●配合比率是以最佳配比值为基础，此配比值会随添加的颜料助剂种类和添加量不同而变化。
Matching ratio is based on the optimal matching value which will vary with the category and additive amount of paint additives added.
●自由泡沫密度会依季节（温度，湿度）的不同而变化。
Free foam density will vary with the seasons (temperature, humidity).
●脱模时间会随成型品厚度的增加而延长。
Stripping time will be extended with the increase of the thickness of moldings.
●耐折条件：屈挠角度为 90度，频率为80次/min*4万次。
Folding endurance conditions: bending angle is 90 degrees and the frequency is 80 times / min * 40 thousand times
