Molding conditions & physical properties:
|Reactivity||Technical index||Test item||Reference physical properties|
|Reference ratio P+C/I||100/83-85||Molded density of sole（g/cm3）||0.45~0.55|
|Material temperature（℃）||A material: 45-50; B material:38-42||Hardness (type A)||40~50|
|Cream time（s）||7~9||Tensile strength（MPa）||6.0~8.0|
|Metal mold temperature（℃）||45~55||NBS abrasion resistance（％）||≥10%|
|Demould time（min）||3.0~5.0||Free foam density（g/cm3）||0.25~0.30|

Matching ratio is based on the optimal matching value which will vary with the category and additive amount of paint additives added.
Free foam density will vary with the seasons (temperature, humidity).
Stripping time will be extended with the increase of the thickness of moldings.
Folding endurance conditions: bending angle is 90 degrees and the frequency is 80 times / min * 40 thousand times
