Medical-Grade Products for Medical Use

Biocompatibility is the ability of a material to NOT cause an immunological response or interact with human tissue. Material that is to be used within medical applications are tested according to certain standards and are ultimately recommended for evaluation for certain types of use. Biocompatibility testing is performed according to certain standards wich can result in different medical grades.

Find High-Quality Medical Materials

Here you will find medical-grade products that meet the stringent requirements of the medical industry. We offer a wide range of medical silicone, medical UV adhesives, and medical epoxy. These products are tested for biocompatibility and are suitable for various medical applications.

Biocompatibility and Classifications

Biocompatibility refers to a material's ability to not elicit an immunological response or interact with living tissue. Materials intended for medical applications are tested according to various standards and recommended for specific uses. The two primary standards for medical use are USP Class VI and ISO-10993.

• USP Class VI: An older and less stringent classification.
• ISO-10993: A more comprehensive standard that includes various tests to ensure safety.

Within these standards, various tests are conducted, such as hemolysis, cytotoxicity, sensitization, and implantation. More information about specific tests can be found from the respective manufacturers. Please feel free to contact us if you need assistance.

Medical Adhesives and Their Applications

Medical adhesives are also categorized within these classifications into two recommended usage conditions:

• Implantable for up to 29 days
• Implantable for over 29 days

Our Range of Medically Approved Materials

Among our medically approved materials, you will find:

UV Adhesives

Dymax offers a range of UV-curable acrylate adhesives used in various applications within single-use medical devices. Applications include needle bonding and catheters. Please note that implantation is not recommended for more than 14 days. The advantages of UV-curable adhesives include a quick and easy process without solvents.

Medical Silicones

Nusil provides medically classified silicones of various types: adhesives, coatings, LSR, HCR, and medical lubricants. There are also silicone materials that are implantable for over 29 days.

Medical Epoxy

Epo-Tek has a selection of medically classified epoxy products, including optical adhesives and thermally and electrically conductive variants. UV adhesives based on epoxy are also available.

Cyanoacrylate / Instant Adhesives

Cyanoacrylate adhesives are a good choice for smaller applications such as single-use items and instruments in medical environments.

What type of sterilization is suitable?

Medical adhesives and silicones are often developed to be able to withstand commons sterilization methods such as gamma radiation, EtO, autoclave and E-beam. Many factors can influence the results and it is therefore important to verify the method for the specific material and application in question. Generally, it can however be said that:

Lim	EtO	Gamma/E-Beam	Autoklav
UV-akrylat (Dymax)	Compatible1	Compatible2	Not recommended
Silikon (Nusil)	Compatible3	Compatible4	In some cases1
Epoxi (Epo-Tek)	Compatible	Compatible4	Compatible
Cyanoakrylat (Permabond)	Compatible	Compatibe	Not recommended

1. Possibly slightly lowered adhesion.
3. Wait at least 24 hours after sterilization before use.
4. May induce small changes in mechanical properties (primarily durometer and flexibility) and discolouration.
