●配合比率是以最佳配比值為基礎,此配比值會隨添加的顏料助劑種類和添加量不同而變化。
Matching ratio is based on the optimal matching value which will vary with the category and additive amount of paint additives added.
●自由泡沫密度會依季節(溫度,濕度)的不同而變化。
Free foam density will vary with the seasons (temperature, humidity).
●脫模時間會隨成型品厚度的增加而延長。
Stripping time will be extended with the increase of the thickness of moldings.
●耐折條件:屈撓角度為 90度,頻率為80次/min*4萬次。
Folding endurance conditions: bending angle is 90 degrees and the frequency is 80 times / min * 40 thousand times
