Application of Silicone Internal Release Agent in Products

For a long time, the product industry has been very cautious about the application of silicone internal release agents. This may have a significant impact on the different perspectives on understanding and using the product. People have always had the following misunderstandings about internal release agents: 

1 The impact on printed products can easily result in excessive wear resistance during printing. 

2. Foot pad adhesive products result in poor adhesion. 

3. The appearance of the product is prone to producing bright spots on the surface.

4. Easy to cause frosting.

Due to the above misleading information, people often miss opportunities and stop using it out of fear, resulting in the inability to fully utilize the performance of silicone release agents. In fact, long-term use of internal release agents can form a smooth film on the mold, which is easy to demold, especially for silicone products that are difficult to demold. Using good internal release agents can greatly help improve production capacity, but the effect cannot be seen in a short period of time. The experiment needs a reasonable cycle comparison. The rational use of silicone internal release agent depends on details, and the following elements need to be grasped: the selection of silicone raw materials should not be cheap. Even if the material is fine, cheap raw materials can still be unstable due to their short vacuum pumping and processing time. When selecting vulcanizing agents, only choose the right and trustworthy ones. If there are other substances with low purity, the product should not be cooked as quickly as possible, but as stable as possible. The sulfur addition time should not be too extreme. (Due to insufficient sulfur addition in the product, especially for those who choose fast vulcanizing agents, the surface is good, but the vulcanization curve is not yet complete, which may cause frosting and may not be the reason for internal detachment.) The dosage should be moderate. (It is only an auxiliary function, not the main function. The reasonable use of raw materials, auxiliary materials, and processing technology will reflect its value.)
