    4. 成型條件及物性值(Molding conditions & physical properties):
     
     
    ●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
     
    ● 以上數據僅作參考,具體數據以實際操作為準。如需其他物性指標,請與我公司聯系。
     
    Data listed above is just for reference. The specific data is subjected to the practical operation. If other physical properties are required, please contact us.
