Bubbles On The Surface Of Rubber Products

1. There is water (add calcium oxide when mixing);

2. Not fully vulcanized, unappreciated and appears to have bubbles;

3. There are many impurities in the vulcanizing agent, impurities of small molecules become decomposed in advance, and bubbles remain in the product;

4. The exhaust design of the mold itself is unreasonable, and the gas cannot be discharged in time when the rubber material strikes the line.

5. Poor dispersion;

6. Plastic compounding takes a long time and there are bubbles when the product is vulcanized.
