Why do bubbles appear when using platinum vulcanizing agent for vulcanization_ What is the reason for this
Mar 31,2023 Hanast
Most of the various silicone products commonly used in daily life are made using the vulcanization process. The rubber blend is vulcanized by adding a vulcanizing agent, and there are several types of silicone products, such as dual 24, dual 25, and platinum vulcanizing agents, which are used for various products with different requirements. Recently, I have seen many customers reflect on why there are bubbles when platinum vulcanizing agents are vulcanized, and which link has the problem? The following editor will tell you the reasons why these situations may occur.
Bubbles appear during vulcanization of platinum vulcanizing agent
Why do platinum vulcanizing agents cause bubbles during vulcanization? Bosses should pay more attention to the following aspects.
1. Excessive cross-linking agent: Excessive cross-linking agent will largely cause rubber bubbles;
2. Excessive catalyst and rapid vulcanization;
3. The water content of the rubber is too high;
The above three points are the main reasons for the occurrence of bubbles. Have you understood them? How can we solve this situation.
Several Methods to Solve Bubbles in the Sulfuration Process
1. Controlling the water content of the rubber compound;
2. Properly reduce the amount of Agent B added, and if bubbles still appear, appropriately reduce the amount of Agent A added.
