Medical grade FEP heat shrink tubing in multi-layer catheters such as fusion spliced PU, PEBAX, and PA
The full name of FEP is Fluorinated ethylene replica, which is the best choice for various types of conduit welding due to the inherent temperature resistance, smoothness, and low shrinkage temperature of the material. The general guide tube is usually composed of a three-layer structure, namely the inner layer is PTFE (Teflon) inner layer, the middle layer is made of stainless steel wire weaving or spring coil structure, and the outer layer is made of Pebax material. At the same time, different hardness materials from the far and near ends are welded to form a complete catheter. The FEP heat shrink tube produced by Soko Medical is basically used to fuse three layers of different materials into a suitable tube body. It is precisely this sandwich structure design of inner lining, middle layer, outer layer, and surface coating that creates excellent universality of microtubules.
Among the clients we come into contact with, catheters with an outer diameter of ≤ 1.30mm are often referred to as microcatheters, which are used for wire support, exchange, and delivery of embolic agents, stents, etc. through lesions. The development trend of Minimally invasive procedure technology is to have less demand for pipe diameter and more innovative medical devices. The devices they use on blood vessels or other tissues require Catheter to have higher precision, stricter tolerance and additional functions. As conduit designs become increasingly complex, the products required to produce them also become smaller and thinner. This is another challenge for us, as we are confident in the field of ultra-thin and extremely small pipes due to their advanced production equipment.
The guide tube makes it easier for other instruments or instruments to enter the blood vessels, and is used to assist in the placement of lasers, stents, and balloons for angioplasty. The best guidance catheter support is crucial for successful interventional cardiac surgery. The ideal guide tube has a non-invasive soft tip, excellent torque control, sufficient support, and low surface friction resistance, making the instrument have good traceability. There is a clear difference between the guidance catheter and the contrast catheter:
The role of a guiding catheter is to introduce therapeutic devices such as wires, balloons, and stents, with more emphasis on guiding treatment; The function of the contrast catheter is mainly to inject contrast agent into the coronary artery, playing a diagnostic role. Compared with contrast catheters, guide catheters have higher manufacturing requirements. When the outer diameter is the same, the inner cavity is required to be larger, making it easier to accommodate devices such as guide wires, balloons, and stents. In addition to imaging catheters and guidance catheters used for the heart, there are also some used for nerves, blood vessels, abdominal aorta, uterine artery, etc.
The following materials are preferred:
Conduit materials: Pebax, PTFE, nylon, FEP, PU, HDPE, ETFE
Wire type: Round, Flat, Hybrid (Round&Flat)
Wire material: stainless steel, nickel titanium alloy, copper, PEEK, nylon
Weaving style: diamond weaving, regular weaving, semi weaving, coil weaving
Other common products: imaging catheter, balloon catheter, braided catheter assembly, extension catheter, guide sheath and dilator PTFE catheter, intravenous indwelling catheter, insulin delivery catheter, peripheral intervention catheter.
Aokeray FEP heat shrink tube
AOKERAY FEP heat shrink tubing is made of modified fluorinated ethylene propylene, which is transparent and semi rigid. It is a standard application in the conduit shaft and adhesive joint industry. For AOKERAY FEP, we can control vertical growth by ± 5% to ensure consistency between batches, reduce waste, and reduce costs.
FEP heat shrink tubes provide products with shrinkage rates of 1.3:1, 1.6:1, and 2:1. These heat shrink tubes adopt the same high standard characteristics as our other heat shrink tube products, and the supplied products are in an expanded state. After brief heating, they will be tightly wrapped and shaped on complex irregular product forms, forming a completely enclosed and sturdy cover. From the Heat gun to the welding machine, heat shrinking can be completed by many methods (but the welding machine can provide the most uniform shrinkage effect). We can provide micro dimensions and customize specifications and tolerances according to requirements.
The FEP heat shrink tube jacket can extend the service life of the covered components, as it can provide protection in extreme conditions such as high temperature, high humidity, corrosion, and impact, providing a tight and protective packaging for various components. It has high Dielectric strength and chemical inertia. In the medical field, FEP heat shrink tubing is an ideal manufacturing aid during the rheological forming of catheter jackets, which can be easily removed afterwards. FEP heat shrink tubing can fully meet your requirements! .more size and free sample fep heat shrink tube fast inquire
