From Table 2 , EVA FOAM MANUFACTURER / CPE is 40 /60 , the amount of 180 parts of filler , the refining process is the best . This is because the CPE adding , changing the EVA FOAM MANUFACTURER operating temperature ; CPE , the more energy at lower temperatures package roll roll ; less if the filler , it will cause sticky roller , indicating CPE compatibilizer , and can be heavily padded .

2.3 of magnesia

CPE should not use sulfur vulcanization requires magnesium accelerator NA-22 , etc. crosslinking . First investigated EVA FOAM MANUFACTURER / CPE = 60/40 when ( after the same ) , magnesium oxide dosage on the experimental results , the results are shown in Table 3 .

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 .
