Table 3 shows that, since magnesium oxide is added, to improve the degree of crosslinking, causing reduced EL, adding volume, the more reduced, it was added to 8 parts, with the increase of added amount, EL but instead increases. That magnesium oxide 5 parts or less, the crosslinking is, 8 parts 8 parts above or both active role in promoting the degree of EVA foam manufacturer. Appearance of 0 and 11 were the best. Best compression to 11 parts.

2.4 promoter of NA-22

Parts of magnesium oxide is 0, TAC of 1 part, EVA foam manufacturer agent 64 to 9 parts, DCP variables investigated accelerator NA-22 on the experimental results, the results shown in Table 4. From Table 4, the curing system, without magnesium and accelerators NA-22, they can be vulcanized, is not said previous non-use is not, and EL bigger. But accelerator NA-22, DCP used in an amount within a wide range, the appearance of normal. No accelerant NA-22 时, DCP only between 1.8 to 2.1 parts, or easy blistering, poor appearance. Asker C hardness, deformation and apparent density is not very different.

2.5 TAC and the impact of the DCP

TAC both as an organic active agents, but also as a co-crosslinking agent peroxide curing [1]. This, the author studied the synergistic effect of TAC and DCP, without adding magnesium oxide and accelerators NA-22, the agent 64 EVA foam manufacturer to the amount of 15 parts by mass changes in performance concrete results in Table 5.

From Table 5, TAC and DCP content increased, EL showed a downward trend, RL presents no regularity, hardness is not very different appearance to TAC as 1.5 parts, DCP 2.5 to 2.75 parts best.
