In the silicone industry manufacturers often encounter such problems, medical silicone rubber tube with what glue is good?
Silicone rubber strip extrusion molding and silicone rubber tube molding are well-known silicone rubber tube production technologies of many manufacturers, while how to choose a good glue for medical silicone rubber tube bonding, but many people don't understand, especially new manufacturers, will be particularly concerned when choosing glue.
Medical silicone rubber tube has high requirements in material selection, processing equipment, glue and other aspects. In industrial production, many seals are made of silica gel and silicone rubber, and silicone rubber strips are used in many places, such as electronic equipment components and silicone rubber household products. Silicone rubber materials have unique physiological inertia. Therefore, it has strong applicability in harsh environment. It is a strict requirement that medical silicone rubber tube and medical silicone rubber belt can be directly contacted in human body, skin, blood, body fluid and other places. Such as catheter, breathing mask, throat mask, balloon and other products.
After the production of medical silica gel hose, it will be bonded with other medical materials according to the needs of specific products, such as medical PVC, glass, PC, stainless steel metal, etc. Medical silicone rubber will be used.
There are three common types of medical silicone glue:
1. Single component translucent paste kj-998 and kj-998h are used for silica gel bonding and sealing.
2. Kj-998a and kj-998a-1 can be firmly adhered to the single cavity or double cavity silica gel laryngeal mask.
3. Medical silica gel development glue kj-998bl, usually single component blue and light blue silica gel glue, is commonly used in medical silica gel catheter, main purpose: to play the role of bonding, blocking, sealing, etc.
The above three medical silicone glue have one thing in common, that is, they must pass the FDA food level certification and ISO 10993 test (biocompatibility certification: cytotoxic biocompatibility, skin irritation biocompatibility, skin sensitization biocompatibility), which is also a method to determine the adhesive glue of medical silicone rubber tube.
