Influence of rubber compounding system on frosting

The cause of the frost from the formula, mainly the amount of these compatibilizers more than its saturated solubility due to the formula design, attention should be paid to the amount of sulfur and accelerator should be appropriate, should be strictly controlled by the vulcanisation, and to strengthen the control of free sulfur, or change to a good dispersion of varieties (eg, insoluble sulfur) and solubility of the good varieties. In addition, the appropriate addition of pine tar and gumarone resin in the rubber material can increase the solubility of the rubber material to the above mentioned cooperating agents, so it can reduce the phenomenon of frost spraying.
