1. Avoid the occurrence of bubbles in the vulcanization process of rubber fender and improve the density of rubber material.

When vulcanized, the rubber material includes water and other volatile substances, as well as hydrogen sulfide gas that can be formed in the vulcanization reaction, and the rubber material is volatilized and escaped at low temperatures. If the vulcanization pressure is greater than the vulcanization pressure that the rubber can escape, the attack of bubbles can be avoided, and the density of the rubber can be improved.

2. Make the rubber fender compound easy to move and fill the mold cavity

In order to produce clear and plump rubber products, it is necessary to make the rubber material can move and fill the mold cavity. In particular, the effect of vulcanization pressure is more clear when the rubber is in the vulcanization induction period of uncrosslinked shape. The experiment shows that if the vulcanization temperature of molded rubber products is 100-140℃, the vulcanization pressure should be in the range of 2-4.9MPA.

3. Improve the adhesion of rubber fender material and cloth layer

During vulcanization, with the addition of vulcanization pressure, the depth of rubber penetration into the cloth layer increases, so as to improve the adhesion of rubber and cloth layer and the flex resistance of rubber fender.
