1. Insufficient vulcanization of products, resulting in large bubbles on the surface of rubber products, cut open its internal honeycomb sponge.
2. Poor rubber-metal bonding will cause a large amount of gas residue in the bonding area, gas contraction when pressurized. Once the pressure is removed, the gas diffusion, the rubber layer is thin and large area between the rubber and metal will appear bubbles
3. There is gas wrapped into the rubber, the gas is not easy to exclude, with the rubber together with the vulcanization, thus appearing on the surface of the product bubbles
4. There are volatile substances in the formula of rubber material.
