用於軟塑料的新型生物相容性 UV 黏合劑

Panacol has developed a new plastic bonder that is certified to USP Class VI biocompatibility standards for medical device assembly applications. Vitralit^® UV 7030 features high elongation at break, excellent adhesion to difficult-to-bond plastics, and rapid curing under UV light.
Panacol 開發了一種新的塑料黏合劑，該黏合劑已通過 USP VI 等級生物相容性標準認證，適用於醫療設備組裝應用。 Vitralit® UV 7030 具有高斷裂伸長率、對難黏合塑料的優異附著力以及在紫外光下快速固化的特點。
 
The various material selections and pairings of flexible tubing and rigid connectors often create significant assembly challenges in high volume production.  Materials used to create infusion lines, catheters, and similar medical devices may include TPU, TPE, PEN, polyamides, Pebax^®, polycarbonate, ABS and PEEK. These thermoplastics and thermoplastic elastomers provide many desirable properties, but some combinations can be difficult to bond. After assembly, these materials are challenged by torsional stresses at the points of transition between the soft tubing and the hard connector.  Panacol developed the adhesive Vitralit^® UV 7030 to specifically address these complex issues.
在大批量生產中，軟管和剛性連接器的各種材料選擇和配對通常會帶來重大的組裝挑戰。用於製造輸液管線、導管和類似醫療設備的材料可能包括 TPU、TPE、PEN、聚酰胺、Pebax®、聚碳酸酯、ABS 和 PEEK。這些熱塑性塑料和熱塑性彈性體提供了許多理想的特性，但某些組合可能難以黏合。組裝後，這些材料在軟管和硬連接器之間的過渡點處會受到扭轉應力的挑戰。 Panacol 開發了黏合劑 Vitralit® UV 7030 來專門解決這些複雜問題。

Vitralit^® UV 7030 is a one-component, solvent-free UV curable acrylic adhesive.  It can be cured with light energy in the broad UV-A spectrum, or with LED systems that produce either 365 or 405 nm wavelength. This adhesive cures in seconds at layer thicknesses of a few 100 µm, ensuring high bond strength immediately after UV exposure. A key feature of Vitralit^® UV 7030 is its high elongation at break, >250%, combined with good tensile strength. When exposed to black light, Vitralit® UV 7030 fluoresces, which enables visual process control. Vitralit^® UV 7030 is certified to USP Class VI standards and suitable for typical sterilization processes including gamma, EtO and autoclave. 
Vitralit® UV 7030 是一種單組分、無溶劑紫外線固化丙烯酸黏合劑。它可以用寬 UV-A 光譜中的光能或產生 365 或 405 nm 波長的 LED 系統固化。這種黏合劑可在幾秒鐘內以幾百微米的層厚固化，確保在紫外線照射後立即具有高黏合強度。 Vitralit® UV 7030 的一個關鍵特性是其斷裂伸長率 >250%，以及良好的拉伸強度。當暴露在黑光下時，Vitralit® UV 7030 會發出熒光，從而實現可視化過程控制。 Vitralit® UV 7030 已通過 USP VI 級標準認證，適用於典型的滅菌過程，包括伽馬、EtO 和高壓滅菌器。
