韩国采购需求：球囊管、双层球囊管、三层管、多层管、内腔管、管材挤压

We're university students engaged in a national nanotechnology project, and we're in the final phase of creating our prototype for evaluation. Our presentation is set for September 23, but we need to wrap up our materials by September 11, so time is tight. We're looking for high-quality stent materials from your company to help validate our theoretical approach. If our prototype is successful and earns accolades, we plan to showcase your products in our presentation. Specifically, we're interested in fabricating a medical stent using ALD technology and need either a pre-treated stent or a flat substrate that we can work with. We're considering around 15 pieces of 2-inch x 2-inch size, either plain or treated. Additionally, could you share what materials are commonly used for vascular stents? That info would really help us in our decision-making. Looking forward to your swift response!
