3 Properties of PU resin:
|Name of articles||Apperance||Viscosity(pa.s/40ºC)||Density(g.cm³/40ºC)|
|A-808||Liquid or waxy||1100-1450||1.16-1.19|
|B-8650||Transparency without any impurity||300-600||1.19-1.22|
* Addtion of water depends on adjusting of product's density and types,generally,outsole(20-
* Generally,for Catalysts,its addition,outsole(300±20g/18kg),but urually depends on mould cavity and demoulding time.
5 Moulding conditions and material parameters
|Reactivity||Technical parameters||Test items||Material parameters|
|Proportion for reference(P+C/1)||Outsole 100:80-83|
|Finished density(g/cm³)||Outsole 0.8-0.9|

|Hardness(Shore C)||Outsole 70-80|
|Cream time(S)||Outsole 5-7|
|Tensile strength(Mpa)||10-15 Mpa|
|Foamed time||16-23||Tear strength(KN/m)||35-45(KN/m)|
|Free foaming density(g/cm³)||Outsole 0.38-0.45|
|Fold-resistant(D1052 ASTM standard)||Slotless beyond 5million times|
|Demould time(min)||3-5||Abrasion resistance(%)||≥50|
|Metal grinding temperature(ºC)||40-50||Elongation(%)||500-650|
* Free foaming density will be changed according to the changing of seasons,temperature and humidity.
* Demoulding time will be longer than ever with the increased thickness of finished products.
* The above mentioned only for reference,but for other more elements,please test their applicability before using,such as formula,manufacturing technique,applications and so on,otherwise,we have no responsibility for these.
