Medical-grade adhesives refer to adhesives that can be used for bonding medical devices
Medical-grade adhesives refer to adhesives that can be used for bonding medical devices, generally using industrial adhesives. Common medical-grade adhesives include the following:
I. Cyanoacrylate Adhesives
Advantages: Acrylates have a wide range of applicable bonding materials, fast curing speed, and excellent bonding performance, especially with plastics.
Applications: Commonly used in catheter components, tubing bonding, and polyolefin bonding.
II. Photocurable Acrylate Adhesives
Advantages: Widely applicable to various bonding materials, with outstanding chemical resistance and adjustable curing speed as required.
Applications: Commonly used in injection needle assembly bonding, anesthesia mask applications, heat exchangers, oxygenators, and tubing bonding.
III. Epoxy Adhesives
Advantages: Epoxy adhesives can be widely used for various substrates, with outstanding heat resistance and chemical resistance. Epoxies themselves have low shrinkage, good gap-filling ability, and bonding performance.
Applications: Epoxy adhesives are commonly used in various potting compounds and injection needle assembly.
IV. Polyurethane Adhesives
Advantages: Applicable to a wide range of bonding materials, with excellent peel strength, impact resistance, and weather resistance.
Applications: Polyurethane adhesives are suitable for potting and device needle tip bonding.
V. Silicone Adhesives
Advantages: Silicone has high peel strength, good heat resistance, and good elongation at break. Silicone adhesives also have wide applications in medicine.
Applications: Bonding and sealing of silicone substrates, surface coating of extremely flexible substrate materials.
