Application and problems of medical silicone glue and platinum curing agent

Medical silicone glue is a category of silicone adhesives. In the same category, there are industrial grade silicone glue (low environmental protection, environmental pollution), military silicone adhesives (for new weapons, rockets and other high-tech products, the material performance is the most it is good). How much do you know about the application and problems of medical silicone glue and platinum curing agent?

At present, the pharmaceutical industry has long been used in silicone products, such as hospital silicone infusion tubes, various laboratory instruments, and the components implanted in the human body are silicone products. These silicone medical products do not require medical silicone water and platinum curing agent (also known as platinum water).

Of course, medical products have very strict requirements for glue or curing agents. Our products must also be tested at the medical level and certified at the food level. As far as the production of infusion tubes is concerned, our main raw materials are compounds and curing agents. This curing agent should be selected from non-toxic, odorless, food-certified platinum curing agent C-100A / B for processing and production. The characteristics of platinum curing agent anti-yellowing agent can maintain the color of the compound itself and is the only food certification SGS, FDA, ROSH related reports are widely used in medical product companies.

In the process of rubber mixing, there are often dead materials, this is for a reason:

Application and existing problems of medical silicone glue and platinum curing agent

1. The curing agent is a two-component material C≤100A / B, which is molded at a low temperature. Before mixing, component B must be added (comparative column is raw material: B: A = 1kg: 2G: 25g), otherwise AB is imported at the same time Or the first entry of A, B will cause death.

2. The mixed compound will be used up within 48 hours, otherwise it will die for a long time.

3. It should also be noted that when vulcanizing in hot air, due to the difference in vulcanization temperature conditions, attention should be paid to the selection of rubber compounds in the final selection of curing agent.

4. Platinum curing agent cannot be mixed with other vulcanized materials, because the composition of the two mixed vulcanized materials completely conflicts, resulting in failure of rubber refining.
