Four reasons for the problem of difficult exhaust of silicone products

1. If the exhaust distance is too large or too short, it should be strictly controlled between 1-5cm;

2. If the first exhaust is not exhausted, a second exhaust can be carried out to solve the problem;

3. It has not reached the vulcanization time;

4. There are problems with the rubber material, such as uneven dispersion of moisture/vulcanizing agent/uneven mixing of the rubber material.
