Main Types And Applications of Medical Adhesives

Medical grade adhesives refer to adhesives used for bonding medical devices. Common types of adhesives used in medical applications include:

1. Cyanoacrylate Adhesives

Advantages: Acrylic adhesives are suitable for a wide range of bonding materials, have a fast curing speed, and have excellent bonding performance with plastics.

Application range: Commonly used in catheter components, delivery tube bonding, polyolefin bonding, etc.

2. Light-curing acrylic adhesive

Advantages: It can be widely used in various bonding materials, has outstanding chemical resistance, and the curing speed can be adjusted according to requirements.

Application range: Commonly used for injection needle assembly bonding, anesthesia mask application, heat exchanger, oxygenator and delivery tube bonding, etc.

3. Epoxy resin adhesive

Advantages: Epoxy resin adhesives can be widely used on various substrates, with outstanding heat resistance and chemical resistance. Epoxy resin itself has low shrinkage, good gap filling ability and bonding performance.

Application range: Epoxy resin adhesives are commonly used in various potting glues, injection needle assembly, etc.

4. Polyurethane Adhesives

Advantages: It is suitable for a wide range of bonding materials and has excellent peel resistance, impact resistance and weather resistance.

Application range: Polyurethane adhesives are suitable for potting and device pin tip bonding.

5. Silicone Adhesives

Advantages: Silicone has high peel strength, good heat resistance and good elongation at break. Silicone adhesives are also widely used in medical applications.

Application range: Bonding and sealing of silicon substrates, surface coating of extremely flexible substrates.
