic tool mark on core or cavity surfaces will scatter light and compromise optical clarity. We build molds using high-chromium S136 stainless steel, mirror-polished to a high level using clean diamond paste, ensuring non-porous biocompatible part surfaces with zero particulates.
加圧オイル金型温度制御
We maintain mold temperatures at 95°C–125°C (203°F to 257°F) using pressurized temperature controllers. High mold temperatures maximize surface gloss, reduce weld lines, and completely prevent weld-line stress cracking near intricate snap-fits.
Mandatory Desiccant Pre-Drying Protocol
Though COC absorbs virtually zero water, pre-drying raw material in clean-air desiccant hopper dryers at 100°C (212°F) for 6 hours is mandatory to prevent surface splay, dynamic micro-voids, and loss of transparent optical quality during high-speed runs.
