Manufacturers in the silica gel industry often encounter such a problem, medical silica gel tube what glue is good for bonding? First of all, silicone rubber strip extrusion molding, silicone tube molding is a familiar technology for many manufacturers of silicone tube production, and medical silicone tube bonding how to choose a good glue, but many people do not understand, especially new manufacturers, in the choice of glue will be particularly worried.
Medical silica gel tube in material selection, processing equipment, glue and other aspects of high requirements. In industrial production, many seals are made of silicone and silicone rubber materials, and there are many places where silicone rubber strips are used, such as electronic equipment components and silicone rubber household products. Silicone rubber material has a unique physiological inertia. Therefore, the medical silicone tube, medical silicone rubber belt, which can be in the human body, skin, blood, body fluids and other places directly contact is a relatively strict requirement. Such as catheter, breath mask, throat mask, balloon and other products.

After the production of medical silicone hose, it will be bonded with other medical materials according to the needs of specific products, such as medical PVC, glass, PC, stainless steel, etc. Medical silicone rubber will be used then.

There are three common medical silicone glues:

1. Single-component semi-transparent paste KJ-998 and KJ-998H, used for silica gel bonding and sealing.

2. Kj-998a and KJ-998A-1 can be firmly adhered to single or double chamber silicone laryngeal mask airway.

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, mainly used for bonding, blocking, sealing and other functions.

All three medical silicone glues have one thing in common: they must pass FDA food certification and ISO 10993 (biocompatibility certification: cytotoxic biocompatibility, skin irritation biocompatibility, skin sensitization biocompatibility), which is one way to determine the adhesive glue for medical silicone tubes.
