Medical device adhesive solution
Medical grade glue provides an indispensable solution for the special-shaped assembly and rapid assembly of medical devices, but the particularity of medical devices not only requires materials to meet human health requirements (ISO 10993 or USP Level 6 certification), At the same time, it must be suitable for high precision production and permanent bonding and suitable for disinfection methods such as autoclaving, gamma-ray sterilization and ethylene oxide sterilization. This puts forward higher requirements for the performance of medical glue, and choosing the right adhesive product is a problem that every medical device manufacturer must face.
Medical grade glue is widely used in disposable medical products and medical testing equipment, such as syringe needles, hemodialysis filters, blood bags, endoscopes, breathing masks, CT testing equipment and so on. These medical products are usually made of a variety of synthetic materials or metals, including commonly used PC, ABS, PVC, TPU, stainless steel, but also including difficult to bond plastics such as PEEK, PE and PP. Medical grade glue can be divided into:
| Glue type | Cyanoacrylate instant drying glue | Silicone adhesive | Epoxy glue | Acrylic adhesive |
| Merits and demerits | Relying on the moisture in the air express curing, it has a good bonding effect on most materials, but there are problems of moisture resistance, water resistance and poor temperature resistance. | Good elasticity, has a good bonding effect on silicone materials, depends on moisture curing in the air or UV light/moisture curing double curing, but its own strength is low. | It has a good bonding effect on most materials, and can be cured at room temperature or heated, and some products can be cured by UV light. | Acrylic adhesive for medical use is generally UV light curing system, high viscosity and hardness selectivity, strong versatility. |
UV light curing medical grade glue, its advantage is that under UV light irradiation conditions, online fast curing,according to the material composition can choose acrylic type, silicone type and epoxy type products.
| UV adhesive type | Acrylic UV adhesive | Silicone UV adhesive | Epoxy UV adhesive | Cyanoacrylate UV adhesive |
| advantage | Fast curing, good choice of viscosity and hardness. | Elastic, silicone material has a good bonding effect, most of the moisture can be cured twice. | It has a good bonding effect on a variety of materials, and can be recured for parts not exposed to UV light. | UV light curing combined with moisture curing, for most materials and very little bonding effect. |
| Inferior position | The parts not exposed to UV light will not cure. | The strength itself is low. | The available product models are too few. | Moisture resistance is slightly poor. |
