( 3 ) physical and mechanical properties at HG/T3086-1999 testing.

Asker C hardness at HG/T2489-1993, dense layer without removing the surface of the sample tested ; compressive deformation at HG/T2876-1997 test ; apparent density by HG/T2872-1997 tested.

( 4 ) the appearance of quality determination: visual to the naked eye , the surface no bubbles, no porosity profile as normal .

2 Results and discussion

2.1 EVA FOAM MANUFACTURER / CPE and influence than with

EVA FOAM MANUFACTURER changed from 60 to 30 parts by mass ( the same below ), CPE changed from 40 to 70 , appropriate adjustments to curing system , with different ratios shown in Table 1 .

From Table 1, and with the increased use of CPE , EL decreases , RL synchronization becomes smaller , hardness of the rise. When EVA FOAM MANUFACTURER / CPE = 60/40, the appearance of normal , need to vulcanization and EVA foam manufacturer preferred system , eliminating bubbles and pores.

2.2 CPE Capacity of impact

CPE has high filling, good compatibilization . The effects of EVA FOAM MANUFACTURER / CPE were 40 /60 and 60/ 40, the rate of gel different results ( see Table 2 ) .
