2025-03-04

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.
